5.3 Description of Function Codes 5.3.1 F codes (Fundamental functions)
Under speed sensorless vector control/vector control with sensor (induction motors, permanent magnet
synchronous motors) (F42 = 5, 6, 15, 16)
If the inverter’s output torque exceeds the specified levels of the torque limiters, the inverter controls the speed
regulator’s output (torque command) in speed control or a torque command in torque control in order to limit the
motor-generating torque.
