The direction of rotation of the motor can either be changed by swapping
the ± connections at the differential input, or by means of a logic input or by programming.
The analog inputs can be assigned to different functions.
With a digital command value (RS232, x-bus)
- the analog input AIN1can be programmed as external analog speed limit
- and the analog input AIN2 can be programmed as external analog current limit.
