■ Single-phase pulse and forward/reverse rotation command wiring ([P004]=00, 03)
 When wiring for single-phase pulse or forward/reverse commands and single-phase pulse, refer
to the figure below.
Input a single-phase pulse to the [PLA] terminal, and a direction signal to the [PLB] terminal. The
[PLB] terminal is compatible with both sink logic and source logic by altering the position of the
short-circuit wire.
