Anyone know of a way to piggyback these vfd's. I'm wanting to mount 4 spindles on my machine and run them all simultaneously. It would sure help if they all turn on with a master.

What VFD Drive do you have and yes it should be not problem to turn them all on at the same time, could be as simple as one Relay, I guess you are running at a set speed so that could be where there could be problems if you want to control the speeds, if you can set the speed in the drive and just auto turn on then that is quite simple to do

You can control speed(frequency) via Modbus by assigning each its own modus id.

Posting an update on my situation.

First great thread. I got very nice help from mactec54 on a new VFD running my lathe project. Found out a big mistake was to start the motor then put clutch on and had faults. Now starting with the clutch on it works fine.

I had a VFD on my mill and had a problem with the VFD faulting half the time when I switched it on. Attempted to change to a different VFD and was asking for help on that. THEN I got to thinking about what was wrong with the VFD on my mill. It was that I was starting the VFD first then switching the power on with a switch between the VFD and the motor. Took out the switch and let the VFD run the motor itself and it works fine. Goes to show the VFD should have full control of the motor with no switching between the VFD and motor.

I am shelving the new VFD for another day, don't need it.

I know it was dumb to have a switch between the VFD and the motor but that was the problem. Wouldn't have figured that out without this forum and this thread.

Thank You mactec54

Looking for some advice I have ordered a Huanyang HY04D023B 4.0kw VFD.
Would like to make sure the setting i have put together from this very helpful thread look correct.
My motor is a 2HP 230 volt 3 phase 5.2 amps 60HZ 3480 RPM Supply voltage is 240 single phase.
PD000= 0
PD001= 0
PD002= 0
PD003= 60
PD004= 60
PD005= 60
PD006= 2.5
PD007= 10
PD008= 230
PD009= 20
PD010= 8
PD011= 40
PD013= 8 for reset only
PD014= 15
PD015= 15
PD141= 230
PD142= 5.2
PD143= 4 poles
PD144= 3000
PD072= 60
PD073= 60

Any advise is welcome
Thank you for your time
Dan

Your numbers look Ok when using a VFD you can have a higher and lower Hz range if you need it, this will depend on what you are using your motor for, you have it set for a lower HZ RPM

You have PD011=40 minimum speed

PD073=60 should be 40 also
