I've got a 300 with Motionview that I'm going to run using the IOD connector with discrete signals. First time to touch one of these. I see the pin 29 is enable/inhibit. I've tried +24VDC, 0v, and nothing and the drive will never 'enable'. What am I missing? I've got the the STO where the safety1 & 2 inputs are tied to +24VDC and the commons shorted together. I tried unshorting the commons. I tried removing the connector altogether. I've read the manual, there nothing mentioning 'enabling' other than that pin 29 being high, which obviously doesn't work for me. Any help?
