Controlling a VFD that accepts 4-20ma input

Barnhart Crane 8 months ago updated 8 months ago 2

I want to use an IQAN MC43 to control a VFD. The VFD can be controlled by either a 4-20ma signal or a 1-10v input.

What would be the best way to do this using an MC43? Doesn't seem to be too many CANOpen to 4-20 ma devices that I can find.

I have used Seneca ZC3AO unit many times- canopen to 3 off independent analogue outputs which can be voltage or current and scaled as required

Thank you. This is exactly the kind of device i was looking for.
