The PHC10-2 controls any one of the PH10T, PH10M or PH10MQ heads based on commands received from either the CMM controller or the HCU1 (if fitted). In addition to this, the PHC10-2 interrogates the head and reports back:
the heads A and B positions,
any problems found
The PHC10-2 does not process any of the probe sensor signals. These are railed clean
through through the heads axes and controller to the probe interface.
