For the control wiring, you also want to look at page 13.
- Pins AI1 - AI3 (page 17) are the analog inputs for your 0-10V speed signal - unless you can generate a +/-10V signal you should use AI3. There's also a 10V supply on "10V" if you need to provide that to your controller or want to use an external potentiometer.
- The "multiple functional digital inputs" G24 and X1 - X8 are used for the "enable", "direction" or "FWD" / "REV" signals from your controller. You have to tell the VFD what functions you are wanting for those. The various schemes are shown on page 55 and 56 (their page numbers).
- Some VFDs have an 24Vdc power supply inside the VFD but some don't, in which case you'd have to provide your own 24Vdc power supply. This product says it "offers the user" 24V at 150mA on pin "P24" / "XC", which keeps life simple. This is a safe low voltage output ie not connected to mains, as are the digital inputs and the 10V analog input.
