FUNCTION CODES
Chap 5
Under vector control with speed sensor (F42=6)
If the inverter’s output torque exceeds the specified levels of the torque limiters (F40, F41, E16, E17, and E61 to
E63), 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.
To use the torque limiters, it is necessary to configure the function codes listed in the Table 5.3-6.

■ Torque limiter (Control target) (H74)
Under vector control, the inverter can limit motor-generating torque or output power, as well as a torque current
(default).
