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.

N.O.: Activated when detected
H2-01, H2-02, H2-03, H2-04 = 18
H2-01, H2-02, H2-03, H2-04 = 17
N.C.: Deactivated when detected
H2-01, H2-02, H2-03, H2-04 = 19

The drive sets the Overtorque/Undertorque detection level in these conditions:
V/f, CL-V/f, OLV/PM: Current level (drive rated current = 100%)
OLV, CLV, AOLV, AOLV/PM, CLV/PM, EZOLV: Motor torque (Motor rated torque = 100%)
L6-08 ≠ 0 [Mechanical Fatigue Detect Select ≠ Disabled]: Current level (drive rated output current = 100%)
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 you set L6-02 and H3-xx = 7, the analog input is most important and the drive disables L6-02.
You cannot use Overtorque/Undertorque Detection 2 to set the detection level for the analog input terminals.
