Active coordinate system
211 – - 1 = input system (default)
2 = REF system
3 = tool change system
Special transformations in turning mode
1 - Angle for the precession of the input system
in the XY plane in turning mode To reset the
transformation the value 0 must be entered
for the angle. This transformation is used in
connection with Cycle 800 (parameter Q497). 215
3 1-3 Reading out of the spatial angle written with
NR2
Index: 1 - 3 (redA, redB, redC)
Current datum shift
2 Axis Current datum shift in [mm]
Index: 1 - 9 (X, Y, Z, A, B, C, U, V, W)
3 Axis Read the difference between reference point
and preset.
Index: 1 - 9 (X, Y, Z, A, B, C, U, V, W)
220
4 Axis Read values for OEM offset.
Index: 1 - 9 ( X_OFFS, Y_OFFS, Z_OFFS,... )
Traverse range
2 Axis Negative software limit switches
Index: 1 - 9 (X, Y, Z, A, B, C, U, V, W)
3 Axis Positive software limit switches
Index: 1 - 9 (X, Y, Z, A, B, C, U, V, W)
5 - Software limit switch on or off:
0 = on, 1 = off
For modulo axes, either both the upper and
lower limits or no limit at all must be set.
12 Axis Persistently overwrite the value for the
negative software limit switch in CfgPosition-
Limits.
Index: 1 - 9 (X, Y, Z, A, B, C, U, V, W)
230
13 Axis Persistently overwrite the value for the
positive software limit switch in CfgPosition-
Limits.
Index: 1 - 9 (X, Y, Z, A, B, C, U, V, W)
Read the nominal position in the REF system
240 1 Axis Current nominal position in the REF system
Read the nominal position in the REF system, including offsets (handwheel, etc.)
241 1 Axis Current nominal position in the REF system
Read the current position in the active coordinate system
270 1 Axis Current nominal position in the input system
Read the current position in the active coordinate system, including offsets (handwheel, etc.)
