Stepper Motor Closed-Loop Control. Incremental Encoder On Motor - Technosoft IDM240-5EI Technical Reference

Motor _
where:
No_steps – is the number of motor steps per revolution
No_µsteps – is the number of microsteps per step. You can read/change this value in the
"Drive Setup" dialogue from EasySetUp.
T – is the slow loop sampling period expressed in [s]. You can read this value in the
"Advanced" dialogue, which can be opened from the "Drive Setup"

6.13.5. Stepper motor closed-loop control. Incremental encoder on motor

The internal motor speed units are motor encoder counts / (slow loop sampling period). The
correspondence with the load speed in SI units is:
Motor
where:
No_encoder_lines – is the motor encoder number of lines per revolution
T – is the slow loop sampling period expressed in [s]. You can read this value in the
"Advanced" dialogue, which can be opened from the "Drive Setup".
