VFD (Huanyang model) 24V output?

Does anyone know if the 24V output on the VFD applies voltage when the spindle turns on? I want to connect a 24V air solenoid to turn on air assist,

Not sure which model you have but it’s unlikely, the 12V or 24V output is there to power small connected accessories such as opto isolators.

The multi-output relays on the VFD can generally be configured to open / close on spindle run, here’s a manual for a common model of HuanYang

Thank you for the info. I will have to figure out how to drive a 24V relay to activate the 24V solenoid,
