Description
Here it is possible to specify which position
data that should be displayed in P739-743.
Whenever this number is changed the
current values of P739-P743 are stored in
memory under the previously specified
index number. After that, the value of
P739-743 is updated with the data stored
in memory relevant to the newly specified
index number.
The meaning of this parameter depends
on the position type specified in P743.
If P743 = 0, the value of this parameter
refers to an absolute position (relative to
the fixed HOME position).
If P743 = 1 and the last position was obtai-
ned through jogging, the value of this para-
meter is a position relative to that position.
If the last position was reached as a result
of a positioning command, then the value
of this parameter specifies a position relati-
ve to the last target position (whether it
was reached or not).
If P743 = 2 the application will move in the
positive direction until a touch probe posi-
tion is defined. If a touch probe position is
already defined the application will move
directly to that position.
A touch probe position is defined as the po-
sition at which the "touch probe switch" input
(MK3A 1) goes high plus the value of P739.
A touch probe position is cleared by a high
signal on the "reset touch probe position"
input (MK3A 7) input.
The output "Touch probe position locked"
(VLT5000 Terminal 42) is high if a touch
probe position is defined.
If P743 = 3 the application will move in the
negative direction until a touch probe posi-
