I'm having an issue with the Beckhoff AX8000 drives. The drive is powering an asynchronous induction motor with no feedback to the drive. The drive never faults out for overcurrent or for torque when the motor is stuck and can't spin. I've thought about trying the parameter 0x32C8, but Beckhoff support has told me that doesn't work for asynchronous motors.
I was wondering if anyone here has experience with Beckhoff drives, specifically the AX8000, and if they could help answer some questions. I've talked to various different Beckhoff support, and they can't tell me how to setup the overcurrent protection either. I was told that if current exceeds the peak current parameter value, which is 2.85 amps, the drive should fault out after a certain time. I've had an amp clamp on each leg, and I saw 3.5 amps consistently outputted in a locked rotor scenario and the drive never faulted out.
