Struggling JMC servo alarm wiring

[Andygraphy]

Hello,

i`am confused how to wire the alarm port (ALM-,ALM+) on my JMC (iHSV57) servos with the acorn controller. A friend made a shematic but i don`t know if this work or could damage my board.What do you think?

greetz,
Andy

Hi,
no i didn`t see this before. Do you know who drawing it? the wiring in this shematic doesn`t allow an clearing/Reset of the alarm. And the max input current of the ALM ports are 8mA...that means that a Resistor of 3kOhm is needed.

It was drawn by a centroid employee. Try to do a search on the forums for it.

[Andygraphy]

the drawing is not tested....

You should read that thread tho. It says you should be using a DB25 and a Relay Board.

[Andygraphy]

i did if you see the thread was originally from me. but it didn`t worked

[CNCMaryland]

Are you using a DB25? You probably need to provide more insight into how you are doing things.

No I`am not. i got the motors running via the normal connectors. thats not the problem. the question is at the alarm ports

while you can get these to run on the screw terminal, it is not ideal and opens you up to possible issues.
use the DB25 as the Centroid supplied schematic shows. If you choose to go a different route then its up to you to figure out.
