[3]=50 Hz
Use the 4 current points [A] from the motor nameplate. Calculate the values as a percentage of nominal motor current, I
and enter the values into the array. All operating points underneath the curve are allowed continuously. Above the line, however, these
points are only allowed for a limited time calculated as a function of the overload. When machine current is greater than 1.5 times the
rated current, shutdown is immediate.
All frequency/current limit points from the motor nameplate of motor datasheet must be programmed.
