CN1 Pin Arrangement
Note.Do not connect anything to unused pins (*1).
For general-purpose inputs 1 to 10 (SI1 to 10) and general-purpose outputs (SO1, SO2 and SO4), use user
parameters Pn400 to Pn409 (Input Signal Selections 1 to 10) and Pn410 to Pn413 (Output Signal Selections 1 to
4) to set the function allocations.
The alarm output (/ALM) is fixed to general-purpose output 3. This is indicated with square brackets in the above
figure.
The function that is allocated by default is given in parentheses. “*2” indicates terminals that have different default
functions depending on the control mode.
Refer to "6-9 Sequence I/O Signal" (P.6-35) for details on allocations.
To use an absolute encoder, connect a battery to either Pin 42 which is the backup battery input, or 43 which is
the battery holder for absolute encoder cable. (Never connect to both.)
