Message -
value:
Drive object: All objects
Reaction: A_INFEED: OFF2 (NONE, OFF1)
SERVO: NONE (OFF1, OFF2, OFF3)
VECTOR: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: Time slice overflow on the Voltage Sensing Module.
Remedy: Replace the Voltage Sensing Module.

Message -
value:
Drive object: All objects
Reaction: A_INFEED: OFF2 (NONE, OFF1)
SERVO: NONE (OFF1, OFF2, OFF3)
VECTOR: NONE (OFF1, OFF2, OFF3)
Acknowledge: IMMEDIATELY
Cause: An error has occurred during the memory test on the Voltage Sensing Module.
Remedy: - check whether the permissible ambient temperature for the Voltage Sensing Module is being main-
tained.
