The smallest programmable interpolation factor depends on the specific machine tool. Your machine manual
provides more detailed information on this subject.
Using the HR 330 electronic handwheel
The HR 330 portable handwheel has an enabling switch that is located on
the side opposite to the star grip and the EMERGENCY STOP switch.
You can only move the machine axes when the enabling switch is
depressed.
• As long as the handwheel is attached to the machine tool, the enabling switch is automatically depressed.
• Attach the electronic handwheel to a steel surface with the mounting magnets such that it cannot be operated
unintentionally.
• Be sure not to press the axis direction keys unintentionally while the enabling switch is depressed when you
remove the handwheel from its position.
