Confirmation
Replace the part. Con-

Correctly connect a
jumper.
Correct the wiring of the
External Regenerative
Resistor.
While the main circuit
power supply is OFF, turn
the control power supply
to the SERVOPACK OFF
and ON again. If an alarm
still occurs, the SERVO-
PACK may be faulty.
Replace the SERVO-
PACK.
Set the power supply volt-
age within the specified
range.
Change the regenerative
resistance value or capac-
ity.
Reconsider the operating
conditions.
Reconsider the system
including the servo,
machine, and operating
conditions.
Correct the setting of
Pn600 (2600 hex).
Correct the setting of
Pn603 (2603 hex).
Change the regenerative
resistance to a correct
value or use an External
Regenerative Resistor of
an appropriate capacity.
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
