Hello,
I have a drive running a roller which is winding a textile material. The speed is controlled by the tension of the textile before the roller. I have to provide a switch by which the operator can change the winding direction (CW or CCW).
When I connect to the drive with WinBass, I can see that this tensioning value (potmeter) is connected to input 2 of the ramp function generator RFG. However, I do not know where is the value at input1 is comming from.
When there is no material on the roller, it starts spinning and the speed goes up to 100%, also the value at input1 of the RFG is 100%.
If I modify the textile tensioning value (rotate the poti) the speed is reduced (also the value in input1). If I put a thick in the "change polarity" box, the roller turns the other way, however, if I modify again the tensioning value, there is no reaction, the roller is still rotating at full speed.
What should I do to be able to change the rotational direction and the speed would react if I modify the tensioning value?
