Hi I would like to set up one of these drives to work off an Danfoss MBS 3000 4-20ma transmitter/ range of 0-10 bar. I have been going through some of the parameters of the PLC an have had no luck with the drive responding to pressure. it is just continuing to run ant parameter 202 low fz limit. Any with experience with these drives point me in the right direction I would be very grateful! Thanks Phil

Yep, setting up a VSD can be a real p.i.t.a - all it takes is one incorrect parameter or interlock and the thing won't want to know you.

Unfortunately I haven't used a 2800, often the HVAC VLT for me..

Usually I connect a signal generator to the VSD for the purposes of getting the parameters right, that way I can push the signal around at my desire.
