If a system alarm occurs in a CNC using the connector panel I/O module, or if I/O Link communication between the CNC and connector panel I/O module fails, all the DO signals of the I/O module are turned off. Therefore, due care must be taken when setting up the machine sequence. Also, the same phenomenon occurs if the power to the CNC or the I/O module is turned off.
For the connector panel I/O module, I/O addresses are mapped as follows.

The basic connector panel I/O module is allocated a group of DI addresses (16 bytes) and a group of DO addresses (8 bytes). Up to three hardware extension modules can be added or removed as required. The reason for this address allocation is explained below. The MPG interface (MPG counter) occupies a DI space from Xm+12 through Xm+14. These addresses are fixed regardless of whether extension module 2 or 3 is used, and Xm+12 through Xm+14 must be allocated as a DI work area to enable the use of the MPG. Therefore, when using an MPG for the i series CNC, allocate DI addresses in units of 16 bytes. Do not use the DI space from Xm+12 through Xm+14 for Ladder; the CNC processes the MPG counter value directly. DI address Xm+15 is used for detecting overcurrent and overheating alarms that occur in the IC used in the DO driver. [For details, see the section describing the detection of DO (output signal) alarms.] This address is fixed regardless of whether extension module 2 or 3 is used, and it must be allocated as a work area before it can be used. When using this area, therefore, allocate DI addresses in units of 16 bytes. Basically, I/O addresses can be allocated to the connector panel I/O modules freely. When allocating DI addresses, however, consider also the addresses that are directly supervised by the CNC, and keep the following in mind.

The DO driver of the Basic and Extension module A/B is capable of detecting an overcurrent and measuring its own temperature. If an accident, such as the connecting of the cable to ground, causes an abnormal increase in the load current or in the driver temperature, a protection circuit, which is provided for each DO driver (1 byte), is activated and keeps the DO signal for the relevant 1 byte in the OFF state until the cause of the problem is eliminated. Even if this occurs, the CNC and I/O module continue operating. The DI address (Xm+15) identifies the DO driver which has detected the alarm. The following table shows the correspondence between the DI address (Xm+15) bits and the DO addresses. Bit value “1” indicates that the corresponding DO driver has detected an alarm. The contents of the Xm+15 area can be checked by using the DGN screen of the CNC or by performing alarm processing for the area in advance by using Ladder. This helps alarm detection and recovery.

NOTE This function is not supported by the 2A output module or analog input module.
Allocation of the 2A output module and analog input module The 2A output module and analog input module can be allocated to any of the spaces for expansion modules 1, 2, and 3. In addition, up to three 2A output modules or analog input modules can be allocated to all the spaces for expansion modules 1, 2, and 3. When an MPG interface is required, the module occupies the space for expansion module 1; no 2A output module or analog input module can be allocated in the space for expansion module 1. The 2A output module does not involve DI points, so that the DI area of the space in which a 2A output module is allocated is unusable. When a 2A output module is allocated to the space for expansion module 2, for example, the areas from Xm+6 to Xm+8 cannot be used. (The spaces for the other modules are not shifted. In this case, the DI space of expansion module 3 remains at Xm+9 through Xm+11.)

NOTE Xm+1.0 through Xm+1.7 are DI pins for which a common voltage can be selected. That is, by connecting the COM1 CE54(A02) pin to the +24 V power supply, a DI signal can be input with its logical state reversed. If, however, a cable is connected to ground, it has the same effect as inputting an ON state DI signal. To prevent this from occurring, the connection of the COM1 CE54(A02) pin to the 0 V power supply is recommended whereever possible. For safety reasons, the emergency stop signal needs to be allocated to an appropriate bit of the addresses for which the common voltage is fixed, ranging from Xm+0.0 to Xm+0.7. See “Address allocation” in Section 9.5.10 for details of how to allocate the emergency stop signal. For unused DI pins allocated to the addresses for which the common voltage is fixed (from Xm+1.0 to Xm+1.7), the logic is fixed to “0”. For unused pins allocated to Xm+1.0 to Xm+1.7 for which the common voltage can be selected, the logic is fixed to “0” when the COM1 CE54(A02) pin is connected to the 0 V power supply. When the COM1 CE54(A02) pin is connected to the +24 V power supply, the logic is fixed to “1”. The logic of the unused pins allocated to Xm+1.0 to Xm+1.7 is variable when the contact of the COM1 CE54(A02) pin is open.

