Input Terminal Function [CA-01] to [CA-11]
Output Terminal [CC-01] to [CC-07]
(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
• Input to Ai3 Terminal
The setting of the ratio above can be changed by adjusting the analog input start end function.
See
(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.
