The setting of Pn603
(Regenerative Resist-
ance) is smaller than
the capacity of the
External Regenerative
Resistor.
Check to see if a
Regenerative
Resistor is con-
nected and check
the setting of Pn603.
Correct the setting of
Pn603.

The external regener-
ative resistance is too
high.
Check the regenera-
tive resistance.
Change the regener-
ative resistance to a
correct value or use
an External Regen-
erative Resistor of an
appropriate capacity.

(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 resist-
ance of the Regener-
ative Resistor using
a measuring instru-
ment.
If you are using the
Regenerative
Resistor built into the
SERVOPACK,
replace the SERVO-
PACK. If you are
using an External
Regenerative
Resistor, replace the
External Regenera-
tive Resistor.

DC power was sup-
plied when an AC
power supply input
was specified in the
settings.
Check the power
supply to see if it is a
DC power supply.
Correct the power
supply setting to
match the actual
power supply.

Pn600 (2600h)
(Regenerative
Resistor Capacity)
(setting unit: 10 W) is
not set to 0 and an
External Regenerative
Resistor is not con-
nected to one of the
following SERVO-
PACKs: SGD7S-
R70A, -R90A, -1R6A,
-2R8A, -R70F, -R90F,
-2R1F, or - 2R8F.
Check to see if an
External Regenera-
tive Resistor is con-
nected and check
the setting of Pn600
(2600h).
Connect an External
Regenerative
Resistor, or if an
External Regenera-
tive Resistor is not
required, set Pn600
(2600h) to 0.
