Attach the Motor Cables
Follow these steps to attach the feedback and power/brake cables after the motor is mounted.
1. Verify the seal and O-rings are installed as shown in the diagram.
An O-ring on the feedback connector, and a backshell seal on the feedback and
power/brake connector, is necessary to achieve the maximum environmental rating.
ATTENTION: Servo drive power must be turned off before connecting or disconnecting the cables to the motor, and
if a cable is left disconnected at the motor end.
Arcing or unexpected motion can occur if the feedback, power, or brake cables are connected or disconnected while
power is applied to the servo drive.
ATTENTION: Be sure that cables are installed and restrained to prevent uneven tension or flexing at the cable
connectors. Provide support at 3 m (10 ft) intervals throughout the cable run.
Excessive and uneven lateral force at the cable connectors can result in the connector’s environmental seal opening
and closing as the cable flexes, or wires separating at the cable gland.
• A backshell seal covers the joint inside the feedback and
power/brake housings. It seals the joint between the
backshell and the housing of the connector.
• Verify that the backshell seal is not damaged, and it is
fully seated against the face of the backshell.
