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.
Encoder cable: For best shielding use cable with an overall shield and individual shields on twisted
pairs, connect the cable as illustrated in Figure 4-6. Clamp the overall shield to grounded metallic
surfaces at both the encoder and the drive.
Brake resistor cable: The optional braking resistor should also be wired with shielded cable. If
unshielded wire is required refer to the Unidrive M700 / M701 User Guide for guidance.
Control cables: If the control wiring is to leave the enclosure, it must be shielded and the shield(s)
clamped to the drive using the grounding bracket. Remove the outer insulating cover of the cable to
ensure the shield(s) make contact with the bracket, but keep the shield(s) intact until as close as
possible to the terminals.
