Set the torque limit function to limit the torque applied to the load, or limit the
regenerating value.
. When the torque limit function is used, the priority of the torque control is higher than
the motor speed control and the compensation. Therefore, the acceleration /
deceleration time may be extended, and the motor speed may be reduced.
. There are two ways applied for torque limit:
Set the parameters used of the torque limit (21-05 to 21-08).
Set the torque limit by using the multi-function analog input (AI2).
(1) Set the parameters used of the torque limit (21-05 to 21-08).
. There are four torque limits can be set separately:
(I) Positive torque limit of forward side (21-05 positive torque limit)
(II) Positive torque limit of reversal side (21-06 negative torque limit)
(III) Negative torque limit of reversal side (21-07 forward regenerating torque limit)
(IV) Negative torque limit of forward side (21-08 reversal regenerating torque limit)
Refer to Figure 4.3.127.
Figure 4.3.127 Torque limit setting
(2) Set the torque limit by using multi-function analog input (04-05)
. Multi-function analog input (AI2) can be used to limit the torque. Use any one of or
both of setting parameters 04-07(AI2 function selection) for the input requirement.
Refer to the table 4.3.18 below for setting the rated torque limit function.
