Hi everyone. I have a problem with G120 drive. I setup DI 1 parameter value as P1113. Problem is that: when i connect computer with installed Starter, the revers working fine. But when i disconnect computer revers disappears.

Can someone explain me what magic is here ? 

Hi,

what do you mean with "when I connect the drive to the computer with Starter"? Do you mean you are going online with your Starter project to the drive?

And then the switching of the speed setpoints works via the DI? And if you go offline the switching does not work anymore with the DI?

Did you maybe download the project but forgot to save Ram to Rom and restarted the drive?

Yes, i mean that when Starter online the revers is working. But without connection it's not working. 

Yes i am switching DI1. It works only when Starter is online, and doesnt without it.

I save the project in drive with coping Ram to Rom, twice. But it doesnt work.

Problem solved. The reason was that we didn't connect the GND of the drive with the GND of the external power supply, but somehow the connection did occur when the Starter was online.

New question published by last85 is split to a separate thread with the subject How to prohibit the reverse on the run?.
