5.9 Programmable motion end criterion (SW 5.1 and higher)
Programming
FINEA[<axis>]
COARSEA[<axis>]
IPOENDA[<axis>]
Explanation of the commands
FINEA
Motion end when "Exact stop FINE" reached
COARSEA
Motion end when "Exact stop COARSE" reached
IPOENDA
Motion end when "Interpolator-Stop" reached
Axis
Channel axis name (X, Y, ....)
Function
Similar to the block change criterion for continuous-
path interpolation (G601, G602 and G603), the end
of motion criiterion can be programmed in a part
program for single axis interpolation or in
synchronized action for the command-/PLC-axes.
Depending on the end of motion criterion set, part
program blocks or technology cycle blocks with
single axis motion
take different times to comlete.
The same applies for PLC-positioning statements
via FC15/ 16/ 18.
System variable $AA_MOTENDA
The set end of motion criterion can be polled using
the system variables
$AA_MOTENDA[<axis>]
.
•
$AA_MOTENDA[<axis>] = 1
Motion end with "Exact stop fine"
•
$AA_MOTENDA[<axis>] = 2
Motion end with "Exact stop coarse"
•
$AA_MOTENDA[<axis>] = 3
End of motion with "IPO-Stop".
Additional notes
The last programmed value is retained after RESET.
