T3: Tangential control - 840D sl only
11.3 Using tangential follow-up control
TANGDEL(C)
The existing definition in the example of TANG(A, X, Y) is canceled.
Example for plane change
Program code
N10 TANG(A, X, Y, 1)
N20 TANGON(A)
N30 X10 Y20
...
N80 TANGOF(A)
N90 TANGDEL(A)
...
N120 TANG(A, X, Z)
N130 TANGON(A)
...
N200 M30
Example for geometry axis switchover
If the definition of the follow-up axis assignment is not canceled, an attempt to execute a
geometry axis switchover is suppressed and an alarm is output.
Program code
N10 GEOAX(2,Y1)
N20 TANG(A, X, Y)
N30 TANGON(A, 90)
N40 G2 F8000 X0 Y0 I0 J50
N50 GEOAX(2, Y2)
Geometry axis switchover with TANGDEL
The following example shows how TANGDEL is used correctly in association with an axis
switchover.
Program code
N10 GEOAX(2,Y1)
N20 TANG(A,X, Y)
N30 TANGON(A, 90)
N40 G2 F8000 X0 Y0 I0 J50
N50 TANGOF(A)
N60 TANGDEL(A)

Comment
; Defined coupling from A to X and Y as
; Delete leading axes
; A can be coupled to new leading axes
Comment
; Alarm 14415, geometry axis to be deleted is still
; leading axis of follow-up axis assignment
Comment
; Geometry axis group is determined
; Channel axis Y1 is being assigned
; Follow-up group with Y1 is being activated
; Movement block for the leading axes
; Activation of follow-up control
; Deletion of the definition of follow-up
; axis assignment
