7i77 Question

I am just starting to configure my first 7i77 setup. I have a simple question.
While I was trying to use PNCConf I did not notice where the drive enable switches (the 4 and 5th that go with the analog outs) are configured. Where and how are those assigned, or are they automatically set up when the pwms for the analog outs are configured?

there are only two enables.
one for the 0-4 analogs
and one for the 5th

the 5th is set up that way so you could enable a spindle separately.

if you look in the x axis section :
# enable _all_ sserial pwmgens
net x-enable hm2_5i25.0.7i77.0.1.analogena

if you select an analog spindle use analog 5
