During torque limitation
(a) Analog input mode
It is a mode to set a torque limit value in all operation states by applied voltage/current by setting
the Ai1/Ai2/Ai3 terminal on the control terminal block in the torque limit selection [bA110].
In the case of setting torque bias, values corresponding to analog input are as follows.
• Input to Ai1/Ai2 Terminal
0 to 10 (V)/0 to 20 (mA) corresponding value
Torque command addition 0.0 to 500.0(%)
• Input to Ai3 Terminal
-10 to 10 (V) corresponding value
Torque command addition -500.0 to 500.0(%)
The setting of the ratio above can be changed by adjusting the analog input start end function.
See 8-10-5 Analog Input on page 8-163.
(e.g.) In the case of setting 0.0 to 50.0% to the torque command addition value for 0-10 (V)/0-20
(mA) input as [Ai1], set 10.0% for [Cb-04] to make it 50.0% against maximum 500.0%.
([Cb-03]=0.0,[Cb-04]=10.0,[Cb-05]=0.0,[Cb-06]=100.0)
(b) 4 Quadrant specific setting mode
It is a mode to set respective torque limits 1 to 4 ([bA112] to [bA115]) in the four quadrants of normal
powered, normal regenerative, reverse powered, and reverse regenerative.
It will be enabled when torque limit selection [bA110] = 07 (parameter setting) and torque limit mode
selection [bA111] = 00 (by each quadrant).
The relationship of four quadrants and torque limits is shown in the figure below.
