how can set the parameters?

Dear AV1234,

basically it is not realized in the standard configuration to start and stop a G120 only with a impulse and two DI's. Please check chapter 8.5 of the instruction maual of the G120. There are some makros shown how to control a drive with only 2 or 3 signals.

To get your requested functionalitiy please use the free function blocks of the G120. For example you can use a RS-flipflop and connect it with the ON/OFF signal (p840) of the G120. As setpoint you can use the fixed setpoint in p1001 for example.

Hi 

I prepared this some time ago, it provides 'Momentary Contact Start, and also a switch between Command Data Sets 0 and 1. 

I have indicated the bits required for momentary contact start.

Have a look and come back if I can help further.
