I've been attempting to replace a faulty drive with an AMC drive (DPRAINIR-015S400). It's a tad undersized for the application but I'll be upgrading to the 030S variant if I can get this working.
Some specs:
Machine: Hermle UWF851
Control: TNC 355
Servo: Siemens 1HU 3076 with tacho
Currently I have the drive enabling fine. Tuned per the AMC instructions. Feedback is setup as an analog input and is scaled via a voltage divider so as not to exceed the maximum +/-10V input range. Command is setup as velocity and is coming in another analog input.
Velocity input scale: 222.22 RPM/V Current Offset that works best (-0.017V)
Tach input scale: 202.51 RPM/V
I can move the drive around with the manual controls most of the time until the control throws an asterisk (*) letting me know it's waiting to reach position. I can usually do a quick rapid (in the same direction) and the asterisk will go away and normal operation resumes. Same thing occurs when running a simple program (waits to reach position with asterisk displayed sometimes a few moves in but always at the end of a move)
I thought I had it dialed but then tried to run a probe cycle. After staring the cycle, I touched the probe to simulate hitting an edge. The control threw up the asterisk and the control froze, necessitating an emergency stop and restart of the drives. Following that restart I got a "Processor Check Error 1". I've never seen that before.
Messed around with almost everything I can think of and I'm out of ideas. Missing something though. Any help is greatly appreciated.
