Section 14
Aligning Plates
The Automatic Plate Alignment (APA) feature detects the edges of a rectangular plate and calculates the degree of skew
to align a part on the plate. Two types of APA sequences are available:
 Five-point alignment is the default type of APA and detects plate alignment, skew, and size.
 Three-point alignment detects plate alignment and skew.
Notes about APA
 The APA sensors must be assigned in I/O setups. The logic states must be set so that the input is active when the
sensor is over the plate.
 The sensor moves fast to the outward edge of the plate until the sensor detects the edge and switches to OFF. For
accuracy, motion reverses until the sensor is activated again and switches to ON. See Sensing Sequence.
 If User Defined is selected as the Manual Offset value on the Manual Options screen, an X/Y tool offset value from
the Setup screen is required to compensate for the distance between the master torch and the APA sensor.
 Scrap clearance, if required, is entered on the Align screen. In addition, Corner to Align With on the Align screen sets
the start corner location of the program.
 If your machine requires homing, this function should be performed before APA.
 Some sensors may detect the table slats as an extension of the plate. If this is a problem in your application,
configure 2 sensors. The first sensor to detect the edge of the plate (switch to OFF) is used for all plate detection at
that location.
 An appropriate X/Y offset for the two sensors is recommended to minimize the possibility that both sensors could
detect the slats as an extension of the plate. The distance between the first and second sensor is programmed in tool
offset #11 on the Setup screen.
 Sensing radius should be programmed according to the radius of the sensor. If dual sensors are used, the radius
applies to both sensors.
 You can insert program codes into the part program to automatically configure 3-part APA for that part. For more
information, see
Program Code, later in this section.
