<2> Example of output to the channel 1 Internal data is output to channel 1 by setting it in an 8-bit D/A convertor. The output range of the D/A convertor varies from one printed- circuit board to another. The output ranges from -5 V to +5 V (printed-circuit board A20B-2001-0830) or from 0 V to +11 V (printed-circuit board A20B-1005-0740) according to the internal data that is set. See the table below.

5.1.1 Installing a Special Lithium Battery in the SVM (Method 1)
A special lithium battery (A06B-6073-K001) can be installed in the SVM (see the figure below).
[Installation procedure] (1) Remove the battery cover from the SVM. (2) Install the battery in the SVM as shown in the figure below. (3) Install the battery cover. (4) Attach the battery connector to CX5X or CX5Y of the SVM.

WARNING 1 Install the battery with correct polarity. If the battery
is installed with incorrect polarity, it may overheat, blow out, or catch fire.
2 When installing the battery with its connector attached to connector CX5X or CX5Y, attach the factory-installed protection socket to the unused connector. When the +6-V and 0-V pins of CX5X or CX5Y are short-circuited, the battery may overheat, blow out, or catch fire.
CAUTION 1 You may attach the battery connector to either CX5X
or CX5Y. 2 When the battery is installed in the SVM from the
side from which the cable is drawn, the cable may be stretched tight, which can lead to a poor contact condition. Therefore, install the battery so that the cable is not extended tightly.

5.1.4 Replacing the Battery
To prevent absolute-position information of the absolute pulse coder from being lost, replace the battery while the power for control is on. Follow the procedure explained below.
1. Make sure that the power to the SVM is on (the 7-segment LED on the front of the SVM is on).
2. Make sure that the emergency stop button of the system has been pressed.
3. Make sure that the motor is not activated.
4. Make sure that the DC link charge LED of the SVM is off.
5. Remove the old battery, and install a new battery.
6. This completes the replacement. You can turn off the power to the system.
WARNING 1 When replacing the battery, be careful not to touch
bare metal parts in the panel. In particular, be careful not to touch any high-voltage circuits due to the electric shock hazard.
2 Before replacing the battery, check that the DC link charge confirmation LED on the front of the servo amplifier is off. Neglecting this check creates an electric shock hazard.
3 Install the battery with correct polarity. If the battery is installed with incorrect polarity, it may overheat, blow out, or catch fire.
4 When installing the battery with its connector attached to connector CX5X or CX5Y, attach the factory-installed protection socket to the unused connector. When the +6-V and 0-V pins of CX5X or CX5Y are short-circuited, the battery may overheat, blow out, or catch fire.

(1) Make sure that the motor is not vibrating. ⇒ If a motor vibrates, the current flowing in it becomes more
than necessary, resulting in an alarm.
(2) Make sure that the power line to the motor is connected correctly. ⇒ If the connection is incorrect, an abnormal current flows in
the motor, resulting in an alarm.
(3) Make sure that the following parameters are set correctly. ⇒ An overload alarm is issued based on the result of calculation
of these parameters. Be sure to set them to the standard values. For details of the standard values, refer to the parameter manual (B-65150E).

Action 2: This alarm is issued when the position feedback pulse variation is small relative to the velocity feedback pulse variation. This means that this alarm is not issued when a semi-full is used. Check if the separate detector outputs position feedback pulses correctly. If position feedback pulses are output correctly, it is considered that the motor alone is rotating in the reverse direction at the start of machine operation because of a large backlash between the motor position and scale position.

Check if a battery is connected. When the power is turned on for the first time after a battery is connected, the zero battery voltage alarm is issued. In such a case, turn off the power, then turn on the power again. If the alarm is still issued, check the battery voltage. If the battery voltage decrease alarm is issued, check the voltage, and replace the battery as required.
Action 2: Alarms that may be issued for noise If an alarm is issued intermittently or after emergency stop cancellation, noise is probably the cause. So, provide noise protection. If the same alarm is still issued after noise protection is provided, replace the detector.
