Ok. Just ordered an IP-M

guys quick question, if I decide to get the CSMIO-IP-M with leadshine EM806, do I have to use resistors to limit the current of pul/dir signals? it is mentioned in the driver document but is it really necessary since output is so low from the CSMIO?

I've got this controller with am882 drivers. If the am882 step and direct ports are featured with 5v then the datasheet says no resistors are needed, and on the csmio-ip-m it's says somewhere in the manual that the step and direct outputs are at 5v so I've not installed and resistors.

hmm ok so it outputs 5V for step/dir signals but 24v for other I/O ? I guess that works out but I quickly glanced at the manual it does say 5v but not exactly being direct about it. I heard it mentioned in the forums that the CSMIO has advantage of everything running at 24v so I assumed the step/dir was at 24v as well

thanks for the info!

I'm not sure that only being 5V matters too much in this case. Connections will be short inside the control box, and if you use twisted pair and differential connections there is a pretty high degree of noise immunity anyway. You will be using differential connections?

Didn't see the other posts answering the question but just to back up what neale says about being 5v. The Cslabs are by far the best controllers I've used when it comes to noise immunity and by some way. Not many controllers can handle working along side high frequency devices like TIG welders but these do without any sign of trouble.
Wiring with differential connections is essential to give you best protection so makes sure you do.

will do, once I succumb to purchasing it haha , thanks all.

No don't need resistors the Motor output logic are 5v differential which is common Input logic on most drives. Being differential makes them very noise immune. I/O logic is 24v which is very important when it comes to noise.
