Status and Remedy for Alarm
„ A.32
A.32: Regenerative Overload
Display and Outputs
Note: OFF: Output transistor is OFF (alarm state).
ON: Output transistor is ON.
Status and Remedy for Alarm
Cause Remedy
A Regenerative transistor is abnormal. Replace SERVOPACK.
B Disconnection of the regenerative
resistor. Replace SERVOPACK or regenera-
tive resistor.
C Regenerative Unit disconnected
(for an external regenerative resistor). Check wiring of the external regener-
ative resistor.
D SERVOPACK defective. Replace SERVOPACK.

Cause Remedy
A Regenerative power exceeds the allowable
value. Use an external regenerative resistor
that matches the regenerative power
capacity.
B Alarm occurs although an external regener-
ative resistor is used and the temperature
rise of the regenerative resistor is small. Correct parameter Pn600.
