Hey all,
We are trying to interface a CompactLogix L35E with a Parker 590 DC Drive.
My main question is, can we connect the common from the VFD control board (pin A1, B1, or C1) to our 24VDC common? I've attached a couple connection diagrams from the VFD manual for reference.
If we can, we would be able to power the start (C3) and enable (C5) directly from our relay output card (1769-OW16) using our 24V supply without the need of interposing relays.
We will also be controlling Speed Setpoint (A4) which I have no idea how we would do without connecting commons. We are using a 1769-IF4OF2F (both AI and AO) card to control and monitor speed.
Any help would be greatly appreciated.
