290 HEIDENHAIN Technical Manual MANUALplus 620
3.28.3 HRA 110 handwheel adapter
With the handwheel adapter you can connect two or three HR 150 panel-
mounted handwheels to the MANUALplus 620.
The first and second handwheels are permanently assigned to two axes
through MP_selectAxes (CfgHandwheel). The third handwheel can be
assigned through a selection switch (option). You also use MP_selectAxes to
define the axes for the third handwheel. (See "MP_selectAxes" on page 1338.)
An additional switch enables you to select, for example, the interpolation fac-
tor for the handwheels. In the PLC you must evaluate the current position of
the handwheel selection switch and activate the corresponding interpolation
factor with Module 9036.
