CN1 Pin Arrangement
Note: Do not connect anything to unused pins (those marked with *).
The input functions for general-purpose inputs 1 to 8 (or IN1 to IN8) and the output functions for general-purpose
outputs (OUTM1 and OUTM2) are determined by the objects 3400 to 3407 hex (Input Signal Selection 1 to 8)
and objects 3410 and 3411 hex (Output Signal Selection 1 and 2). The functions that are allocated by default
are given in parentheses. Refer to 7-1 Sequence I/O Signals on page 7-1 for the allocation.
To use an absolute encoder, connect a battery to pin 14 and 15, which is the backup battery input, or connect
the battery to the holder of the absolute encoder cable. (Never connect to both.)
