I have a MKS4-V board made by a chinese company called Cheng du Xing Cheng Technology Co. LTD. I have connected the 6 wires for controlling the spindle. It can control the spindle using the VFD panel control including the rpm. But I cannot control the spindle using Mach3. The spindle has no response when I click Spindle Cw F5 button on Mach 3 BUT the VFD fan turns on.

VFD model is MK100-2S1.5G-DK it's a 1.5kw made by a company called Nangtong Hui Automation Equipment Technology Co. Ltd.

Laptop is a 32 bit Windows 7

It could be some numbers in Configuration - ports and pins- output signals -- Output #1 (port# 1, pin # 14) incorrect.

Any help would be appreciated.
