For example, the application requires report of Err11 when the motor runs at 150% of rated motor current for two minutes.
According to Figure 7-47, 150% (I) is in the range of 145% (I1) and 155% (I2). 145% corresponds to the overload protection time 6
minutes (T1) and 145% corresponds to the overload protection time 4 minutes (T2). You can calculate the overload protection time
T corresponding to 150% from the following formula:
