Re: Driving coolant pump with VFD
There are two ways to do it, the FA/FB are N.O./N.C contact with FC being common and will switch 3a @ 250v, so any AC/DC relay would work with the right supply/coil voltage.
The other is to apply a function to the transistor outputs DRV UPF, these are open collector 24vdc max at 100ma so this could also be a 24vdc relay coil.
