232 hex:
Built-in Brake
Relay Life Alarm
The service life of the
built-in brake relay
was exceeded.
–
Replace the part. Con-
tact your Yaskawa repre-
sentative for replacement.
–
300 hex:
Regeneration
Error
The jumper between
the Regenerative
Resistor terminals (B2
and B3) was removed
from an SGD7S-
1R9D, -3R5D, -5R4D,
-8R4D, -120D, or
-170D SERVOPACK.
Check to see if the
jumper is connected
between power supply
terminals B2 and B3.
Correctly connect a
jumper.
The External Regener-
ative Resistor is not
wired correctly, or was
removed or discon-
nected.
Check the wiring of the
External Regenerative
Resistor.
Correct the wiring of the
External Regenerative
Resistor.
A failure occurred in
the SERVOPACK.
–
While the main circuit
power supply is OFF, turn
the control power supply
to the SERVOPACK OFF
and ON again. If an alarm
still occurs, the SERVO-
PACK may be faulty.
Replace the SERVO-
PACK.
–
320 hex:
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
(2600 hex) (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
(2600 hex).
Correct the setting of
Pn600 (2600 hex).
The setting of Pn603
(2603 hex) (Regenera-
tive Resistance) 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 Pn603
(2603 hex).
Correct the setting of
Pn603 (2603 hex).
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.
