Overcurrent
The current flowing
through the converter
exceeded the
specified value.
•
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.
