Over-temperature

What does F-11 mean?

The inverter has detected a thermal overload, indicating its internal temperature has exceeded safe operating limits. This is typically due to excessive load, insufficient cooling, or potentially an improperly installed braking resistor. Prolonged operation at high temperatures can severely reduce the lifespan of inverter components.

Complete Troubleshooting Guide

1. 1

   Reduce the load on the drive to decrease the thermal stress on the inverter.

2. 2

   Ensure the inverter's cooling system (fans, heatsinks, ventilation) is clean and functioning correctly.

3. 3

   If a braking resistor is integrated into the heatsink and contributes significantly to heat, consider installing it externally.
