Introduction
The following example demonstrates how to setup a cartesian group. It will configure basic setup of an XYZ orthogonal system. The setup will be done in SETUP.PRG task.
Configuration
First of all, a cartesian group must be defined in CONFIG.PRG file:
common shared gXYZ as group Axnm = a1 Axnm = a2 Axnm = a3 model=1 of xyz
Axis Definition
Next, in the SETUP.PRG task, define subroutine for setting up a linear axis :
 | NOTE |
| It is assumed there is a global integer array pos_units[] defined in the system. It holds the position resolution of each axes; e.g., the number of counts in one full revolution of the motor. |
| NOTE |
| In this example it is assumed there is no gear between the linear screw and the motor, and the pitch of the screw is 5 mm per revolution |
sub SetAxis(ax as generic axis, byval vvv as double)
with ax
attach
en = 0
sleep 10
' simulated = 0
pfac = pos_units[elementid]/5 'For 5mm pitch
vfac = pfac/1000 ' mm /sec
afac = vfac/1000 ' mm /sec^2
jfac = afac/1000 ' mm / sec^3
vmax = vvv
amax = 1500
dmax = 1500
jmax = omega*amax ' Fast reacting
vcruise = vmax
acc = amax
dec = dmax
jerk = jmax
prftype = profile
smooth = -1
vospd = 2*vmax
velocitysafetylimit = 100*vmax
positionerrorsettle = 5
pemax = 1
pmaxen = 1
pminen = 1
disp = 0
abs = 1
positionrolloverenable = 0
' simulated = 1
Print "axis ";elementname;" set."
detach
end with
end sub
Group Setup
Now define a group setup routine for setting up the common group parameters.
| NOTE |
| It is assumed that the working range of the robot for every axis is between 0 mm and +300 mm |
sub SetGroup(gr as generic group)
dim i as long
with gr
attach
en = 0
sleep 10
vfac = 1/1000
afac = vfac/1000
jfac = afac/1000
positionerrorsettle = 2
pemax = 1
abs = 1
a1.axistype = 0
a2.axistype = 0
a3.axistype = 0
configgroup
vmax = 1000 ' mm/sec
amax = 1500 ' 1500 mm/sec^2
dmax = 1500 ' 1500 mm/sec^2
jmax = omega*amax
vcruise = vmax
acc = amax
dec = dmax
jerk = jmax
vmtran = vmax
amtran = amax
jmtran = jmax
vtran = vmtran
atran = amtran
dtran = amtran
jtran = jmtran
vmrot = vmax
amrot = amax
jmrot = jmax
vrot = vmrot
arot = amrot
drot = amrot
jrot = jmrot
xmax = 300
xmin = 0
ymax = 300
ymin = 0
zmax = 300
zmin = 0
rmin = 0
rmax = 4000
smooth = -1
prftype = profile
j1.pmin = 0
a1.pmin = 0
j2.pmin = 0
a2.pmin = 0
j3.pmin = 0
a3.pmin = 0
j1.pmax = 300
a1.pmax = 300
j2.pmax = 300
a2.pmax = 300
j3.pmax = 300
a3.pmax = 300
Print "group ";elementname;" set."
detach
end with
end sub
Complete Task
Lastly, the main program block of the SETUP.PRG:
dim shared profile as long = -1' 2 - Acceleration Trapeze Profile, -1-Sine Acceleration
dim shared omega as double = 15
program
call Setaxis(a1,1000) ' X max speed 1000mm/sec
call Setaxis(a2,1000) ' Y max speed 1000mm/sec
call Setaxis(a3,1000) ' Z max speed 1000mm/sec
call SetGroup(GXYZ)
end program
