10.5 Integral handwheels HR 150 with handwheel adapter HRA 110

MP7640 = 5
If the step switch is used for the selection of the interpolation factor (S1) then inputs I160 to I167
must be evaluated in the PLC and the result must be displayed with the aid of PLC module 9036.
The third handwheel can be assigned to any desired axis. MP7645.2 defines whether the axis for
the third handwheel is selected with the axis selector switch (switch S2, see MP7645.0) or is
permanently assigned in machine parameter MP7645.1.
MP7645 Initializing parameters for handwheel
MP7645.0 to MP7645.2 have the following meaning when an HRA 110 is connected:
MP7645.0 Third handwheel assigned by axis selector switch

If no axis selector switch is connected (see also MP7645.2) the third handwheel is assigned an axis
according to the input value of MP7645.1.
MP7645.1 Handwheel #3 assigned by machine parameter
Entry: 0 to 255
1 = X axis
2 = Y axis
4 = Z axis
8 = 4th axis
16 = Axis 5
MP7645.2 Handwheel #3 assigned by axis selector switch or MP7645.1
Entry: 0 to 255
0 = Assigned by axis selector switch according to MP7645.0
1 = Assigned by MP7645.1
The axis selector switch only transmits data to PLC inputs I168 to I175.
The axis selector switch can therefore be used for other functions.
MP7645.3 to MP7645.7 are not assigned
