(1) User units are determined by the screw lead of the linear stage. The screw lead is defined in linear units of travel per revolution. For example, the travel per revolution of an MPAS-xxxxxx-V05xxA is 5 mm/
rev and that of an MPAS-xxxxxx-V20xxA is 20 mm/rev. MP-Series linear stages with a ball screw use a feedback device that provides 128 sin/cos cycles per revolution of the motor. The Ultra3000 drive
interpolates this signal by an additional 1024, causing the maximum count per internal motor revolution of the linear stage to be 131,072 counts/rev.
