Ex-e protection

Hva betyr F110 ?

The maximum allowed duration for operating the motor below 5 Hz in Ex-e protection mode has been exceeded. This fault initiates an emergency stop to comply with safety regulations for explosion-protected motors, which have thermal limitations at low speeds.

• Project planning or application design dictates extended motor operation below 5 Hz
• Operational conditions caused the motor to run at very low frequencies (below 5 Hz) for too long
