Resistor or a Regenera-
tive Resistor Unit is con-

Correction
Connect an External
Regenerative Resistor, or
set Pn600 (Regenerative
Resistor Capacity) to 0
(setting unit: ×10 W) if no
Regenerative Resistor is
required.
Connect an External
Regenerative Resistor and
set Pn600 to an appropri-
ate value, or connect a
Regenerative Resistor
Unit and set Pn600 to 0.
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.
