I'm not sure what you're asking but a 36V motor uses 4 wires, from a reeiver, like the old Echostar 3600, or V-Box. The main two are for drivng the motor, the other 2 are listed as sensor and ground, the sensor, I would assume, is for counting and ground self evident.
When setting up my first motor I used a battery, out of a house alarm, to position the motor correctly, taking account of my true south compared to the satellite I was setting up on, a 3 degree variant. For this I used just the 2 motor wires.
You could use the same method to set up any hardware limits, on your motor, but for the software limits, on your receiver I should think you need to use all 4 wires.
