Shield connections

The following guidelines should be followed to ensure suppression of radio-frequency
emission and good noise immunity. It is particularly recommended that the guidelines for the
encoder cable be followed closely in order to avoid disturbance to the encoder operation from
electrical noise. Use the grounding bracket and grounding clamp supplied with the drive to terminate
the shields at the drive.
Figure 3-3 Grounding of signal cable shields using the grounding bracket
Motor cable: Use a motor cable with an overall shield. Connect the shield of the motor cable to the
ground terminal of the motor frame using a link that is as short as possible and not exceeding 50 mm
(2 in) long. A full 360 ° termination of the shield to the terminal housing of the motor is beneficial.
