Overtorque/Undertorque Selection (OTQ)
This function outputs a signal upon detection of the estimate motor output torque exceeding a
given level. This function is enabled only when Sensorless Vector Control is selected for
control method (A044/A244 = 03). Take note that under all other settings, the output becomes
indeterminable.
This function is enabled when the Overtorque/Undertorque (07: OTQ) is selected in Multi-
function Output Terminal Selection.
