I briefly looked at the manual. It looks like the only user option is a
switch array for the current limit and microstep setting. So, type 0,
(step/dir) should be the proper stepgen type.
I would try wiring driver separately from EMC2. Wire the inputs as shown
on page 14 at the bottom. Just run a wire from a 5 Volt source to the
OPTO pin, then run each input pin to a switch then to ground (,or just
use the wire as a switch). To be safer put a 300 Ohm resistor inline
with each input wire to limit the current to 16 mA going through each
input pin. There should be a limit resistor already installed inside the
driver, but this makes sure. So you have:
OPTO ---> +5 Supply
PULSE --> wire to switch then supply ground, flipping switch moves motor
DIR ----> wire to switch then supply ground, switch changes direction
AWO ----> wire to switch then sply gnd, switch on disables motor output
RDCE ---> wire to sw then sply gnd, changes high or low current to motor
/
INPUT --/\/\--------o/ o----Ground
Resistor Switch
I may have the switch position wrong, so try AWO in both positions. Then
Cycle PULSE with DIR in one and then the other position. If this works,
and Stepgen set to type 0, then most likely the EMC2 dir signal is not
getting to your drive properly.
