3-4-3 Connecting Origin and Positioning Completed Input Signals
The examples below show input connections when open collector sensor out-
put and the encoder’s Z-phase line driver output are used.
Use a sensor with no chattering, such as a photoelectric sensor, for the origin
input signal.
!Caution Connect a switch with a switching capacity of at least 5 mA to the 24-V origin
input signal terminal.
!Caution Do not connect the 5-VDC origin input signal input to any output circuit except
the line driver.
!Caution Use either the 24-V origin input signal or the 5-V origin input signal, but not
both. Also, be sure not to connect them to the wrong terminal. Using both sig-
nals or connecting them to the wrong terminal will result in damage to internal
circuitry.
