A Abnormality during absolute encoder
memory check
• Follow absolute encoder set-up proce-
dures.
• Replace servomotor if error occurs fre-
quently.
B Circuit board (1PWB) defective Replace SERVOPACK.
Note An absolute encoder error (A.80) is given initially if a sum-check error (A.82) is generated
during operation.
The sum-check error (A.82) occurs after turning the SEN signal (or SERVOPACK power sup-
ply) OFF and back ON.
However, the sum-check error (A.82) does occur during operation if the host controller is re-
ceiving the S-phase signal (serial data).
