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).
