Confirmation
Measure the resistance
of the regenerative
resistor using a measur-
ing instrument.
Check the power sup-
ply to see if it is a DC
power supply.
Check the power sup-
ply to see if it is an AC
power supply.
Check it see if an Exter-
nal Regenerative Resis-
tor is connected and
check the setting of
Pn600.

Correction
If you are using the regen-
erative resistor built into
the SERVOPACK, replace
the SERVOPACK.
If you are using an Exter-
nal Regenerative Resis-
tor, replace the External
Regenerative Resistor.
Correct the power supply
setting to match the
actual power supply.
Correct the power supply
setting to match the
actual power supply.
Connect an External
Regenerative Resistor, or
if an External Regenera-
tive Resistor is not
required, set Pn600 to 0.
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
