YASKAWA AC Drive GA700 High Performance Type Technical Manual
You can individually set the two overtorque/undertorque detection functions with the drive. Use the information in Table 1 to set the parameters.

In V/f Control, the drive uses the current level (100% of the drive rated output current) to detect overtorque/undertorque. In vector control, the drive uses the motor torque (100% of the motor rated torque)to detect overtorque/undertorque. When you enable the mechanical weakening detection function, the overtorque/undertorque detection level for all control modes is the current level (100% of the drive rated output current).
You can also use an analog input terminal to supply the torque detection level. To enable this function, set H3-xx = 7 [MFAI Function Selection = Overtorque/Undertorque DetectLvl]. If both L6-02 and H3-xx = 7 are set, the analog input has priority and the setting of L6-02 is disabled.
You cannot use Overtorque/Undertorque Detection 2 to set the detection level for the analog input terminals.
