Hello Again,
Thanks for the quick reply. I used a Futureshop Dynex usb to rs232 converter and it worked like a charm on my first attempt. It seems to be able to detect the baud rate on its own has I did not need to set anything other than choosing the proper baud rate in vipertune. I found vipertune to be convivial and easy to figure out...nice and simple.
As a reminder, I am trying to use the original EL.GE: AZE-CC4Q: DC SERVODRIVE with the original motor and tach. The encoders are linear Heidenhain mounted on the xyz planes. Here are a few of the problems I have encountered.
1- Although my linear scale is powered, turning it by hand does not change the encoder count in scope. Making me think that my enconder sin to TTL does not work.
2- As soon as I release the emerg from Mach3, the motor runs away. I have switch encoder A and B as suggested in the manual without effect. It's almost like noise out of the step to linear (more or less 24mV) or the breakout board maybe. If I turn on the scope feature, the encoder count goes up, the error count goes up to and the steps stay at 0.
3- Pressing the jog button in any direction will not affect the "run away" state of the motor...does not speed or slow down, it will however make the scope steps go up
4- The scope encoder counter is moving but I do not see changes in the scope graphic window.
5- Playing with the Proportional gain seems to simply multiply the noise and the speed of run away. KD, KI and loop time, seems to have very little effect on my drive.
Any ideas? I must be missing something...
Thanks
Eric
