Indramat DKC F281: Mains Fault

What F281 means

The mains supply dropped out for several cycles while the drive was running.

Symptoms

Fault under load or on supply disturbances.

Is it repairable?

Usually supply related; repairable when the drive's input section is faulty.

Common causes

  • Missing phase
  • Loose supply connection
  • Supply dips

Safe checks

  1. 1Measure all three supply phases
  2. 2Check connections and fuses

Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.

Reviewed by AutomIQ repair technicians. Code and name from the ECODRIVE DKC and ECODRIVE03 diagnostic descriptions.
