A.330:
Main Circuit
Power Supply
Wiring Error
(Detected when
the main circuit
power supply is
turned ON.)
The regenerative
resistor was discon-
nected when the
SERVOPACK power
supply voltage was
high.
Measure the resistance
of the regenerative
resistor using a measur-
ing instrument.
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.

DC power was sup-
plied when an AC
power supply input
was specified in the
settings.
Check the power sup-
ply to see if it is a DC
power supply.
Correct the power supply
setting to match the
actual power supply.
*1
AC power was sup-
plied when a DC
power supply input
was specified in the
settings.
Check the power sup-
ply to see if it is an AC
power supply.
Correct the power supply
setting to match the
actual power supply.
Pn600 (Regenerative
Resistor Capacity) is
not set to 0 and an
External Regenerative
Resistor is not con-
nected to one of the
following
SERVOPACKs:
SGD7S-R70A, -R90A,
-1R6A, -2R8A, -R70F,
-R90F, -2R1F, or
-2R8F.
Check to see if an
External Regenerative
Resistor is connected
and check the setting of
Pn600.
Connect an External
Regenerative Resistor, or
if an External Regenera-
tive Resistor is not
required, set Pn600 to 0.
*1
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
