Beta versions did not have a fault pin, but do have an led that signal a
fault and the drive also disconnects until an automatic reset in 5 seconds.
The fault occurs if actual position is > 114 counts from commanded if I
remember correctly. It is my understanding that the production units will be
bringing this fault signal to a terminal so you can feed it back to the
controller program to shut down on fault.
I have no idea on the cooling, but when I had asked Mariss about a drive I
had that was running very hot the answer seemed to indicate that additional
cooling is not required and he gave me some things to look at in my setup
that could be causing hot running. Ended up it was my fault and I was
mistakenly running 24 v motors on a 72 v supply. When I dropped back to a 36
v supply everything was fine temperature wise.
