<1> The following is valid for activation:
The function module "Extended messages/monitoring” must be activated (r0108.17 = 1).
The maximum duration must be set to a value exceeding zero (p3242 > 0).
A separately-excited synchronous motor (SESM) is used.
<2> p3242 (setting example):
It should be possible to use 150 % of the input variable for a duration of 3 s at a permissible continuous rating
of p3241 = 110 %.
p3242 = ((150 x 150 - 110 x 110) / ((100 + 110) x (100 + 110) - 110 + 110) x 3 s = 0.975 s
