MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes 5 • Shaft seals are subject to wear and require periodic inspection and replacement. Replacement is recommended every 3 months, not to exceed 12 months, depending on use. Refer to Shaft Seal Kits on page 19 for more information. • Inspect the motor and seals for damage or wear on a regular basis. If damage or excessive wear is observed, replace the item.
MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes Using Couplings and Pulleys Mechanical connections to the motor shaft, such as couplings and pulleys, require a torsionally rigid coupling or a reinforced timing belt. The high dynamic performance of servo motors can cause couplings, pulleys, or belts to loosen or slip over time. A loose or slipping connection can cause system instability and damage the motor shaft.
MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes 7 Build and Install the Cables Correct cable routing and careful cable construction improves system electromagnetic compatibility (EMC). Follow these guidelines to build and install the cables: • Keep the wire lengths as short as possible. • Route noise sensitive wiring (encoder, serial, and I/O) away from input power and motor power wiring. • Separate cables by 0.3 m (1 ft) minimum for every 9 m (30 ft) of parallel run.

Verift that the power cable ground clamp on the drive contacts all (three) cable shields. Brake Control and Power Regulation The DC power source for a permanent magnet brake, such as that on the MP-Series servo motor with 75 mm (2.
MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes 9 Install the Motor MP-Series motors include a mounting pilot for aligning the motor on the machine. Preferred fasteners are stainless steel. The installation must comply with all local regulations and use equipment and installation practices that promote safety and electromagnetic compatibility.
MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes Mount the Motor Follow these steps to mount the motor. ATTENTION: Damage can occur to the motor bearings and the feedback device if sharp impact to the shaft is applied during installation of couplings and pulleys. Do not strike the shaft, couplings, or pulleys with tools during installation or removal. 1.
MP-Series Low-inertia Brushless Servo Motors with 75 mm or Smaller Frame Sizes 11 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.

Carefully align the flat surface on the feedback or the power/brake cable plug (shown in the diagram) with the flat surface on the motor connector. IMPORTANT The motor orientation shown is used to clearly show the alignment marker on each cable socket. The recommended motor orientation when installed positions the connectors at the bottom of the motor.
