Fix T6 Servo Modbus Errors

I’m integrating a T6 AC Servo motor into a Python workflow over Modbus so that its motion follows real-time hand positions detected with MediaPipe. The Modbus link is live, but whenever I issue motion commands the drive flashes Error 100 most consistently (occasionally 180 or 102). Until that fault is eliminated the rest of the pipeline is stuck.

I need someone who already knows this drive family and the quirks of Modbus register maps. Your task is to pinpoint why the servo refuses the command—whether it’s a parameter, register offset, timing, checksum, or anything else—and then deliver a clean sample script that drives a simple move without triggering faults. I should be able to feed XYZ targets coming from MediaPipe and watch the motor track smoothly.

Deliverables
• Diagnosis of the root cause behind Error 100 (plus why 180 / 102 sometimes appear)
• Corrected Modbus command sequence or register settings, shared as a clear Python example (pymodbus, minimal dependencies)
• Brief notes so I can expand the script to stream MediaPipe coordinates

If you have successfully tamed this model or a close cousin, I’d love to see it in action.
