6.2 I/O Signal Allocations
Functions are allocated to the pins on the I/O signal connector (CN1) in advance. You can
change the allocations and the polarity for some of the connector pins. Function allocations
and polarity settings are made with parameters.
This section describes the I/O signal allocations.
6.2.1 Input Signal Allocations
Changing Input Signal Allocations
 Input Signals That Can Be Allocated to CN1-40 to CN1-46
The input signals that you can allocate to the pins on the I/O signal connector (CN1) and the
related parameters are given in the following table.
• If you change the polarity of the /S-ON (SERVO ON Input) signal from the default setting, you
will not be able to turn OFF the main circuit power supply to the Servomotor if signal lines break
or other problems occur. If you change the polarity of this signal, verify operation and make
sure that no safety problems will exist.
• If you allocate two or more signals to the same input circuit, a logical OR of the inputs will be
used and all of the allocated signals will operate accordingly. This may result in unexpected
operation.
