SERVOPACK.
regenerative resistor is required.
The jumper between the
power supply terminals B2
and B3 is removed.
Confirm that a jumper
is mounted between
the power supply
terminals B2 and B3.
Correctly mount a jumper.
The external regenerative
resistor is incorrectly wired,
or is removed or
disconnected.
Check the external
regenerative resistor
connection.
Correctly connect the external
regenerative resistor.
A SERVOPACK fault
occurred.
While the main circuit power supply
is OFF, turn the control power
supply OFF and then ON again. If
the alarm still occurs, the
SERVOPACK may be faulty. Replace
the SERVOPACK.
The power supply voltage
exceeds the specified limit.
Measure the power
supply voltage.
Set the power supply voltage within
the specified range.
Insufficient external
regenerative resistance,
regenerative resistor
capacity, or SERVOPACK
capacity. Or, regenerative
power has been
continuously flowing back.
Check the operating
condition or the
capacity using the
capacity selection
Software SigmaJunma-
Size+, etc.
Change the regenerative resistance,
regenerative resistor capacity, or
SERVOPACK capacity. Reconsider
the operating conditions using the
capacity selection software Sigma-
JunmaSize+, etc.
Regenerative power
continuously flowed back
because negative load was
continuously applied.
Check the load applied
to the servomotor
during operation.
Reconsider the system including
servo, machine, and operating
conditions.
The setting of parameter
Pn600 is smaller than the
external regenerative
resistor's capacity.
Check the external
regenerative resistor
connection and the
value of the Pn600.
Set the Pn600 to a correct value.
The external regenerative
resistance is too high.
Check the regenerative
resistance.
Change the regenerative resistance
to a correct value or use an external
regenerative resistor of appropriate
capacity.
A SERVOPACK fault
occurred.
The SERVOPACK may be faulty.
Replace the SERVOPACK.

The regenerative resistor
disconnected when the
SERVOPACK power supply
voltage was high.
Measure the resistance
of the regenerative
resistor using a
measuring instrument.
When using a regenerative resistor
built in the SERVOPACK: Replace
the SERVOPACK. When using an
external regenerative resistor:
Replace the external regenerative
resistor.
In the AC power input mode,
DC power was supplied.
Check the power
supply to see if it is a
DC power supply.
Correct the settings to match the
actual power supply specifications.
In the DC power input
mode, AC power was
supplied.
Check the power
supply to see if it is an
AC power supply.
Correct the settings to match the
actual power supply specifications.
Regenerative resistor
capacity (Pn600) is not set
to 0 even though the
regenerative resistor is
disconnected.
Check if regenerative
resistor is connected
and check the
regenerative resistor
capacity.
A SERVOPACK fault
occurred.
The SERVOPACK may be faulty.
Replace the SERVOPACK.