If a system alarm occurs in the CNC using the operator’s panel I/O module, or if I/O Link communication between the CNC and operator’s panel I/O module fails, all the DO signals of the I/O module are turned off. Therefore, sufficient care is necessary when setting up the machine sequence. Also, the same phenomenon occurs if the power to the CNC or the I/O module is turned off.
For the operator’s panel I/O module, I/O addresses are mapped as follows.

The operator’s panel I/O module is allocated a group of DI addresses (16 bytes) and a group of DO addresses (8 bytes). This address allocation is explained below.
The MPG interface (MPG counter) occupies DI space from Xm+12 through Xm+14. These addresses are fixed, and Xm+12 through Xm+14 must be allocated as a DI work area to enable the use of the MPG. Therefore, when using an MPG for the I series CNC, allocate DI addresses in units of 16 bytes. Do not use the DI space from Xm+12 through Xm+14 for Ladder; the CNC processes the MPG counter value directly.
DI address Xm+15 is used for detecting overcurrent and overheating alarms that may occur in the IC used in the DO driver. [For details, see the section describing the detection of DO (output signal) alarms.] This address is fixed, and must be allocated as a work area before it can be used. Therefore, when using this area, allocate DI addresses in units of 16 bytes.
Basically, I/O addresses can be allocated to the operator’s panel I/O module freely. When allocating DI addresses, however, consider also the fixed addresses that are directly supervised by the CNC, and keep the following in mind.

All the DO signals can be turned off simultaneously by turning off (opening) the DO (output signal) power supply pin “DOCOM”. Doing so causes the DO signal status to change as shown below.
 CONNECTION TO FANUC I/O Link
277
NOTE When the DO signal is in the ON state in the sequence, the ON or OFF state of the DOCOM pin determines the state of the signal, as indicated by the dotted lines in the above figure. Do not turn off the +24 V supply, provided by the CPD1 to the I/O module, during the operation. Turning off the +24 V supply would cause a CNC communication alarm. When turning on the power, the +24 V supply to the I/O module must be turned on before or at the same time as the power supply to the CNC. When turning off the power, the +24 V supply to the I/O module must be turned off after or at the same time as the power supply to the CNC.
The DO load current can be doubled by connecting two DO points in parallel and turning them on and off simultaneously in sequence, as shown in the figure below. The maximum load current per DI point is 200 mA. Connecting two DO points in parallel and turning them on at the same time produces a current of 400 mA. Note that, however, when two DO points are connected in parallel, the leakage current also doubles while they are off (max. 40 mA).

The DO driver of the I/O module is capable of detecting an overcurrent and measuring its own temperature. If an accident, such as connecting the cable to ground, causes an abnormal increase in the load current or in the driver temperature, a protection circuit, which is provided for each DO driver (1 byte), is activated which keeps the DO signal for the relevant 1 byte in the OFF state until the cause of the problem is eliminated. Even if this occurs, the CNC and the I/O module continue operating. The DI address (Xm+15) identifies which DO driver has detected an alarm. The following table shows the correspondence between the DI address (Xm+15) bits and the DO addresses. Bit value “1” indicates that the corresponding DO driver has detected an alarm. The contents of the Xm+15 area can be checked by using the DGN screen of the CNC or by performing the alarm processing for the area in advance by using Ladder. This helps alarm detection and recovery.

NOTE Xm+0.0 through Xm+0.7 and Xm+5.0 through Xm+5.7 are DI pins for which a common voltage can be selected. That is, by connecting the DICOM0 CE56(A14) or DICOM5 CE57(B14) pin to the +24 V power supply, a DI signal can be input with its logical state reversed. If, however, a cable is connected to ground, it has the same effect as inputting an ON state DI signal. To prevent this from occurring, the connection of the DICOM0 CE56(A14) and DICOM5 CE57(B14) pins to the 0 V power supply is recommended whereever possible. For safety reasons, the emergency stop signal needs to be allocated to an appropriate bit of the addresses for which the common voltage is fixed. See “Address allocation” in Section 9.6.9 for details of how to allocate the emergency stop signal. For unused DI pins allocated to the addresses for which the common voltage is fixed, the logic is fixed to “0”. For unused pins allocated to the addresses for which the common voltage can be selected, the logic is fixed to “0” when the DICOM0 CE56(A14) or DICOM5 CE57(B14) pin is connected to the 0 V power supply. When the DICOM0 CE56(A14) or DICOM5 CE57(B14) pin is connected to the +24 V power supply, the logic is fixed to “1”. The logic of the unused pins is variable when the contacts of the DICOM0 CE56(A14) and DICOM5 CE57(B14) pins are open.

