Movement with an electronic handwheel
6.2.3 Feed handwheel mode
Usually, when making a part for the first time, the machine feedrate is controlled by means of the
feedrate override switch.
From this version on, it is also possible to use the machine handwheels to control that feedrate. This
way, the machining feedrate will depend on how fast the handwheel is turned.
The following CNC variables return the number of pulses the handwheel has turned.
HANPF provides the number of pulses of the 1st handwheel.
HANPS provides the number of pulses of the 2nd handwheel.
HANPT provides the number of pulses of the 3rd handwheel.
HANPFO provides the number of pulses of the 4th handwheel.
This feature must be managed from the PLC. Usually, this feature is turned on and off using an external
push button or key configured for that purpose.
