Movement with an electronic handwheel
7.3.2 Path handwheel
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 (mill) or Z axis (lathe).
Feature setting
This feature must be managed from the PLC.
To activate or cancle the "Path jog" work mode, act upon the logic CNC input "MASTRHND" M5054.
M5054 = 0 "Path JOG" function off.
M5054 = 1 "Path JOG" function on.
To indicate the type of movement, use CNC logic input "HNLINARC" M5053.
M5053 = 0 Linear path.
M5053 = 1 Arc path.
For a linear path, indicate the path angle in the MASLAN variable (value in degrees between the
linear path and the first axis of the plane). For an arc, indicate the arc center coordinates in the
MASCFI, MASCSE variables (for the first and second axes of the main plane).
Variables MASLAN, MASCFI and MASCSE may be read and written from the CNC, DNC and PLC.
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 handwheels starts working in "path
handwheel" mode. The one associated witht the X axis if mill model or the one associated with
the Z if lathe model
The next example uses the [O2] key to activate and deactivate the "path handwheel" mode and the [O3]
key to indicate the type of movement.
DFU B29 R561 = CPL M5054
Activate or cancel the "path handwheel" mode.
DFU B31 R561 = CPL M5053
Select the type of movement; straight section or arc section.
