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.
For SV22 advanced synchronous control, specifications are different from those of
the conventional limit switch output function and a maximum output device of 64
points can be set. (Refer to Section 4.1.3 and Section 4.1.4 for details.)

4.1.1 Operations

(1) ON output to an output device is made while the watch data value is in the ON
(ON Value) < (OFF Value)
(ON Value) > (OFF Value)
(ON Value) = (OFF Value)
POINT
output region set with (ON Value) and (OFF Value) in the limit switch output
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.
