4. AUXILIARY AND APPLIED FUNCTIONS
4.1 Limit Switch Output Function
This function is used to output the ON/OFF signal corresponding to the data range of
the watch data set per output device.
Motion control data or optional word data can be used as watch data. (Refer to Section
"4.1.2 Limit output setting data" for details.) A maximum output device for 32 points can
be set regardless of the number of axes.
4.1.1 Operations
(1) ON output to an output device is made while the watch data value is in the ON
output region set with (ON Value) and (OFF Value) in this function.
(a) (ON Value), (OFF Value) and watch data value are handled as signed data.
ON output region where an ON output is made to the output device is
governed by the magnitude relationship between (ON Value) and (OFF
Value) as indicated below.
Relationship between (ON Value) and
(OFF Value)
ON output region
(ON Value) < (OFF Value) (ON Value) <= (watch data value) < (OFF Value)
(ON Value) > (OFF Value)
(ON Value) <= (watch data value)
(Watch data value) < (OFF Value)
(ON Value) = (OFF Value) Output OFF in whole region
