MCO-TCO work mode
2.4.4.2 PATH HANDWHEEL MODE
With this feature, it is possible to jog two axes at the same time along a linear path (chamfer) or circular
path (rounding) with a single handwheel.
The CNC assumes as the path handwheel the general handwheel or, when this one is missing, the one
associated with the X axis (MCO model) or Z axis (COO model).
This feature must be handled by the manufacturer of the machine.
While in handwheel mode and having selected the “path handwheel” via PLC (MASTRHND=1), the
CNC shows the following data:
The type of movement is set via PLC:
linear movement if
HNLINAR = 0
Arc movement if
HNLINAR = 1
When choosing a linear jog (upper drawing) , the angle of the path must be indicated and when
choosing a circular jog (lower drawing), the arc center coordinates must be indicated in radius.
To define these variables, press the [F] and, then, one of these keys:
Example: The [O2] key is used to activate or deactivate the "path handwheel" mode and the [O3] key
to indicate the type of movement.
DFU B29 R561 = CPL MASTRHND
[O2] activates and deactivates the "path handwheel" mode
DFU B31 R561 = CPL HNLINARC
[O3] Selects the type of movement, a straight line or an arc
Simultaneous handwheels
When selecting the Path Handwheel mode, the CNC behaves as follows:
•
If there is a General Handwheel, it will be the one working in Path handwheel mode.
The individual handwheels, if any, will remain associated with the corresponding axes.
•
If there is no General Handwheel, one of the individual handwheel starts working in Path
handwheel mode. The one associated with the X axis if MCO model or the one associated with
the Z if COO model.
