Drive over temperature fault

What does F14 mean?

The heatsink temperature of the drive has exceeded its acceptable operating limits, triggering a fault. An overtemperature warning typically precedes the actual trip limit. Sustained high temperatures significantly reduce the lifespan of power semiconductors and other internal components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Measure and confirm that the ambient temperature around the drive is within specified operating limits.

2. 4

   Consider reducing the switching frequency parameter if ambient temperatures are high or the motor load is significant.
