The enable signal to power-up the motor is issued with digital input 0
Further options: The enable signal can be issued with any other digital input, e.g. with
digital input 3 via P0704 = 1
CW rotation is activated with digital input 1
Further options: CW rotation can be activated with any other digital input, e.g. with
digital input 3 via P0704 = 2
CCW rotation is activated with digital input 2
Further options: CCW rotation can be activated with any other digital input, e.g. with
digital input 3 via P0704 = 12
