It is easy to mount and dismount the CNC power supply unit, because it is designed to be mounted on, and connected directly to, the master printed–circuit board. All its AC inputs and DC outputs are linked via connectors.
Because this power supply unit has a built–in input unit function, it is not necessary to prepare a separate relay or input unit for switching the AC input on and off. The AC input can be connected directly to the power supply unit. The unit has an AC service outlet, which is switched on and off simultaneously with the power supply unit. This AC service outlet can be used to supply power to a unit such as a fan motor.

(c) Short circuit between the collector and emitter of switching transistors Q14 and Q15
(d) Short circuit in diodes D33 and D34
(e) Short circuit between the collector and emitter of transistor Q1 in the auxiliary power supply circuit
If you suspect that any of short circuits (b) to (e) has occurred in the respective parts, replace the power supply unit with a spare. When replacing a fuse, use a replacement having the same rating. The specification number for fuses F11 and 12 is A60L–0001–0245#GP75.
2. Fuse F13 (a) A short circuit may have occurred in the CRT/MDI unit or a
+24 V power supply cord leading to it. Remove the cord from CP15, and check the unit and cord carefully.
(b) A short circuit may have occurred in the +24 V circuit on the master printed–circuit board. Remove the cable from CP14 and CP15.

4. Fuse F1 Fuse F1 and surge absorber VS1 are wired so that, if a high current flows through VS1, it may cause F1 to blow. This is intended to protect the circuits in the power supply unit from an abnormal voltage that may occur due to a failure in the auxiliary power supply circuit of the power supply unit and an abnormal voltage that may originate in the power supply ON/OFF switch contact signal line or external alarm signal line. If F1 blows, probable causes are:
(1) Failure in the auxiliary power supply circuit (M1, Q1, T1, D1, Q2, or ZD1)
(2) False contact between the power supply ON/OFF switch contact signal line or external alarm signal line and the AC power line
If cause (1) is more likely, replace the power supply unit. If cause (2) is more likely, replace the power supply unit, because the power supply unit may have failed. After the power supply ON/OFF switch contact signal line and external alarm signal line have been checked, and all abnormal conditions (if any) have been cleared, if replacing F1 restores normal operation, there is no need to replace the power supply unit. The specification number of fuse F1 is A60L–0001–0172#DM03. When replacing the fuse, use a replacement having the same rating.

It is necessary to regulary clean the heat transformer, because the heat transformation ability will be reduced by the accumulation of dust. The frequency of the cleaning needed differs according to the installation environment and therefore should be determined by your own judgment according to the degree of dirt.
Air filter cleaning and replacement method
1 When cleaning and replacing the filter, be sure to cut off the fan’s electric power source.
2 Detach the filter cover and take out the filter inside.
Detach the cover by pressing, the flanges which are in the grooves of both sides towards the inside by minus screwdriver, etc.
3 Protect the filter from silting due to dust by blowing air on both sides.
4 When dirt is conspicuous, press wash with a neutral detergent, rinse with fresh water, and the washing, allow to dry naturally. When replacing with the same product.
5 Insert the filter in the cover, align the flange in the groove, and install by pressing. Confirm that the cover will not come loose even if it is pulled.

When there are no dog nor limit switch for reference position return, this function enables the tool to return the reference position that is set by MTB. When the absolute position detector is used, the reference position once set remains also during power off. When the absolute detector is replaced or absolute position is lost, perform this setting.

2 Select the reference position return mode or switch.
3 Press a button for an axis–and–direction–select–signal + or –, and the machine moves to the next grid, then stops. (This position is set as the reference position). After the reference position has been set, select the reference position return mode(ZRN signal is 1) and turn on an axis–and–direction– select signal, then the tool returns to the reference position.

Check the LED on the input unit or power supply unit AI.
(1) If no power supply alarm is detected (the red ”ALM” LED does not light):
1. If the PIL LED is off:
(a) Check the input fuse of the input unit or power supply unit AI. Measure the voltage across the R and S terminals on the screw–on terminal strip of the input unit or at the connector CP1 of the power supply unit AI using a volt–ohm–milliammeter, and check whether 200 VAC is available. If the 200 VAC cannot be detected at connector CP1, check the corresponding circuit in the machine.
(b) If both the fuse and power supply voltage are normal, the printed–circuit board of the input unit or the power supply unit AI may be defective.
2. If the PIL LED lights, and the input voltage is normal: Check whether the conditions for switching the power on are satisfied.
When power is turned on with the connector CP11 at the bottom of the power supply unit detached, if a voltage of 200 VAC appears across pins 1 and 2 for about one second, it means that an ON condition is satisfied. (This method is not applicable to the power supply unit AI.)

(2) If a power supply alarm is detected (the red ”ALM” LED lights):
The most likely causes are a failure (short circuit or ground fault) or a defective power supply unit. Use the check procedure described below.
NOTE Do NOT detach the memory backup battery cable.
1. Switch the power off, then check for a short circuit or ground fault between the DC voltage check terminals (+5V, +15V, –15V, +24V, and +24E) and the 0V point. (Overcurrent) If a short circuit or ground fault is detected, locate its cause by unhooking the related connectors, one by one, and measuring the resistance of each cable.
2. If a short circuit is still detected after all related connectors have been unhooked, remove the printed–circuit boards from the control section, one by one, to determine whether any printed–circuit board is short–circuited.
3. If neither a short circuit nor a ground fault is detected, check whether the input unit operates normally. (This method is not applicable to the power supply unit AI.) (a) Remove the connector CP11 from the bottom of the power
supply unit, and measure the voltage across pins 1 and 2. If 200 VAC is output for about one second after the power on button is pressed, at least half the input unit is normal.
(b) With the connector CP11 detached, connect pins 5 and 6 with a jumper wire, then turn on the power. If 200 VAC is output continuously, the input unit is normal.

Absolute position data in the serial pulse coder was lost. (This alarm will be generated when serial pulse coder is exchanged or position feedback signal cable of the serial pulse coder is disconnected).
Machine position must be memorized using the following method:
(1) Execute manual reference position return only for an axis for which this alarm was generated.When manual reference position return cannot be executed because of an another alarm, change parameter 0021 and release the alarm and perform manual operation.
(2) Press RESET key at the end of reference position return to release the

Execute dogless reference position setting to memorize the reference position.
Since the reference position is different from the former one, change the grid shift value (PRM No.508 to 511, 641, 642, 7508, 7509) to correct the position.

2 Turn machine (CNC) power ON. (When replacing the batteries, keep the power to the NC switched on. If the batteries are replaced with the power switched off, all data relating to the absolute position will be lost.)
3 Loosen screws on the battery case to remove the cover. For placement of the battery case, refer to the machine tool builder’s manual.
4 Replace the batteries in the case. Insert 2 batteries each in the opposite direction as illustrated below.

1 Check the contens using the above diagnostic function if the alarm generates repeatedly. If diagnostic data is the same, serial pulse coder may be faulty.⇒ Refer to NOTE
2 When diagnostic result does not the same, or other abnormality is detected, an external noise may be generated.
NOTE Reference position and machine’s standard position are different from the ones before, adjust and set them correctly.
