Solution
Driver power output
short circuit
Verify if there is short circuit
between UVW terminals, or
shorted to PG.
1. Make sure there is no circuit.
2. Make sure motor is not
damaged
Motor wiring error
Verify motor wiring
Reconnect motor wiring
IGBT module short
circuit
Disconnect motor output cable.
Then, enable servo driver to
check for overcurrent
Replace driver
Control parameter
anomaly
Verify if parameter exceeds
recommended range
Set parameter within
recommended range.
Control command
anomaly
Verify if command motion is too
acute
Modify control command;
use filter
