1.
Use the cable with shielding (double shielding is the best).
2.
The shielding on both ends of the motor cable should be grounded with the minimum length
and maximum contact area.
3.
Remove any paint on metal saddle for good ground contact with the plate and shielding.

The length of motor cable
When motor is driven by an AC motor drive of PWM type, the motor terminals will experience surge
voltages easily due to components conversion of AC motor drive and cable capacitance. When the
motor cable is very long (especially for the 460V series), surge voltages may reduce insulation
quality. To prevent this situation, please follow the rules below:
