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.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

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