Functions
When "00: Four-quadrant separate setting" is selected in Torque Limit Selection (b040),
Torque Limits 1 to 4 (b041 to b044) conform to the figure below.
When "01: Terminal switching" is selected in Torque Limit Selection (b040), Torque Limits 1 to
4 (b041 to b044), which are switched by Torque Limit Switchings 1, 2 allocated to multi-function
input terminals, are set as follows.
Example) Torque limit switching 1 (41: TRQ1) is allocated to multi-function input terminal S6,
and Torque limit switching 2 (42: TRQ2) is allocated to multi-function input terminal
S7/EB.
To use the torque limit function in a low-speed range, also use Overload Limit Selection (b021/
b221/b024).
Torque LADSTOP Function
This function temporarily stops the frequency deceleration function (LAD) when the torque limit
function is actuated. This function is enabled only when Sensorless Vector Control is selected
