★Reduce the voltage.
● Power supply waveform abnormal
★Replace the power supply.
● Servo driver failure
★Replace the servo driver.
In operation
●Circuit board failure
★ Replace the servo driver.
● Braking circuit failure
★Check the braking resistor.
Being enabled
● Main power supply voltage too low ★ Replace the power supply.
●Circuit board failure
★Replace the servo driver.
●Soft start circuit failure
★Replace the servo driver.
In operation
● transformer capacity insufficient
★Increase the transformer capacity.
●Power supply wire loose
★ Tighten wiring terminals
●Circuit board failure
★Replace the servo driver.
In operation
● Command speed too faster
★Reduce the command speed.
● Input voltage too low
★ Check R/S/T power supply.
● Parameter PA17 too small.
★Increase
the
parameter
appropriately.
●Wire loose
★ Check and tighten the wire.
Power on
● Motor damaged
★ Replace the motor.
● Sensor wire broken
★Check the wire and replace the
sensor.
In operation
●Motor power too small
★ Replace the current motor by a
high-power motor.
