George,

There may be a problem with the sequence of contacts. I tried something similar to this a while back.

The manual states: "Note: The Jog Command cannot be used when the motor is running. The motor must be stopped to initiate this command. ".

What I'm remembering was that if your jog button was pressed first it would use the jog speed reference. But if it received the run command first then what ever the speed reference was it would use that.

Edit: My newest manual says "Note: the motor must be stoped to initate this command. The jog command cannot be used simultaneously with an active FWD?STOP, REV/STOP command. The jog command can be used with an active REV/FWD command. " Page 4-25

If I'm remembering correctly I just used one of the preset speeds in combination with the reverse selection

I will try that and remember to post my results if anyone is interested.

George, please do.

A couple of things appear to be different between your application and mine. It looks like you are planning to 100% hardwire the controls and take advantage of the built in "3 wire scheme ". I was replacing a yaskawa with a GS2. I also had a PLC hooked up to the inputs and they were in the "2 wire mode ". In the Yaskawa the "jog " input took precedence over all other inputs except "Base Block ". So the PLC programming took advantage of that. When I fired up the GS2 it would not go into "jog " every time, quite a puzzler until I found the info on the GS2 "jog ".
