4.7.3 Battery Replacement
If the battery voltage drops to approximately 2.7 V or less, an absolute encoder battery error alarm (A.830) or
an absolute encoder battery error warning (A.930) will be displayed.
If this alarm or warning is displayed, replace the batteries using the following procedure.
Use Pn008.0 to set either an alarm (A.830) or a warning (A.930).
• If Pn008.0 is set to 0, alarm detection will be enabled for 4 seconds after the ALM signal outputs max. 5 sec-
onds when the control power is turned ON.
No battery-related alarm will be displayed even if the battery voltage drops below the specified value after
these 4 seconds.
• If Pn008.0 is set to 1, alarm detection will be always enabled after the ALM signal outputs max. 5 seconds
when the control power supply is turned ON.
(1) Battery Replacement Procedure
Using an Encoder Cable with a Battery Case
1. Turn ON the control power supply of the SERVOPACK only.
2. Open the battery case cover.
