Symptom / Description

FAULT

The motor struggles to reach its set speed or its rotation speed fluctuates abnormally.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

The drive detects excessive slip (difference between commanded speed and actual speed), often caused by a significant overload or mechanical problem.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

1. Pre-Intervention Electrical Safety Protocols
  • !High-Voltage Safety Protocol & DC Bus: Wait at least 5 minutes after power cutoff to allow inverter DC bus capacitors (380V DC) to bleed down.
  • !Verify 0V DC across inverter filter capacitors before unplugging motor harness connectors.
  • !Keep hands clear of drive belt and pulleys during any manual rotation tng.
3. Preliminary Mechanical & Visual Checks
  • Slip off drive belt and spin drum/motor shaft by hand to check for roaring or seized ball bearings.
  • For universal motors: verify carbon brushes have at least 10mm remaining length and smooth contact faces.
  • Inspect motor suspension rubber mounts and drive belt tension/groove profile.
