Hi there, I have been trying to wrap my head around this for a few days now, I'm trying to get my fc300 VFD to go into reverse, I can go in and change to a different parameters but when I press enter I cant change the value at all, I thought it my be password locked but when I go to that parameter I cant change that as well, \nd the parameter that is supposed to be associated with telling it to be externally controlled.
I can send M commands from Mach 4 to it but the pin that's supposed to act as reverse just sends it the same direction.
Is there a a jumper pin that is set somewhere to keep it locked to external control or something I am missing?
My control board is a c25xp, and using ess configuration, the commands are activating the right pins and relays, but just cant get access to the VFD to allow the one pin to be reverse even though it is supposed to be by default.
Any help of advice would be greatly appreciated. This is a used unit so I don't know what the previous operator has done to it.
