I'm trying to configure my Nowandforever E-100 VFD to work with the Pokeys57CNC, but I don't see anywhere in the board specs where I can wire the VFD to receive this information. I'm currently using the GND and pin 17 on the galvanically-isolated I/O bus, but pin 14 (labeled spindle error input) doesn't seem to be what I need. The spindle won't run until I give the VFD a closed circuit in terms of spindle direction (i.e., I have to have this in order to control the spindle from Mach4). Am I missing something here? Do I need to use one of the on-board relays to give me Mach4 control over whether the spindle is engaged? If using a relay is necessary, what output pins are associated with the relay? And can I map that relay between the Pokeys57CNC and Mach4?
Help for a newbie is greatly appreciated.
Thanks!
