Reference Point Return Check - G27 The G27 is used when it is necessary to move to the primary reference point and verify that the machine axes did reach the reference point. •
In the G27 block, axis coordinates are programmed that define the position of the primary reference point. These coordinates do not represent an Intermediate Point as with G28 and G30.
•
When the G27 block is executed, the machine axes move to the primary reference point non-linearly at the rapid traverse rate. -
If all axes reached their primary reference point, the Reference Position lights turn On and the next program block is executed.
-
If an axis does not reach its primary reference point, the respective Reference Position light does not turn On and an alarm is generated.
•
The axes coordinates of the G27 block can be programmed in the absolute (G90) or incremental (G91) mode.
•
To avoid overtravel alarms: -
Tool length compensation must be canceled by programming G49 after in the G27 block.
-
Cutter Compensation C must be canceled by programming G40 after the G27 block.
