LSIS G100 - Torque Detection Protection Action

6.3.11 Torque Detection Protection Action
This feature outputs torque status to the multi-function relay if a motor overload or
sudden underload occurs. This feature is activated when the multi-function relay
(OU31, 33) is set to 43, 44.

The over and under torque detection action operates as shown in the figure by having
a hysteresis level of 10% compared to the motor's rated current.