The DO driver of the I/O module is capable of detecting an overcurrent and measuring its own temperature. If an accident, such as the connecting of the cable to ground, causes an abnormal increase in the load current or in the driver temperature, a protection circuit, which is provided for each DO driver (1 byte), is activated and keeps the DO signal for the relevant 1 byte in the OFF state until the cause of the problem is eliminated. Even if this occurs, the CNC and I/O module continue operating. The DI address (Xm+15) identifies the DO driver which has detected the alarm. The following table shows the correspondence between the DI address (Xm+15) bits and the DO addresses. Bit value “1” indicates that the corresponding DO driver has detected an alarm. The contents of the Xm+15 area can be checked by using the DGN screen of the CNC or by performing alarm processing for the area in advance by using Ladder. This helps alarm detection and recovery.

� Preventing malfunctions that may be caused by detouring current When there are three or more matrix DI points, detouring current can cause a nonexistent DI input to be falsely detected as existing. As shown below, if KY01, KY03, and KY21 are closed simultaneously, current detours through the path indicated with arrows, thus causing a false input of *KY23 to be detected because of a current path formed by a combination of common signal *KYC2 and data signal *KYD3.

Two modes are available to prevent this malfunction. One should be selected according to the user applications. [Method 1] � Ignoring all occurrences of three or more simultaneous inputs
Action : Make the *MNDI signal open (see item “� Key switch addresses”)
NOTE If there are two inputs and a third is added, all three are ignored. When one of the three inputs is removed, two are accepted.
[Method 2] � Attaching detour prevention diodes to enable three simultaneous
inputs Action : Connect the *MNDI signal (see item “� Key switch
addresses”) to 0V.
A diode must be connected in series with a switch, as shown below.

� This PCB can raise a confirmation sound when a key is pressed. The condition to raise an audible alarm is set in 8–bit units, or in *KYCn units. If *BZMD and common *KYCn are disconnected, a KYnx input causes a sound to generate. If they are connected, a KYnx input does not generate the sound. To generate a confirmation sound for key input, the DO (PMC address DO + 00.7) “MD07” must have been turned to “1” (see Subsec. 10.7.5).
1 A diode is necessary to connect *BZMD and *KYCn, as shown below.
2 This setting cannot be changed when power is supplied. 3 The sound is generated when the circuit closes between
common signal *KYCn and data signal *KYDx. It does not sound when the circuit is disconnected. If key switches are used, the sound is heard at the moment a key is pressed. It does not sound when a key is released or when a key is held pressed.
*KYCn
*BZMD
(Example) If *BZMD is connected to *KYC0 and *KYC2, but disconnected from *KYC1 and *KYC3, as shown below, closing a switch at key addresses KY10 to KY17 and KY30 to KY37 causes a confirmation sound for key input to be heard, but closing a switch at key addresses KY00 to KY07 and KY20 to KY27 does not.

WARNING All signals input to this operator’s panel connection unit are of source type. When a source interface is used, a ground fault in an input signal has the same effect as closing the contacts. From the viewpoint of safety, therefore, FANUC does not recommend the use of such an interface for input signals. In particular, input signals X008.0 to X008.7 must be connected in a sink layout, because these signals include the emergency stop signal. Do not use this operator’s panel connection unit for safety–critical input signals (such as an emergency stop signal).

Output signals DO00 to DO77 of the operator’s panel connection unit drive indicators and LEDs on the machine operator’s panel and use NPN transistor for drivers. Prepare 24VDC for power supply of indicators and LEDs and connect 0V to COM3 and COM4. For LEDs, however, 5VDC 300mA output from the terminal +5N of the connector CM3 can be used. There is no +5N in the connector CM4; use +5N in connector CM3 as shown below:

The operator’s panel connection unit (A16B–2202–0730, 0731), which connects to the control unit via the FANUC I/O Link, acts as an interface with the machine operator’s panel. Connectors CM51, CM52, CMB3, and CMB4, used to interface with the operator’s panel, feature an electrical interface and pin assignment which are fully compatible with those of the source type output operator’s panel connection unit for the Series 15. The following two units are available with different numbers of I/O points:

