A-, B- and Z-phase signals are input from the encoder.
(For details of pulse signal, refer to page 18.)
Input power for the encoder power supply.
Connect the external power supply (5V, 12V, 15V, 24V) and the power
cable from encoder. When the encoder output is the differential line
driver type, only 5V can be input. Make sure the voltage of the external
power supply is the same as the encoder output voltage.
