 Here you can choose the torque limit profile that the
Soft-Starter SSW-06 shall supply to the motor during the start.
 Three different types of torque profiles are available that permit
improving the speed performance during the start process.
Tn(%)
 Here you can program the end torque limit or constant for the stop,
10 to 100
[ 20 ]
according to the torque type selected at P125.
 For more details about programming and application, refer to Torque
Control at P202.

NOTE!
Choose the type of torque control, easier to program and set,
according to the knowledge about the characteristics of the load.
P126
1 (Constant) P126 limits the maximum torque during the stop process
2 (Linear) P126 limits the end torque during the stop process
3 (Quadratic) P126 limits the end torque during the stop process
