V20 F11 (Motor overtemperature) — cause?

Motor overloaded. May also occur with small motors (<=250 W, 4- or 2-pole) run below 15 Hz even when motor temperature is within limits.

V20 F11 — how to fix?

Reduce load/load step, set motor nominal overtemperatures (P0626-P0628) and warning level (P0604) correctly. If small-motor low-speed case and temperature is within limits, set P0335 = 1.
