PID Control for DL06 or GS drive

[Dr. Kindorf]

I have a project where I need to control water pressure by using a VFD and Transducer for the pump. I have used the Koyo PLCs and GS drives extensively, but I one thing I haven't had the occasion to program with either a Koyo PLC or a GS Drive is a PID control. As you know there is always a little learning curve writing a PID operation for different models of equipment, and I have to get this up and running fairly quickly. Would anyone perhaps have a PID routine for this type of control written up for either of these they wouldn't mind sharing? I have a PLC that I will be used for control and signaling, so the function can either be in the drive or the PLC. Thanks...

DIrectsoft 5 has a wizard to setup the pid loop. Go PLC -> Setup -> Pid For pump pressure it's very easy to setup the parameters. When online with a plc then you can go View ->Pid View. It will open up a window to tune the parameters to make the pid loop work to your liking (hopefully ;) )
