Torque Limit Function Settings
The torque limit function is for limiting the output torque of the motor.
• With the torque limit function, the following torque limit values are applied according to torque limit
switching 1 and 2, analog voltage/current input and operation state allocated to 1st Drive Control
Selection (F42)/2nd Drive Control Selection (A14), Torque Limit Operation Selection (H75) and mul-
tifunction input.

*1. To enable analog input, set “7: Analog torque limiter” to one of Input Terminal [AI1] Function Selection
(E61), Input Terminal [AI2] Function
Selection（AII） (E62) or Input Terminal [AI2] Function Selection
（AIV） (E63).
*2. Power running indicates the 1st and 3rd quadrants, and regeneration indicates the 2nd and 4th quad-
rants.
• Setting “184: TL (torque limit enabled)” to Input Terminal [DI1] Function Selection to Input T
erminal
[DI7] Function Selection (E01 to E05, E98, E99) enables the torque limit function only when the TL
is input.
