1) Failure of servo driver (failure of the
circuit, IGBT or other components)
2) Short of the motor wire (U, V and W)
3) Earth fault of the motor wire
4) Burnout of the motor
5) Poor contact of the motor wire.
6) Welding of contact of dynamic braking
relay due to frequent servo ON/OFF
operations.
7) Timing of pulse input is same as or
earlier than Servo-ON.
8) Blowout of thermal fuse due to
overheating dynamic brake circuit.
(Only F and G frames)
1) Turn to Servo-ON, while disconnecting the
motor. If error occurs immediately, replace
with a new driver.
2) Check that the motor wire (U, V and W) is
not shorted, and check the branched out
wire out of the connector. Make a correct
wiring connection.
3) Measure the insulation resistance between
motor wires, U, V and W and earth wire. In
case of poor insulation, replace the motor.
4) Check the balance of resister between
each motor line, and if unbalance is found,
replace the motor.
5) Check the loose connectors. If they are, or
