Step mode and limit speeds

The Beckhoff stepper motor terminals can output approx. 125,000 steps per second and have a step angle of 1.8° or 200 steps/revolution.

Maximum speed of the Beckhoff AS2000 stepper motor

The maximum speed is 3,600 rpm if using a Beckhoff stepper motor from the AS2000 series with incremental encoder. In practice the maximum speed is limited by the design of the stepper motor.

Beckhoff stepper motors from the AS2000 series are usually used only for applications with nominal speeds of well below 1,000 rpm.
