z Complementary output
Complementary output is a method to output via two tran-
sistors.
The wiring is connected to the 0-V side when output is ON and to
the power-supply side when output is OFF.
This design does not allow the wiring to be left open (at a
high impedance) as with the case of open-collector output
encoders.
Therefore, this provides a stable output from the encoder.
z Recommended product
E6C3-CWZ5GH (Manufacturer: OMRON)
Additional Information
For pulse train input, use the pulse train input RP terminal and the multi-function Input S7 terminal of
the control circuit terminals.
Be sure to use a complementary-output type encoder.
Connect the phase-A/B 90 ° phase difference pulse train as shown in the diagram below.
• Connect the phase-A signal to the pulse train input terminal RP.
• Connect the phase-B signal to the multi-function Input S7 terminal and set the Multi-function Input S7
Selection (C007) to 85 (EB: Rotation direction detection).
• If the encoder signal is connected, you need to complete wiring for other multi-input terminals S1 to
S6 in the source logic (PNP).
• The control circuit terminal P24 of the inverter is for a 24-V, 100-mA max. power supply. It can be
used for the encoder power supply if the consumption current for the input terminals in use and the
encoder power supply is allowable. However, this terminal must be isolated from any 24-V system
power supply for other than the encoder and inverter.
Crosstalk : A phenomenon by which signals are erroneously transmitted between different
phases. Specifically, the rising/falling edge signal from phase A is superimposed on
the signal from phase B and the rising/falling edge signal from phase B is superim-
posed on the signal from phase A, respectively.
