4.2.100 Torque LAD stop function
The torque LAD stop function is effective when "03" (sensorless
vector control) is specified for the V/F characteristic curve
selection (A044/A244). This function temporarily stops the
frequency-based deceleration function (LAD) when the torque
limitation function operates.
