UC300 and YL620 VFD problem

I'm trying to connect the UC300 to the LY620 VFD, and I'm having problems starting the spindle, and if it's already working, then the speed can't be controlled.
Thank you if you can help me.
The VFD is configured correctly and works great with another CNC controller.
Tank you.

This VFD in this configuration works great with another CNC controller.
The problem as I see it is that when I run the SPINDLE at a speed of 24000 I measure 10V at the VSO port of the UC300 controller. If I try to lower the speed even to 20000 the voltage drops to 0, only at 24000 there is voltage at this port.
Maybe something in the MACH3 settings.

Follow this thread looks like you need to make sure you program the PWM spindle parameter as mentioned in this thread.
