4.13 Other G Functions
Deactivate zero offsets G920
”Deactivate” the workpiece zero point and the zero point shifts.
Traverse paths and position values are referenced to the distance tool
tip - machine zero point.
Deactivate zero offsets, tool lengths G921
”Deactivates” the workpiece zero point, zero point shifts and tool
dimensions. Traverse paths and position values are referenced to the
distance slide reference point – machine zero point.
Lag error limit G975
Switches to ”Lag error limit 2” (see machine parameter 1106, ..).
G975 is a modal function. At the end of a program the CNC PILOT
switches to the standard lag error limit.
Parameters
Q:
Lag error limit – default: 1
■ H=1: Standard lag error limit
■ H=2: Lag error limit 2
Activate zero offsets G980
”Activates” the workpiece zero point and all zero point shifts.
Traverse paths and position values are referenced to the distance
tool tip – workpiece zero point, while taking the zero point shifts
into consideration.
Activate zero offsets, tool lengths G981
”Activates” the workpiece zero point, all zero offsets and the tool
dimensions.
Traverse paths and position values are referenced to the distance
tool tip – workpiece zero point, while taking the zero point shifts
into consideration.
