When the Step+ button is pressed, the stepper motor starts
to turn. The direction depends on the wiring of the motor

motor shaft). It thereby increases its rotational speed step by
step.

the opposite direction.

outputs, displays and buttons are then without function. The
motor current is switched off. After releasing the button, the
SEC−ST is reinitialized and the motor is energized again.
Please note

active until you press the Reset button (or switching the
SEC−ST off and on again).
