Maximum Axis Speeds
Maximum axis speeds are limited by the CNC interface boards ability to
decode resolver feedback and convert it into encoder A quad B feedback.
The maximum motor RPM when set for 32768 counts/rev is 3000 RPM.
Actual final axis speed is based on gearing and lead screw pitch.
Exceeding this motor speed can result in feedback overflow on the CNC
interface board and a feedback error will be generated.
Connecting Resolver Feedback
Resolver feedback is wired directly from the motor mounted resolver to the
CNC wiring board found in the system module. This cable can be
purchased directly from Allen-Bradley (cat no 1326-CCU-xxx).
