Mains failure

What does 36 mean?

The frequency converter has detected a loss of incoming supply voltage, and the 'Mains Failure' parameter (14-10) is configured to generate an alarm. This indicates a power supply interruption to the drive, which will cause the motor to stop. Until mains power is restored, the drive cannot operate.

Complete Troubleshooting Guide

1. 1

   Check the main fuses supplying power to the frequency converter for blown fuses.

2. 2

   Verify the incoming three-phase mains supply voltage is present and stable at the drive's input terminals.

3. 3

   Inspect all power wiring connections from the mains supply to the frequency converter for any loose or damaged terminals.
