Repair-bench safety evidence

Bench Fake-Load / Reduced-Energy Output Evidence Record

Documents why controlled load and reduced stored energy are used to protect scarce modules while verifying a repaired output stage.

Repair Bench Fake-Load and Reduced DC-Link Evidence Path

A public safety-oriented map of why experienced repair benches reduce stored energy and use controlled load evidence before proving an output stage after destructive module repair.

Turn this record into a qualified service request

A repair decision is much more reliable when the request includes the exact identity of the drive, the first fault evidence and the machine condition when the symptom appeared.

  • Complete drive type code / MLFB or nameplate model
  • Fault code, fault value and first event before reset
  • When the event appears: power-up, enable, ramp, run, decel or stop
  • Motor/cable connected or isolated during the symptom
  • Visible board, option-card, module and connector identifiers
  • Previous repair history, replacement parts and repeat-failure pattern
