Description of I/O Signals

2
Point detection, area 1: Sequence output signal (Reference value 17)
Point detection, area 2: Sequence output signal (Reference value 18)
The current position of the servomotor is detected and output in these signals.
This function is enabled after homing or position preset.

Function
Three types of the output format can be selected through settings of PA2_31 (point detection, area
detection).
The signal can be output at two points with point detection, area 1 and 2.
(1) PA2_31 (point detection, area detection) = 0: point detection
The signal is turned on near the position specified with PA2_32 (point detection, area detection 1)
or PA2_33 (point detection, area detection 2).
(2) PA2_31 (point detection, area detection) = 1: ON for positive side
The signal is turned on at a position beyond the setting of PA2_32 (point detection, area detection
1) or PA2_33 (point detection, area detection 2).
The signal is turned off below the setting.
(3) PA2_31 (point detection, area detection) = 2: ON for negative side
The signal is turned on below the setting of PA2_32 (point detection, area detection 1) or PA2_33
(point detection, area detection 2).
The signal is turned off beyond the setting.
 Parameter setting
To assign point detection and area 1 to a sequence output terminal, specify the corresponding
value ("17") to the output terminal function setting parameter. Specify ("18") for point detection and
area 2.
