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 Sensor ON command is changed from ON to OFF.
Note: The Sensor ON command cannot be turned OFF while the servomotor power is ON.
Output example of alarm contents are as shown below.
