3.5.1  50/60 Hz setting 
The frequency setting made in the factory can be adapted to the North American 
market, without requiring any parameterization using an operator panel or PC tool 
using the DIP50/60 switch (refer to Fig. 3-21) under the I/O board (refer to the 
Appendix C when removing the I/O board).

The switch determines the value of parameter P0100 corresponding to the 
following diagram (refer to Fig. 3-22). Besides P0100 = 2, after the power supply 
voltage has been switched-in, the DIP50/60 switch determines the 50/60 Hz setting 
(value of parameter P0100).
