Do not work with the Servo Motors unless the power is disconnected from the machine. The
servomotors are run by 110 VAC. There is possibility of death by electrocution!
1. Turn off power to the machine.
2. Each motor is mounted by the use of (4) ¼ - 20 screws. Be careful not to over tighten
these bolts and strip the threads.

WARNING!
Do not work with the Servo Drivers unless the power is disconnected from the machine. The
servo drivers are run by 110 VAC. There is possibility of death by electrocution!
The Servo Driver for each axis is integrated into the servo motor casting.

Always engage (push in) the Emergency Stop switch, turn the ProtoTRAK SM Control off, and
disconnect the servo motor/driver cable at the cable breakout box.
1. Press in the Emergency Stop.

5. Reinstall the new servo driver with its heat sink plate. Be certain the gasket properly
seals the assembly.
6. Reinstall the motor/driver assembly. Make certain the belt is tight so that there is little
play if pinched in the middle.
