basically all you need to run is
power in on l1,2,3 l21 l22 which you obviously have
emergency to sg 15 to 10 or 20
son to sg 5 to 10 /20
limits to sg 16 17 to 10/20
motor encoder plugged in
***also connect vdd to com pin 3 to 13 which enables internal 24v power supply to circuits ( pin 3 is going to be your +24v output to pin 10 of 2803a chip. sg pins 10 or 20 will be your 0v to pin 9 on chip)
all above on plug cn1b
-------------------------------
below are plug cn1a
step in (pp) dir in (np) pins 2 and 3
gnd (ov) pin 11
damn that took a while to write out. you owe me a beer! (if it works)
