12.2.18 Stepper Module
For the PI configuration for the stepper module, there is one module type
available:

Description
Proxy I/O modules
STEPPER
Stepper Controller, Stepper Servo
75x-670, 75x-671, 750-672, 750-673
The stepper controller is used to control different drive power sections with
pulse/direction interface or incremental encoder input. RS-422 and 24V or 20 mA
interfaces can be used.
The stepper servo has its own power stage and incremental encoder evaluation
for controlling 2-phase stepper motors.
The following table lists the number of bytes reserved for the module in the
respective process image (PI).
