7.9 Tool correction
This function makes "Referencing on the fly" possible for position followers. This is necessary
if:
•
The tool drifts because the feed constant is not exactly known.
•
Referencing is not possible when the machine starts due to process reasons.
When the Activate tool correction parameter = 1 is activated, the expected setpoint position
is compared with the actual position when the tool-side sensor is triggered.

0x5041:120
A corrective movement is generated to compensate for the determined position error. The
position error is compensated for within the configured correction window.
Set the parameter Activate tool correction = FALSE to calculate the error but not execute a
correction.
