Additional Information
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.
For pulse train input, use the pulse train input EA terminal and the multi-function Input 7 terminal of the
control circuit terminals.
Be sure to use a complementary-output type encoder.

*1. Direction signal can be input in favor of the sink or source logic, independent of the output method of the en-
coder signal.
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 EA.
• Connect the phase-B signal to the multi-function Input 7 terminal and set the Multi-function Input 7
Selection (C007) to 85 (EB: Rotation direction detection).
• If the encoder signal is connected, you need to complete wiring for other multi-input terminals 1 to 6
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.
