Stepper Motor Driver Module

Figure 4.2.3

The control card allows you to connect up to three stepper motor drivers.
These connect your control card to the stepper motors, and supply them with electric power.
The drivers regulate the direction and speed of the stepper motors.

The stepper motor drivers are connected as follows:
Version 1: Drivers are supplied with power supply for the motors.
