14 hex
0 hex Overcurrent
The current flowing through the converter
exceeded the specified value.
•
The Servo Drive is faulty (faulty circuit,
faulty IGBT part, etc.).
•
Disconnect the motor cable, and turn
ON the servo. If the problem
immediately recurs, replace the Servo
Drive with a new one.
•
The motor cable is short-circuited
between phases U, V, and W.
•
Check to see if the motor cable is
short-circuited between phases U, V and
W by checking for loose wire strands on
the connector lead. Connect the motor
cable correctly.
•
The motor cable is ground-faulted.
•
Check the insulation resistance between
phases U, V, and W of the motor cable
and the grounding wire of the motor. If
the insulation is faulty, replace the motor.
•
Motor windings are burned out.
•
Check the balance between the
resistance of each wire of the motor. If
resistance is unbalanced, replace the
motor.
1 hex IPM Error
•
The motor wiring contacts are faulty.
•
Check for missing connector pins in
motor connections U, V, and W. If any
loose or missing connector pins are
found, secure them firmly.
•
The relay for the dynamic brake has
been welded due to frequent servo
ON/OFF operations.
•
Replace the Servo Drive. Do not start or
stop the system by turning the servo ON
or OFF.
•
The motor is not suitable for the Servo
Drive.
•
Check model (capacity) of the motor and
the Servo Drive on the nameplates.
Replace the motor with a motor that
matches the Servo Drive.
•
The command input timing is the same
as or earlier than the Servo ON timing.
•
Wait at least 100 ms after the servo has
been turned ON, then input commands.
•
The resistance of the connected
External Regeneration Resistor is less
than the minimum allowable value.
*1
•
Connect an External Regeneration
Resistor whose resistance is more than
the minimum allowable value.

15 hex
0 hex Servo Drive
Overheat
The temperature of the Servo Drive
radiator or power elements exceeded the
specified value.
•
The ambient temperature of the Servo
Drive exceeded the specified value.
•
Improve the ambient temperature and
the cooling conditions of the Servo
Drive.
•
Overload
•
Increase the capacities of the Servo
Drive and the motor. Set longer
acceleration and deceleration times.
Reduce the load.
