Manual and automatic modes
Manual and automatic modes are selected by the CMM computer.
Manual mode
In manual mode, the HCU2 is used to control the motorised head, to set probe functions or send teach point commands.
The display indicates MANUAL.
If the HCU2 is connected to the motorised head controller before power is applied, the system will power up in manual mode.
Automatic mode
In automatic mode the motorised head system is under control of the CMM computer.
The display indicates AUTO.
The HCU2 displays information, but it is not possible to use it to move the head or set probe functions.
If the HCU2 is not connected to the motorised head controller when power is applied, the system will enter automatic mode.
Jog move
This feature is used to move the probe head in single steps.Press and immediately release the appropriate direction key.
The head will unlock and the LCD will display ACTIVE. The head will rotate by a single 7.5° step.
If the direction key is pressed again before the head begins to lock, the head will rotate by another 7.5° step.
If no further keys are pressed, the head will lock, the LCD will display READY and the motorised head will be ready for measurement.
Sweep move
This feature is used to move the probe head in one continuous movement.
Press and hold down the appropriate direction key.
The head will unlock, and the LCD will display ACTIVE. The head will rotate by a single 7.5° step.
After a short delay the head will continue to rotate in this direction until either the key is released or the axis limit is reached.
There will be another short delay, then the head will lock and the LCD will display READY.
Teach signal
The T (transmit) key is used to send a signal to the CMM computer.
The action and use of this signal are dependent on the integration of this function by your CMM supplier.
When the operator is “teaching” the CMM a sequence of positions to follow, the T key is pressed to signal that a required position has been reached. It can also be used to instruct the CMM computer to memorise the angle of the probe head during a teach cycle.
Please refer to the relevant CMM-specific documentation provided by your CMM supplier for details of the use of the T key.
