Input phase loss

What does 3130 mean?

The drive has detected a loss of one or more phases in the incoming AC power supply. This condition reduces the drive's power capability and can lead to instability, protective tripping, or damage to internal components if operation continues unregulated.

Complete Troubleshooting Guide

1. 1

   Measure the voltage of each incoming AC supply phase at the drive's input terminals.

2. 2

   Inspect all upstream power components including fuses, circuit breakers, and contactors for proper operation and continuity.

3. 3

   Check the integrity of the power cabling from the source to the drive.

4. 4

   Verify that the supply network can reliably provide the required power to the drive without sags or interruptions.
