Install
Installation of a new servo motor requires a careful alignment procedure, described
in the following steps. Failure to follow the alignment procedure can cause prema-
ture failure of mill components.
1. If not already installed, install the servo coupling on servo motor shaft.
The proper distance between the motor face and the Y-axis servo coupling is 5 mm.
2. Torque to 2.03 nm (18 in-lbs).
You can use the 5 mm Allen key as a spacer to set the coupling on the motor shaft.
