Solution
★Replace the driver.
★Check whether internal enable
★ Check the wire of the motor.
★Motor encoder zeroing
★ Restore the parameters
★Check that there is no water in the
motor connector.
★Reduce the command speed.
★Adjust the acceleration/deceleration
constant.
★Reduce the load.
★Reduce the voltage.
★Replace the power supply.
★Replace the servo driver.
★ Replace the servo driver.
★Check the braking resistor.
★ Replace the power supply.
★Replace the servo driver.
★Replace the servo driver.
★Increase the transformer capacity.
★ Tighten wiring terminals
★Replace the servo driver.
★Reduce the command speed.
★ Check R/S/T power supply.
★Increase
the
parameter
appropriately.
★ Check and tighten the wire.
★ Replace the motor.
★Check the wire and replace the
sensor.
★ Replace the current motor by a
● Motor interface short circuited
high-power motor.
★Take waterproof and dustproof
In operation
● Servo parameters incorrect
●transmission partially jammed
●Load too great
●Motor failure
measures.
★Match a right motor model.
★ Disconnect the mechanical part.
★ Reduce the load
★Replace the motor.
