Principle
8.15.4 Automatic tool recognition
Automatic tool identification is possible with the Balluff tool identification
system (BIS).
Please contact HEIDENHAIN for further information.
8.15.5 Controlling the tool changer
You program the control of the tool changer in the PLC.
This includes:
 Positioning of the changing arm and carousel
 Tool change sequence
The NC handles the tool management. This includes:
 Tool life
 Pocket assignment
 Evaluation of the TOOL DEF blocks
 Evaluation of the TOOL CALL blocks
The NC and PLC communicate through markers and words.
For execution of the TOOL CALL block, the NC takes the tool geometry data
from the tool table:
 Activate with M4538 the geometry of the tool defined in W264. With this
marker you make sure that the current tool geometry is always active even
if the tool change sequence is canceled.
CAUTION: Activate only together with an M/S/T/Q strobe or if M4176 = 0
(control-in-operation display is lit or blinking)!
