Dear friends,

I need your help to setup my cncusb controller card to control the VFD speed.
- Controller: USBCNC card (see picture)
- VFD: HY01D511B, 110V-110V, 1.5KW, 14A (Huanyang)
- Software: CNC USB (Planet cnc):
SW: 2.10.1204.201;
HS: 2012.02.10;
SN: 59665 DIY
The manual shows that this command "M S24000" should be put in MDI and apply to ENTER in order to get 5v between the GND and AVI but when I apply ENTER I still have "0" volts between GND and AVI. I connected everything well but nothing is happened.

I attach some pictures for your reference:

Thank you in advance
