Changing Input Signal Allocations
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 default polarity settings for the /S-ON (Servo ON), P-OT (Forward Drive Pro-
hibit), or N-OT (Reverse Drive Prohibit) signal, the main circuit power supply will not be turned
OFF and the overtravel function will not operate if there are signal line disconnections or other
problems. If you must change the polarity of one of these signals, 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.
