7i76e spindle problem: It runs, but only after reconnecting ENA

Do you know what the exact wiring issue was? I am having this same problem and have tried endless combinations. I’m using a Altivar32 drive, but it’s as if the enable and direction switches on the 7i76e never switch off… I have to physically disconnect direction pin to get the drive to reactivate… Thanks!

Sorry, I don't remember exactly - I think some pins were incorrectly connected on the TB4 connector. But I do not remember exactly which ones.

If the ENA output is always on it may be the you have the polarity backwards.

Thanks so much for the help, that’s exactly what it was! I didn’t realise that was a possible issue. It’s all working perfectly now with m3, m4 going on the right direction. Thanks again!
