Welcome.
I try connected of the water pump to the VFD huanyang. The pump is a simple aquarium pump powered from 230V AC. How to connect pump to VFD to start at the same time what spindle? Do I need extra electronics?
Sorry for my English
Yours!

You will need to configure one of the extra outputs on the VFD to switch on/off with the spindle. That output should switch an external relay to power your pump.

Four outputs possible.
It looks like PD050 default is set for ON when a run command is on, this is a solid state open collector, same as PD051, if you want relay output, set either relay output PD052 or PD053 to 01 then one of these will be on when in run.
You could pick up a higher rated relay to operate the pump, or even an SSR.

Thank you for your suggestions. We managed to run the system. Parameters PD050, 051, 052, 053 changed to "1" and used a 24V source and connectors FA, FB and FC. I joined the relay coil to 24V and everything works as expected

An old post, but on the Huanyang I have the N.C. and N.O. contacts (FA,FB,FC) on the output relay are opposite to the user manual that came with it.

Old thread, but same issue. I have a 12v pump that I want the VFD to trigger a relay to switch the pump on when the spindle runs. I am running a gecko drive and a 48v power supply with the CNC. I will use a separate power supply for the pump. After setting relay output PD052 or PD053 to 01, how do I energize the coil on the relay?

[Al_The_Man]

On mine, I only have PD050 or PD51 which is the open collector pair, the PD052 is the N.C./ N.O. option of the mechanical relay.
Whether using the FB/FC internal relay or the either of the two open collector transistors, you will need to supply a voltage in order to pick up your relay of choice.
With the open collector type you will need a low voltage DC relay. With the relay type output you could use a N.O. contact to switch direct, but I would advise using a external relay also on these to avoid damaging the internal relay.
In this case the relay type and voltage is fairly open as it is just internal contact closure.
You could use the 12vdc pump supply to also supply the relay.
