Cause
Remedy
A
Absolute encoder malfunctioned
•
When Cn-01 Bit 1 = 0, turn SEN signal OFF
and back ON.
•
When Cn-01 Bit 1 = 1, turn Servopack con-
trol power OFF and back ON.
•
Replace servomotor if error occurs fre-
quently.
B
Circuit board (1PWB) defective
Replace Servopack.
Note
No alarm occurs at the Servopack when a data error (
A.84
) is generated. The data error
(
A.84
) occurs the next time the SEN signal (or Servopack) turns ON.
However, the data error (
A.84
) can be read during operation if the host controller is receiving
the S-phase signal (serial data).
