4.7 Absolute Encoders
4-47
(4) Transferring Alarm Contents
If an absolute encoder is used, the contents of alarms detected by the SERVOPACK are transmitted in serial
data to the host controller from the PAO output when the Turn Encoder Power Supply OFF command
(SENS_OFF) is received.
Note: The SENS_OFF command cannot be received while the servomotor power is ON.
Output example of alarm contents are as shown below.
