The Berges ACM‑D2 11 kW is a three‑phase industrial inverter drive used to control servo motors or other variable‑speed loads. Common failure points on this class of units include power supply board component burn‑outs (especially the IGBT module and gate driver ICs), overheating of the motor controller due to inadequate cooling, and degradation of the input filter capacitors leading to ripple and noise faults. First‑check diagnostics should begin with verifying that the 380–460 VAC input is within spec and that the main power supply board shows no obvious signs of damage or burnt components; then inspect the IGBT module for discoloration or cracking, and finally review any error codes displayed on the drive’s panel or communicated via its communication interface.[oss-gpt-20b]
