Inputs—Enable, Reset
The drive Enable and Reset inputs are optically isolated inputs. Current is
limited internally for input voltage control of 5 to 24 volt logic. The Anode (+)
and Cathode (−) are on separate connector pins to allow significant flexibility
in wiring to different styles of interface.
