2G Generator - Replacing a Servo Motor

This article will address how to change a servo motor if a failure is suspected.

1. Switch the power to the 2G to the "OFF" position.
2. Loosen the 2 set screws securing the servo motor's shaft to the servo motor coupler. (Omit this setup for the axis servo motor.)
3. Disconnect both the power and the encoder plugs.
4. Loosen the two clamping screws securing the motor in its mount.
5. Slide the new motor into the mount, taking care to align the flat on the motor's shaft with one of the set screws on the servo motor coupler. (For the axis servo, take care to align the teeth of the Delron gear with the gear at the rear of the chuck assembly.)
6. Tighten both set screws securing the motor to the coupler.
7. Tighten the clamping screws securing the motor in its mount. Do not over tighten, as this coudl bind the motor.
8. Reconnect both the power and the encoder plugs.
9. Recalibrate the 2G after any servo motor replacement.
