Make the connections as shown below when using a sensor's open-collector
output and an encoder's phase-Z line driver output.
Use a sensor without chattering, such as a Photoelectric Sensor, for the Ori-
gin Input Signal.
Note 1. Connect a switch or sensor with a switching capacity of 6 mA to the Origin
Input Signal (24 V DC) terminal.
2. Connect only a line driver circuit to the Origin Input Signal (line driver) in-
puts. Do not connect any kind of output circuit.
3. Use either the Origin Input Signal (24 V DC) or Origin Input Signal (line
driver).
Verify that the Origin Input Signal is connected to the correct terminals.
The CPU Unit's internal components may be damaged if both inputs are
used simultaneously or the input is connected to the wrong terminal.
