Common failures on this model include power supply board degradation (overheating of MOSFETs or capacitors), controller firmware corruption, and phase sensor drift leading to motor stalling or erratic torque. Initial diagnostics should verify the 48 VDC input voltage and continuity across the drive’s main power rails; check I/O status LEDs for fault codes and inspect the PCB for burnt components or loose connections; finally review any stored error logs via the drive’s diagnostic interface.
