PH10 Operating Modes

The PH10 system can operate in one of two modes:
• Manual mode
• Automatic mode

Manual mode

In manual mode the optional HCU1 hand control unit is used to control head and probe functions.
If the HCU1 is connected to the PHC10-3 controller when power is applied to the system, the system will enter manual mode.

For further information refer to the HCU1 user's guide (Renishaw part number H‑1000‑5016).

Automatic mode

In automatic mode the system is under the control of the CMM computer. The HCU1 cannot be used to control head or probe functions in automatic mode.

With no HCU1 fitted when power is applied to the system, the system will enter automatic mode. The system must be switched to manual mode under CMM control (and an HCU1 connected) for operation under manual mode.

Please refer to the documentation provided by your CMM supplier for further details on controlling the PH10 series of heads using the CMM computer.


DO ensure that the head is mounted as rigidly as possible in the CMM’s quill.
DO take care to avoid collisions between the head and workpiece or CMM bed.
DO ensure that the head is moved clear of any obstruction before requesting a position change.
DO NOT apply force to any moving parts of the head.
DO NOT move the head axes by hand when locked or unlocked.
