Using negative logic for programmable I/O terminals
The negative logic signaling system can be used for the digital input and output terminals by setting
the function codes specifying the properties for those terminals. Negative logic refers to inverted
ON/OFF (logical value 1 (true)/0 (false)) state of input or output signal. An ON-active signal (the
function takes effect if the terminal is short-circuited.) in the normal logic system is functionally
equivalent to OFF-active signal (the function takes effect if the terminal is opened.) in the negative
logic system.
To set the negative logic system for an I/O signal terminal, display data of 1000s (by adding 1000 to
the data for the normal logic) in the corresponding function code and then press the
key.
For example, if a coast-to-stop command (BX: data = 7) is assigned to any one of digital input
terminals [X1] to [X3] by setting any of function codes E01 through E03, then turning (BX) on will
make the motor coast to a stop. Similarly, if the coast-to-stop command (BX: data = 1007) is as-
signed, turning (BX) off will make the motor coast to a stop.

Restriction on data displayed on the LED monitor
Only four digits can be displayed on the 4-digit LED monitor. If you enter more than 4 digits of data
valid for a function code, any digits after the 4th digit of the set data will not be displayed, however
they will be processed correctly.
