Handwheel Adapter Hra - HEIDENHAIN TNC 415 Technical Manual

10.5 Handwheel adapter HRA 110

The HRA 110 can be used to connect 2 or 3 handwheels HR 150 to one LE.
The first two handwheels are dedicated to axes X and Y. The third handwheel can be assigned to
axes X, Y, Z, IV or V using a step switch (optional) or machine parameters. (See "Handwheel" section
in chapter "Machine integration").
HR 150
max. 20 m
A second step switch (optional) can be used to select the interpolation factor for the handwheels.
The interpolation factor of the step switch must be evaluated in the PLC - it is displayed on screen
but cannot be altered with the keyboard.
However the interpolation factor can be set for specific axes without a step switch by using the
keyboard as before.
