Power Section

The power stage generates drive currents from the pulses for the specific
motor. Any type of output stage equipped with a pulse direction or
incremental encoder interface can be used with the 750-670 stepper module
This also allows output stages for 3- or 5-pole stepper motors, DC or AC
servo motors to be used. Stepper modules 750-671, -672 and -673 are
equipped with an integrated output stage for regulating 2-phase stepper
motors.

Drive

Stepper motors are simple and economical drives that execute highly precise
tasks for a wide range of applications.
The shaft of a stepper motor rotates by a defined angle at each pulse; a rapid
succession of pulses transforms the stepping motion into a continuous turning
motion. The stepper motor's natural resonance is suppressed largely by high-
revolution microstepping, which produces extremely smooth operation. This is
characteristic of WAGO modules 750-671, -672 and –673, which feature 64-
fold microstepping.
The figures below illustrate possible types of connections for stepper motors:
