12 MP-Series Low-inertia Servo Motor with 215 mm or Larger Frame Size
Attach the Motor Cables
Follow these steps to attach the feedback and power/brake cables after the motor is mounted.
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.
1. If you are using the Threaded DIN (M4) Cable Plugs, install the O-rings.
An O-ring on the connector is necessary to achieve the maximum environmental rating.

Install the O-ring on the SpeedTec-ready DIN motor connector when
you are using the threaded DIN (M4) cable plugs.
Verify that the O-ring is not damaged, not twisted, and rests in the
groove near the rear of the connector.
Do not install the O-ring on the SpeedTec-ready DIN motor connector
when you are using the SpeedTec DIN (M7) cable plugs.
