Torque limit setting by using multi-function analog input AI2 (04-05)
Table 4.4.18 Torque limit analog input
04-05 (AI2) Function
11 Positive torque limit
12 Negative torque limit
13 Regenerative torque limit (for both forward and reversal directions).
14 Positive/negative torque limit (positive and negative detection torque limit )
Set the analog input terminal (AI2) signal level (04-00), gain (04-07) and bias (04-08)
The default setting for the analog input AI2 is 0 -10V representing 0
– 100% of the motor rated torque).
Figure 4.4.128 shows the relationship between the output torque and the torque limit.

Figure 4.4.128 Analog input torque limit (AI2)
When the analog input is set to positive torque limit (value = 11) the torque limit is active in the third and fourth
quadrant.in the reverse direction (regenerative torque in the second quadrant).
When the analog input is set to negative torque limit (value = 12) the torque limit is active in the third and fourth
quadrant.
When the analog input is set to regenerative torque limit (value = 13) the torque limit is active in the second and
fourth quadrant can be controlled.
When the analog input is set to positive/negative torque limit (value = 14) the torque limit is active in all four
quadrants.
