The existing drives used mecholink control that is to hard to talk to and I had the spare drives sitting in shed for years. I paid 10 bucks each lol so that's good at least. The motors are existing. I have had to set up lots of stuff on the drives and the only thing that I had to tune them was the auto tuning function. Which was not that good. So far torque mode has been pretty good. But I might try two nested loops yet. Y axis is really good like max following error 0.04 at 16m/min X axis motor runs out of torque. And just can't keep up. I can set drive to push 300 percent rated torque through motor briefly. What do you guys think of that, is it OK? Factory default is set to 300 percent. I changed it to 100 percent
Peak torque of 3X to 5X continuous mode torque is pretty standard for servo motor torque limits. By setting this to 100% you are severely handicapping your motors.
