Cause Remedy
A • Battery not connected
• Battery connection defective Check and correct battery connection.
B Battery voltage below specified value.
Specified value: 2.8 V.
Install new battery and turn SEN signal (or
SERVOPACK) ON.
C Circuit board (1PWB) defective Replace SERVOPACK.
Note No alarm occurs at the SERVOPACK when a battery error (A.83) is generated. The battery
error (A.83) occurs the next time the SEN signal (or SERVOPACK) turns ON.
However, the battery error (A.83) can be read during operation if the host controller is receiv-
ing the S-phase signal (serial data).
