3-3-3. Direction switching
Mode switch 1-5 (direction switch) can be used to change the phase relationship of the A/B
phase output signal with respect to the travel direction of the encoder.
When the head PL101 is moved in the direction opposite to that in which the cable runs, the
A phase is the leading phase when the switch turns on. When the switch turns off, the B
phase becomes the leading phase.
