F40, F41 Torque Limiter 1 (Driving, Braking)
If the inverter's output torque exceeds the specified levels of the torque limiters (F40, F41,
E16 and E17), the inverter controls the output frequency and limits the output torque for
preventing a stall.
To use the torque limiters, it is necessary to configure the function codes listed in the table
below.
In braking, the inverter increases the output frequency to limit the output torque.
Depending on the conditions during operation, the output frequency could
dangerously increase. H76 (Frequency increment limit) is provided to limit the
increasing frequency component.
Torque limiters 1 and 2 (F40, F41, E16 and E17)

These function codes specify the operation level at which the torque limiters become
activated, as the percentage of the motor rated torque.


The torque limiter levels can be changed via the communications link. Function codes S10
and S11 exclusively reserved for the communications link respond to function codes F40 and
F41.
