Assumed cause
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.
Cause and The relay for the dynamic brake
correction 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.
Attached None

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.
