Dear all friends,
i have hyperterm powermax30
to connect THC (Proma SD) i need to connect the voltage terminals from the plasma somehow. in the powermax30 there is no "easy" connections
so here i need your help.
1. from where should i take the terminals?
2. what voltage i suppose to see between terminals? (+ and -)
if i understand correctly from the single line (attached files) the (+) terminal is J22, but i am not sure for the (-) and from where to take it.
3. how should i connect my Z axis to the THC SD to my board? in my board the PUL(+) and DIR(+) are shorten to 5V and in the Proma THC the STEP (-), DIR(-) are shorten to GND.
i attached pictures from the plasma, THC SD and SainSmart controller board
thanks a lot guys
best regards
ASAF
