CJ1M CPU Unit Built-in I/O Specifications Appendix B
Note In order for the counter inputs to satisfy the specifications shown in the table
above, it will be necessary to check the factors that can affect the pulses, such
as the type of output driver in the encoder, encoder cable length, and count
pulse frequency. In particular, the rise time and fall time may be too long and
the input waveform may not be within specifications when a long encoder
cable is used to connect an encoder that has 24-V open collector outputs.
When a long cable is connected, either shorten the encoder cable or use an
encoder with line driver outputs.
Built-in Outputs (CJ1M-CPU2@)
Transistor Outputs (Sinking)
General-purpose Outputs
Pulse Outputs (OUT0 to OUT3)
Note 1. The load at the above values is taken as the resistance load, and the connecting cable impedance is
not taken into account.
2. The pulse width during actual operation may be smaller than the above values as a result of pulse
pattern distortion due to connecting cable impedance.