In the above figure, logical 0 corresponds to open contacts, while logical 1 corresponds to closed contacts.
WARNING When a source interface is used, a ground fault in an input signal has the same effect as closing the contacts. From the viewpoint of safety, therefore, FANUC does not recommend the use of such an interface for input signals.
The output signals shall satisfy the following:
Maximum load current when driver is on: 200 mA (including momentary values)
Saturation voltage when driver is on: 1.0 V max.
Withstand voltage: 24 V +20% (including momentary values) Leakage current when driver is off:
100 mA
Prepare the following external power supply for the output signals:
Supply voltage: +24 V " 10% Supply current (per board):
At least total maximum load current (including momentary values) + 100 mA
Power–on timing: At the same time as or before turning on the power to the control unit
Power–off timing: At the same time as or after turning on the power to the control unit
10.9.2 Output Signal Specifications for Source Output Type Connection Unit
10. CONNECTION TO FANUC I/O Link B–63003EN/03
328
CAUTION A power supply which satisfies the above specifications shall be connected to the DOCOM and 0V power supply terminals for the output signals. The maximum current that can be carried by the DOCOM pin is 2.0 A. The total load current must not exceed this value, therefore.
The output signal driver used with the operator’s panel connection unit can output up to eight signals.
The driver element monitors the current of each output signal. If an overcurrent is detected, the output of that signal is turned off. Once a signal has been turned off, the overcurrent will no longer exist, such that the driver turns the signal on again. Therefore, in the case of a ground fault or overload, the output of a signal will be repeatedly turned on and off. This also occurs when a load which causes a high surge current is connected.
The driver element contains an overheat detector, which turns off all eight output signals if the temperature in the device exceeds the set value as a result of an overcurrent caused by a ground fault or some other failure. This off state is held. To restore signal output, logically turn the output off then back on again, for each signal, after the temperature falls below the set value. Signal output can also be restored by turning the system power off then back on again.
On the PCB, a red LED beside the driver element lights once the overheat detection circuit operates.
NOTE The overheat detection circuit also causes a system alarm to be issued to the CNC. (When setting pins CP1 on the PCB are closed (jumpered), this alarm is not issued to the CNC.)

NOTE The above red LED and alarm transfer to the CNC are supported by PCBs of version 03B and later.
If the output of a signal cannot be turned on even though the CNC diagnostic indicates that the signal is on, that signal or another signal being handled by the same element may be overloaded, thus causing the eight output signals to be turned off. In such a case, turn the system power off and eliminate the cause of the overload.

NOTE This system enables I/O data transfer between two independent FANUC I/O Link master devices. When the system is adjusted and maintained, the FANUC I/O Link can be operated with the system power for one of the FANUC I/O Link lines switched off, that is, the link operation is stopped. In this case, DI data sent from a system at rest consists entirely of zeros. If one of the links is stopped, either abnormally or normally, it takes up to several hundred milliseconds for this function to take effect. During this period, that data which exists immediately before the link stops is sent out. Take this into account when designing your system.

Item Specification
I/O Link function Provided with two slave mode I/O Link interface channels, between which DI/DO data can be transferred.
[Interface types] One of the following combinations is selected:
Electrical – optical Electrical – electrical Optical – optical
Number of DI/DO data items
DI: Up to 256, DO: Up to 256 (The number of data items actually used varies depending on the amount of data assigned in the host.)
Power supply Each I/O Link interface must be independently supplied with +24 VDC.
Voltage: +24 VDC +10%, –15% Current: 0.2 A (excluding surge)
If a master unit does not have sufficient capacity to supply power to each unit (0.2 A per slot), use an external power supply unit. The power supply must be switched on, either simultaneously with or before, the I/O Link master. The two systems can be switched on and off independently of each other. Data from a system to which no power is supplied appears as zeros when viewed from the other system. The data becomes 0 within 200 ms of the power being switched off.

The FANUC servo unit β series with I/O Link (called the β amplifier with I/O Link) is a power motion control servo unit that can be easily connected to a CNC control unit via the FANUC I/O Link. The β amplifier with I/O Link can be connected to the i Series using the FANUC I/O Link.
NOTE Using the β amplifier requires that the power mate CNC manager software function be installed in the i Series. This function is included as one of the i Series option functions. Note that this function is not supported by the i Series with personal computer functions also requires an optional CNC screen display function.

