1502 HEIDENHAIN Technical Manual iTNC 530 HSCI
8.8 Electronic handwheel
The following handwheels can be connected with HEIDENHAIN controls:
 One panel-mounted HR 130 handwheel, or
 Three HR 150 panel-mounted handwheels via the HRA 110 handwheel
adapter, or
 Up to two HR 410 portable handwheels, or
 Up to two HR 520/HR 420 portable handwheels with display, or
 One HR 550 portable wireless handwheel with display
For information on the operation of the electronic handwheel, see the User's
Manual.
 In MP7640, enter the type of handwheel connected to the control. If you
enter a value greater than zero and no handwheel is connected, the error
message HANDWHEEL? appears.
 If you use more than one handwheel together with the HRA 110 handwheel
adapter, enter in MP7650 for each axis the counting direction of the
individual handwheels. If you use only one handwheel, enter the counting
direction in bit 0.
Shock or vibrations can cause a slight motion at the handwheel and produce
an unintentional axis movement. In this case:
 Enter a threshold sensitivity in MP7660.
With W1062/W1176 you can disable the handwheel pulses for specific axes,
if more than one handwheel is used in connection with the HRA 110
handwheel adapter. If the marker M4576 is set, all axes are disabled. If it is
reset, W1062/W1176 applies. If only one handwheel is used, a selectable axis
can be disabled with W1062/W1176.
The subdivision factor specifies the traverse per handwheel revolution:
 For the HR 130 or HRA 110, choose the HANDWHEEL operating mode and
enter a subdivision factor for each handwheel. To ensure that the rapid
traverse rates specified in MP1010.x are not exceeded, the smallest
possible input step is preset by the control.
 For the HR 130 or HR 110, with MP7641 you specify whether the
subdivision factor is entered directly through the TNC keyboard or via
PLC Module 9036.
