from the tables on page 59

Velocity, position, and acceleration counts per unit are based on the selected User

Units (mm or in.).

User Unit Scaling Parameters

(1)

(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-V20xxx is 20 mm/rev. MP-

Series Integrated 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.