The maximum number of β amplifiers with I/O Link that can be connected to a control unit depends on the maximum number of FANUC I/O Link points provided by that control unit, as well as their assignments. For the i Series, the maximum number of FANUC I/O Link DI and DO points are 1024 and 1024, respectively. One β amplifier with I/O Link occupies 128 DI/DO points in the FANUC I/O Link. If no units other than the β amplifiers with I/O Link are connected to the control unit, up to eight β amplifiers can be connected.
If the β amplifier with I/O Link is used as an I/O Link slave, I/O addresses are assigned in the PMC in the CNC. Because data output from the slave is made in 16–byte units, the number of input/output points must be set to 128.
The module names are PM16I (input) and PM16O (output). The BASE is always 0, and the SLOT is 1.

NOTE 1 Xm+1.0 to Xm+1.7 and Xm+3.0 to Xm+3.7 are DI points that
allows common selection. This means that by connecting the DICOM1 pin (CM58–A02) and DICOM3 pin (CM58–B02) to +24 V, the DI signal whose logic is inverted can be applied. In this case, however, if the cable is struck by lightning, it has the effect of turning on the DI signal. For safety reasons, therefore, the connection of the DICOM1 and DICOM3 pins to 0 V is recommended whenever possible.
2 From the viewpoint of safety, an emergency stop signal needs to assigned to the corresponding bit of addresses Xm+2.0 to Xm+2.7 tied to the common signal. Determine the location of an emergency stop signal as described in Section 10.12.12.
3 The unused DI points of addresses Xm+2.0 to Xm+2.7 tied to the common signal are used as inputs tied to 0. The unused DI points of addresses Xm+1.0 to Xm+1.7 and Xm+3.0 to Xm+3.7 that allow common selection are input signals tied to 0 when the DICOM1 pin (CM58–A02) and DICOM3 pin (CM58–B02) are connected to 0 V; the unused DI points are input signals tied to 1 when the DICOM1 pin (CM58–A02) and DICOM3 pin (CM58–B02) are connected to +24 V. When the DICOM1 pin (CM58–A02) and DICOM3 pin (CM58–B02) are open, the logic of the unused DI points at addresses Xm+1.0 to Xm+1.7 and Xm+3.0 to Xm+3.7 is undefined.

With the distribution I/O machine operator’s panel, basically allocate a group of 16 bytes as a DI area, and allocate a group of 8 bytes as a DO area. The reason for this is described below. The MPG interface (MPG counter) uses Xm+12 through Xm+14 of the DI space. These addresses are fixed. Xm+12 through Xm+14 must be allocated before the MPG interfaces can be used. So, when using MPG interfaces with the i series, allocate a group of 16 bytes as a DI area. The value of an MPG counter is directly processed by the CNC, so the ladder must not use this area. When MPG interfaces are not used, the DI area may be allocated to other I/O groups.

The keyboard of the machine operator’s panel employs a matrix configuration. If three or more keys are simultaneously entered in the matrix DI configuration, a DI signal is erroneously entered due to an abnormal current flow. A countermeasure for this malfunction can be implemented using a ladder program.
(Protection against malfunction)
If three or more keys are entered in the matrix DI configuration, all key inputs after the first two are invalidated. If there are no additional key inputs after three or more invalidated key inputs, and if the total number of inputs is two or less, all key inputs that have been performed up to that time are valid.

(Ladder operation) The following provides examples of ladder operation based on the DI matrix of 8 (bits) 8 (common), indicated on the next page.
(1)The number of data lines where keys are entered is checked. The OR (R1) of the data of all the addresses is found. Among the eight bits of the R1 data, the number of bits set to 1 represents the number of data lines where keys are entered.
1 The R1 data is compared with 00h. If a match is found, the number of R1 data bits set to 1 is 0.
Example) State (a): R1 = (00000000) ‡ The number of data lines where keys are entered is 0.
2 The R1 data is compared with the data tables below. If the R1 data matches the data in data table 1, the number of R1 data bits set to 1 is 1. Similarly, if the R1 data matches the data in data table 2, the number of R1 data bits set to 1 is 2.
Example) State (b) or (c): R1 = (00000100) ‡ The number of data lines where keys are entered is 1.
Example) State (d) or (e): R1 = (00010100) ‡ The number of lines where keys are entered is 2.
3 If the R1 data is not 00h, and does not match the data of either data table, the number of R1 data bits set to 1 is 3 or more.
Example) State (f): R1 = (00110100) ‡ The number of lines where keys are entered is 3.
00000001 00000010
00000100 00001000
00010000 00100000

