Hello all
I'm working on connecting a mesa 7i76e to a delta VFD e series. This is what I've got so far and I'm hoping for some help confirming I'm on track. Also is it ok to connect direct to the mesa or should I be using relays?

Thanks

7i76e DELTA VFD-E
TB4 pin 1 - ACM
TB4 pin 2 - AVI
TB4 pin 3 - 10V
TB4 pin 4 - not used
TB4 pin 5 - MI2
TB4 pin 6 - MI1
TB4 pin 7 - MI2
TB4 pin 8 - MI1

Field Power DELTA VFD-E
TB1 pin 8 - DCM
TB1 pin 5 - 24v

Parameter 04.04 must be set to:

1: 2-wire: FWD/REV, RUN/STOP

There should be no connection to the VFDs +24V terminal
There should be no other connection to DCM other than TB4 pins 5 and 7
(this wiring is for NPN mode)

PCW,

how about interfacing the Delta VFD-E to a SPIX1 board?

Basically the same except the VFD is set to FWD/REV mode
and you need to setup PWM on the host

PCW thanks,
pwm on the host is easy...so is setting the FWD/REV mode.

I'm not clear with the DCM, MI1, MI2, etc connections to the SPIN board.

or with how/what the CCW+-, CW+-, and ENA+- works.

so like this?

CCW+ >> MI2
CCW- >> DCM
CW+ >> MI1
CW- >> DCM
ENA+ >>>>>>>>>>> ?????? no connect?
ENA- >>>>>>>>>>> ?????? no connect?
