50/60 Hz setting

The frequency setting made in the factory can be adapted to the North American

using the 50/60 Hz DIP switch (refer to Fig. 3-15).

The switch determines the value of parameter P0100 corresponding to the
following diagram (refer to Fig. 3-16). Besides P0100 = 2, after the power supply
voltage has been switched-in, the 50/60 Hz DIP switch determines the 50/60 Hz
setting (value of parameter P0100).