10010000 00100001 01000010 10000100
Data table 1 Data table 2
(2)Decision 1
1 When there is no line where keys are entered ‡ No key switch is pressed.
Example) State (a)
2 When there are two or less lines where keys are entered ‡ Go to (3)
3 When there are three or more lines where keys are entered ‡ Three or more keys are entered. This case is invalid.
Example) State (f)
B–63003EN/03 10. CONNECTION TO FANUC I/O Link
367
(3)When there are two or less data lines where keys are entered, whether multiple keys are entered on a data line is checked. The data of all addresses are subtracted from the OR (R1) to obtain result R2. When R2 = 00h, there is no data line where multiple keys are entered.
Example) When there is one data line where a key is entered State (b): R2 = FCh State (c): R2 = F8h
When there are two data lines where keys are entered State (d): R2 = 00h State (e): R2 = FCh
(4)Decision 2
1 When R2 = 00h
‡ There are two or less data lines where keys are entered, and no multiple keys are entered on a data line. In this case, the total number of keys entered is 1 or 2, thus representing valid key input. Example) State (d)
2 When R2 0 00h
‡ There are two or less data lines where keys are entered, and multiple keys are entered on a data line. Go to (5).
(5)Decision 3
1 When there is one data line where keys are entered ‡ Go to (6).
2 When there are two data lines where keys are entered
‡ Three or more keys are entered, thus representing invalid key input. Example) State (e)
(6)The result of subtraction (R2) is added to the OR (R1). When the result of addition is 00h, the total number of keys entered is 2.
Example) State (b): R1 + R2 = 04h + FCh = 00h State (c): R1 + R2 = 04h + F8h = FCh
(7)Decision 4
1 When R1 + R2 = 00h
‡ There is one data line where keys are entered, and two keys are entered on the data line. This means that the total number of keys entered is 2, representing valid key input. Example) State (b)
2 R1 + R2 0 00h
‡ Three or more keys are entered on a data line, thus representing invalid key input. Example) State (c)
(8)Only when valid key input is confirmed by decisions 1 through 4, all DI data (Xm+4 to Xm+11) is used by the ladder program.

B–63003EN/03 11. EMERGENCY STOP SIGNAL
377
11 EMERGENCY STOP SIGNAL Using the emergency stop signal effectively enables the design of safe machine tools. The emergency stop signal is provided to bring a machine tool to an emergency stop. It is input to the CNC controller, servo amplifier, and spindle amplifier. An emergency stop signal is usually generated by closing the B contact of a pushbutton switch. When the emergency stop signal (*ESP) contact is closed, the CNC controller enters the emergency stop released state, such that the servo and spindle motors can be controlled and operated. When the emergency stop signal (*ESP) contact opens, the CNC controller is reset and enters the emergency stop state, and the servo and spindle motors are decelerated to a stop. Shutting off the servo amplifier power causes a dynamic brake to be applied to the servo motor. Even when a dynamic brake is applied, however, a servo motor attached to a vertical axis can move under the force of gravity. To overcome this problem, use a servo motor with a brake. While the spindle motor is running, shutting off the motor–driving power to the spindle amplifier allows the spindle motor to continue running under its own inertia, which is quite dangerous. When the emergency stop signal (*ESP) contact opens, it is necessary to confirm that the spindle motor has been decelerated to a stop, before the spindle motor power is shut off. The FANUC servo amplifier α series products are designed to satisfy the above requirements. The emergency stop signal should be input to the power supply module (called the PSM). The PSM outputs a motor power MCC control signal, which can be used to switch the power applied to the power supply module on and off. The CNC controller is designed to detect overtravel by using a software limit function. Normally, no hardware limit switch is required to detect overtravel. If the machine goes beyond a software limit because of a servo feedback failure, however, it is necessary to provide a stroke end limit switch, connected so that the emergency stop signal can be used to stop the machine. Fig. 11 shows an example showing how to use the emergency stop signal with this CNC controller and α series control amplifier.
