Alarm Number:
Possible Cause
Alarm Name
The power supply
voltage exceeded the
specified range.
The external regener-
ative resistance value
or regenerative resis-
tor capacity is too
small, or there has
been a continuous
regeneration state.
There was a continu-
ous regeneration state
because a negative
load was continu-
ously applied.
The setting of Pn600
(Regenerative Resis-
A.320:
tor Capacity) is
Regenerative
smaller than the
Overload
capacity of the Exter-
nal Regenerative
Resistor.
The setting of Pn603
(Regenerative Resis-
tor Capacity) is
smaller than the
capacity of the Exter-
nal Regenerative
Resistor.
The external regener-
ative resistance is too
high.
A failure occurred in
the SERVOPACK.

Confirmation
Measure the power
supply voltage.
Check the operating
conditions or the
capacity using the Sig-
maJunmaSize+ Capac-
ity Selection Software or
other means.
Check the load applied
to the Servomotor
during operation.
Check it see if a Regen-
erative Resistor is con-
nected and check the
setting of Pn600.
Check to see if a
Regenerative Resistor is
connected and check
the setting of Pn603.
Check the regenerative
resistance.

Correction
Set the power supply volt-
age within the specified
range.
Change the regenerative
resistance value or capac-
ity.
Reconsider the operating
conditions using the Sig-
maJunmaSize+ Capacity
Selection Software or
other means.
Reconsider the system
including the servo,
machine, and operating
conditions.
Correct the setting of
Pn600.
Correct the setting of
Pn603.
Change the regenerative
resistance to a correct
value or use an External
Regenerative Resistor of
an appropriate capacity.
The SERVOPACK may be
faulty. Replace the SER-
VOPACK.
