With an asynchronous motor, the estimation is typically less reliable at low speeds and more reliable at high speeds.

The effects of external accelerative forces are not taken into account in the values above. The values are valid in these conditions:
• The motor parameters have been set correctly, and the motor identification run has been completed successfully.
• The motor is not overloaded.
