2 Manual Operation and Setup
Using the HR 330 electronic handwheel
The HR 330 is equipped with an enabling switch. The enabling switch is
located opposite the side with the knob and the EMERGENCY STOP
switch. The machine axes can only be moved when the enabling switch is
depressed.
• The enabling switch is automatically depressed when the handwheel is mounted on the machine.
• Mount the handwheel on the machine on the magnetic pads such that it cannot be operated unintentionally.
• When you remove the handwheel from its position, be careful not to accidentally press the axis direction keys
while the enabling switch is still depressed.
