Hello I just buy a new CNC on ebay, that come with the HY01D523B when I plug the VFD to 220V. is doing this:
1.- Leds POWER FOR Hz A ROTT solid, and 6 0 in the display (this for about one second)
2.- Leds POWER FOR REV Hz A Solid, and in the display h (like in a mirror) and 0 (also one second)
3.-Leds POWER and HZ solid, Leds FOR and ROTT Flashing. In the displays 0 0

After that non of the buttons work i can push any of them and the step 3 is alway there.

Please some advice!
