I just zero mine along with the rest as theres no home switches on my toy. 2 more mouse clicks. > I am going with Automation Direct for the servo and drive, > http://www.automationdirect.com/adc/Shopping/Catalog/Motion_Control/Se >rvo_Systems/Medium_Inertia_(1KW_-_3KW)_Servo_Systems/3KW_Servo_System_( >Med_Inertia)/SVA-2300 . Using the servo with no brake. In that event, I'd tie those signals to control the hydraulics to those signals from motion that you quoted. Hardware details are up to you, like how to control the valves that do the lock/unlock of the table. Thats an open collector signal on pin 21? Both on the same interface pin strongly suggests it is, so that it can be read as an input also.
