Chapter 6: Fine-Tuning
With a dark background, you will want to adjust the setting for ThresholdBlack and Threshold-
White.
By triggering the motion sequence 1000 – 1003, you can test how the parts will dispense inside
the three zones when different motion sequences are triggered.
From the fd.main() program, in the four cases related to triggering motion sequence 1000 –
1003, you can adjust the fd.front.thres, fd.flip.thres, and fd.disp.thres to achieve the most effi-
cient settings.
CASE TRUE OF
VALUE front.den > fd.front.thres:
VALUE flip.den > fd.flip.thres:
VALUE dispense.den < fd.disp.thres:
VALUE flip.den < fd.flip.thres:
END
The default value of the fd.front.thres, fd.flip.thres, fd.disp.thres is set to 10. You can customize
those values by going to the Workspace Explorer window. Select:
e-Series Controller 60 > V+ User Variables > Reals > fd.disp.thres
(or fd.front.thres or fd.flip.thres) in the V+ user variable module by typing in the number you
want to use.
By experimenting with the motion sequence parameters, and how they affect the feeder oper-
ation, you can optimize the feeder performance so that you always have the number of parts
you want inside the dispense zone, flip zone and front zone.
Other ACE Sight Vision Tools
Other vision tools can be added, such as the Gripper Clearance tool shown below:
; Move the product backward from the front zone
CALL fd.execute(fd.ms.frontmove)
; Flip the product in the pick zone
CALL fd.execute(fd.ms.pickflip)
; Dispense more product into the feeder
CALL fd.execute(fd.ms.dispense)
; Move the product from dispense zone to the pick zone
CALL fd.execute(fd.ms.pickmove)
