Hi Everyone.
I am asking this question on a behalf of a collegue of mine.
Before I go to the specific of the question, I just want to mention that he has try to contact NI twice and since he had no access to the subscription number, he was turned down twice. Since he his the one doing all the hardware ordering, well let just say he vowed never to order a thing from NI again. I do believe that NI new support policy is a big mistake.
Now about the question.
We have a PCI-7344 card along with a MID 7654. 3 axes connected to the MID 7654 are done using a typical differential line driver encoder (and they all work fine). Now we just decide to add a fourth axe and we bought a DC Micromotor Series 2342-048 CR with a HEDS 5540 3 channel encoder from MicroMo Electronics. We are trying to connect this motor using typical single ended encoder with a 2.2 kOhm pullup resitor and we are having problems. At best the motor spin but we can stop it only by killing it, and we have no control over the velocity.
I seem to remember someone mentioning using motors from MicroMo Electronics. Can anyone gave us some advice or directions to try to figure out if that motor can work with our setup ?
Regards
