Cause and Assumed cause
correction
A short-circuit, line-to-ground fault,
contact failure, or insulation failure
occurred on the U, V, or W motor line.
The Servo Drive failed.
The relay for the dynamic brake has
been welded due to frequent Servo
ON/OFF operations.
Motor windings are burned out.
The motor is not suitable for the Servo
Drive.
The command input timing is the
same as or earlier than the Servo ON
timing.

Remedy
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.
Disconnect the motor lines and turn
ON the Servo. If this error occurs
immediately, replace the Servo Drive.
Replace the Servo Drive.
Check the balance of the resistance
between the lines of the motor. If
resistance is unbalanced, replace the
motor.
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.
Wait at least 100 ms after the Servo
has been turned ON, then input
commands.

Prevention
Confirm that the U, V, and W motor
lines are connected correctly.
None
Do not start and stop operation by
frequently switching the Servo ON/
OFF.
Do not apply excessive load on the
motor.
Use a motor that matches the Servo
Drive.
Wait at least 100 ms after the Servo
has been turned ON, then input
commands.
