Craig,
I’m not opposed to using the drives to close the loop, but there is a bit of rewiring to go that way . The outputs j2 thru j4 would have to be used on the 7766 as opposed to j8 which carries all step and direction as well as all encoder signals. J8 connects through a 24 pin cable to a 7737 encoder board which collects encoder signals and outputs step and direction signals through rj45 Ethernet cable connections. (It is the j8 circuitry that is activated with the closed loop purchase from VSI.) Without the use of j8 I’m not sure how to wire the encoders. Just simpler at my level to use the 7766, not saying that there isn’t a workaround for the encoder inputs, l just haven’t dug into it yet. It may be possible to output step and direction through j2 - j4 while collecting encoders through j8 thus not closings the loop in the 7766, but I don’t yet know that. As far as using the built in software scope, that has never displayed any motor information at all, are you suggesting that maybe that function only works with the 7766 in an open loop condition? That would be good news indeed.
Thanks for your interest and any input you have to offer is much appreciated,
Lou
