(1) Short-circuiting of the motor output connector may cause the driver to fail.

●The motor output connector and the power line.
●The motor output connector and the motor output connector.

(2) Disconnection of the motor output line may cause the driver to fail.

●Disconnection of the motor output line cable.
●Loose connection of connector.

(3) When a large inertial load (motor rotor inertia x 5 or more)is operated at

high speed(rotational speed 20s

or more),regenerative energy will

generate and increase the power supply voltage,which can damage the driver.
Review the operating condition and make sure regenerative voltage will not
generate.
