320h:
Regenerative
Overload
The power supply
voltage exceeded the
specified range.
Measure the power
supply voltage.
Set the power supply volt-
age within the specified
range.
–
The external regener-
ative resistance value
or Regenerative
Resistor capacity is
too small, or there has
been a continuous
regeneration state.
Check the operating
conditions or the
capacity.
Change the regenerative
resistance value or capac-
ity.
Reconsider the operating
conditions.
*2
There was a continu-
ous regeneration state
because a negative
load was continu-
ously applied.
Check the load applied
to the Servomotor
during operation.
Reconsider the system
including the servo,
machine, and operating
conditions.
–
The setting of Pn600
(2600h) (Regenera-
tive Resistor Capacity)
is smaller than the
capacity of the Exter-
nal Regenerative
Resistor.
Check to see if a
Regenerative Resistor is
connected and check
the setting of Pn600
(2600h).
Correct the setting of
Pn600 (2600h).
page 6-55
The setting of Pn603
(2603h) (Regenerative
Resistance) is smaller
than the capacity of
the External Regener-
ative Resistor.
Check to see if a
Regenerative Resistor is
connected and check
the setting of Pn603
(2603h).
Correct the setting of
Pn603 (2603h).
page 6-55
The external regener-
ative resistance is too
high.
Check the regenerative
resistance.
Change the regenerative
resistance to a correct
value or use an External
Regenerative Resistor of
an appropriate capacity.
*2
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
–
330h:
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 mea-
suring instrument.
If you are using the
Regenerative 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.
page 6-12
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.
A failure occurred in
the SERVOPACK.
–
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
