Ex-e protection

What does F110 mean?

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

Click steps to track your progress.

1. 1

   Review the application's project planning to ensure compliance with Ex-e motor operating limits below 5 Hz.

2. 2

   Modify the control logic or process to shorten the duration of motor operation below 5 Hz.
