Preassigned Q parameters
The Q parameters Q100 to Q199 are assigned values by the TNC.
The following types of information are assigned to Q parameters:
Values from the PLC
Tool and spindle data
Data on operating status
Results of measurements from touch probe cycles etc.
The TNC saves the values for the preassigned Q parameters Q108,
Q114 and Q115 to Q117 in the unit of measure used by the active
program.
Preassigned Q parameters (QS parameters) between
Q100
and
Q199
(
QS100
and
QS199
) must not be
used in NC programs as calculation parameters.
Otherwise you might receive undesired results.
Values from the PLC: Q100 to Q107
The TNC uses the parameters Q100 to Q107 to transfer values
from the PLC to an NC program.
Active tool radius: Q108
The active value of the tool radius is assigned to Q108. Q108 is
calculated from:
Tool radius R (tool table or
G99
block)
Delta value DR from the tool table
Delta value DR from the
T
block
The TNC remembers the current tool radius even if
the power is interrupted.
Tool axis: Q109
The value of Q109 depends on the current tool axis:
Tool axis
Parameter value
No tool axis defined
Q109 = –1
X axis
Q109 = 0
Y axis
Q109 = 1
Z axis
Q109 = 2
U axis
Q109 = 6
V axis
Q109 = 7
W axis
Q109 = 8
