8.4.4 Replacing Batteries
The SERVOPACK will generate an absolute encoder battery alarm (A.83) when the battery voltage drops below
about 2.7 V. This alarm is output, however, only when the SERVOPACK power is turned ON. If the voltage
drops while the SERVOPACK power is ON, the SERVOPACK will not generate the alarm.
• Battery Replacement Procedure
1. Replace the battery with only the SERVOPACK control power supply turned ON.
2. After replacing the battery, turn OFF the SERVOPACK power to cancel the absolute encoder battery
alarm (A.83).
3. Turn ON the SERVOPACK power back again. If it operates without any problems, the battery replace-
ment has been completed.
If the SERVOPACK control power supply is turned OFF and the battery is disconnected (which includes
disconnecting the encoder cable), the absolute encoder data will be deleted. The absolute encoder must
be setup again. Refer to 8.4.5 Absolute Encoder Setup (Fn008).
