User's manual
An EMERGENCY STOP switch is located on the milling unit control panel
that enables the unit to be stopped as quickly as possible.
The EMERGENCY STOP switch must always be freely accessible.
NOTE
The main power switch on the unit has no EMERGENCY STOP function.
Position of the EMERGENCY STOP switch:
The EMERGENCY STOP switch is located on the front panel beneath the
touch screen.
An EMERGENCY STOP switch is located on the right side of the milling unit
beneath the control panel. Pressing the switch interrupts the power supply to
the power electronics (motor output stages) and the frequency converter for
the main spindle drive. The standstill occurs after stop-category 1 (controlled
standstill and subsequent interruption of the energy supply to the drives).
Location of the EMERGENCY STOP switch:
The EMERGENCY STOP switch is located on the right, beneath the control
panel.
Always be aware that:
• The EMERGENCY STOP switch must always be freely accessible.
• The milling unit main switch does not include an EMERGENCY STOP
function!
• The EMERGENCY STOP switch does not protect against an unexpected
milling unit start!
NOTE
After actuating the EMERGENCY STOP switch, the mains power supply is
still connected. Only the operating voltage for the motor output stages and
the milling spindle is interrupted.
When the unit is running the lid is locked and cannot be opened. The lid
must be neither removed nor modified. The lid protects from dust and
reduces grinding noise is a lid that enables access to the working area of the
unit.
The lid is monitored. If the lid is open the unit controls will not start.
When the unit is in operation the lid is locked and can only be opened when
all unit axes and spindles are at a standstill.
