Cause and
correction
Assumed cause Remedy Prevention
A short-circuit, line-to-ground fault,
contact failure, or insulation failure
occurred on the U, V, or W motor line.
If there is a short-circuit, line-to-
ground fault, or contact failure on the
U, V, or W motor line, correct the
connections. If the insulation
resistance between the U, V, or W
motor line and the ground line has
failed, replace the motor.
Confirm that the U, V, and W motor
lines are connected correctly.
The Servo Drive failed. Disconnect the motor lines and turn
ON the Servo. If this error occurs
immediately, replace the Servo Drive.
None
The relay for the dynamic brake has
been welded due to frequent Servo
ON/OFF operations.
Replace the Servo Drive. Do not start and stop operation by
frequently switching the Servo ON/
OFF.
Motor windings are burned out. Check the balance of the resistance
between the lines of the motor. If
resistance is unbalanced, replace the
motor.
Do not apply excessive load on the
motor.
The motor is not suitable for the Servo
Drive.
Check the model (capacity) of the
motor and the Servo Drive on the
nameplates. Replace the motor with a
motor that matches the Servo Drive.
Use 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.
Wait at least 100 ms after the Servo
has been turned ON, then input
commands.
