Wiring the 220 spindle coolant pump?

I purchased a 220 volt spindle and they sent a 220 volt pump with it. Can I wire in the pump in the same location as spindle in the vfd so it comes on at the same time. If so will it control speed of pump as the spindle Rpm changes? I’m sure it is not that simple. I just would like the pump to run when spindle does .

NO you can’t. Use an SSR

In my case I used the multi-output of HY Huanyang VFD as input voltage when I use the spindle.

HY Huanyang VFD have an internal circuit and configurable option that can be use to control external device like IOT or SSR.

You can refer to my post in the forum for more information about wiring. Ref ( https://forum.onefinitycnc.com/…/information-to…/2647… ).

Wiring needed (refer to the diagram)

  • Connect HY pin +24v to HY pin FB
  • Connect HY pin FC to + connector of your IOT
  • Connect HY pin DCM to – connector of your IOT

Configure VFD (tell the vfd to trigger multi-output when spindle run)

  • PD052 SET 2 SET [DEFINE Multi-Output 3(FA, FB, FC function)]
  • PD053 SET 1 SET [DEFINE Multi-Output 4 (KA, KB function)]

Other reference for ssr but use differente pinout. ( How to use an SSR (Solid State Relay) )

Thank you for your complete response. im guesing an IOT and an SSR are same thing. the fact that i am 220 volts for spindle and the coolant pump.
you really are something to hhave taken the time with this .
Thank you,
I do not have a 3d printer was wondering if you did the printing as well. if so please let me know the costs involved.

Sorry I don’t have printed version. The ssr act as a switch on the high voltage side. The low voltage side is trigger by the vfd.

You can buy ssr that have kind of a small case like this one and just wire your pump on one side (split only one cable of the 220v power cord).
