6.10 Servo Amplifier Battery
Point
CP-842E/842ME machines use absolute encoder motors with servo amplifiers that are
equipped with back-up batteries for saving the encoder data when the machine main
power is off.
When the servo amplifier battery voltage falls below a certain range, a "Servo amp error"
message appears on the machine operation screen during start-u,p and "A.83" is
displayed at the servo amplifier's LED indicator. Replace the battery at this time.
Caution:
1. The absolute data is saved for approximately 1 week after the A.83 error first occurs. Failure
to replace the battery during this period results in the loss of the absolute encoder data. The
battery should therefore be replaced quickly, otherwise calibration data will have to be re-
measured.
2. The absolute encoder data will be lost if the old battery is removed while the servo amplifier'
power LED is off. Ensure that the machine power and amplifier power LED are ON when
removing the old battery.

Procedure
Replace the servo amplifier battery with the machine power on.
1 Verify that the machine's [SYSTEM ON] lamp is on.
2 Press the EMERGENCY STOP button. This disables the 200V power supply.
3 Identify the servo amplifier where "A.83" is displayed at the LED.
4 Locate the battery in the case located at the upper front of the servo amplifier
and replace it with a new battery.
CP-842E/842ME machines use the following 2 battery types in servo amplifiers
• Servo amplifier capacity: 30w to 5kw
Model: JZSP-BA01
• Servo amplifier capacity: 6kw, 7.5kw
Model: JZSP-BA01-01
Caution:The absolute encoder data will be lost If the old battery is removed while the servo amplifier
power LED is off. Ensure that the power LED is on before removing the old battery
5 Turn the machine power off. Reboot the machine, and verify that the "A.83"
alarm has cleared.
6 Press the [READY ON] switch to turn on the servo (200V) power. If machine
status is normal, then the procedure is complete.
WARNING
Press EMERGENCY STOP before performing this procedure.
