Speed monitor (internal overspeed protection)
The Speed monitor function is an internal overspeed protection function. It
supervises the speed of the motor and trips the drive at motor overspeed. The
function defines the motor overspeed level in percentage of the minimum (Par.
) or maximum speed (Par.
), as well as maximum external speed (Par.
) and minimum external speed (Par.
). The default value is 110%.
If the motor speed exceeds the limit defined with a parameter, the drive trips to a
fault, the converter is switched off and the mechanical brake is controlled on.
