1.2.2 Closing the movable protective devices

The movable protective devices are manually closed, but are not yet
locked.

Locking of the safety doors is effected as follows:

• pressing the appropriate buttons on the machine control panel
again

• by selecting the reverse function in the respective set-up screen

The voltages are reconnected upon locking. However, the machine
does not start autonomously
(it has to be started actively via NC Start.)

1.2.3 Emergency unlocking of the voltage-free locked protective devices

If there is a voltage failure, all protective devices generally are locked
by means of an Euchner safety switch.

Display LED:

• LED "Power" (green) lights up: ASi voltage on

• LED "Fault" (red) lights up: ASi fault

• Red LED flashing: unlocked

• LED lights up red: open

• Red LED off: closed and locked

• LED lights up green: locked

• Green LED off: not locked

no voltage applied => no LED lights up = locked

If safety doors have to be opened, they can be emergency unlocked
as follows.

• Unscrew safety screw (1)

• Unlock the padlock (2) by turning it with a suitable screw driver.

• The protective device is now unlocked and can be opened.

Reset emergency unlocking status in reverse order.

1.2.4 Gravity (drop) lock

Persons can be locked into the machine (maintenance and work

area) if the safety doors are closed unintentionally.
Risk of severe injuries or death for any persons locked inside the
danger area of the machine if the machine is started unintentionally!
The risk emerges if prior to starting the machine an open or unse­cured access door to the maintenance or work area is closed or
closes independently.

For this reason gravity-actuated door locks are installed on critical
safety doors that prevent any accidental closing of safety doors to the
danger areas.
They can be secured with a padlock.
Since the machine can not be started with open safety doors it can
therefore not be started unintentionally.

1.3.4 Safe stop

The feedback control of the drives is switched off. The pulses are

suppressed. The motor is disconnected from the energy supply.

1.3.5 Test stop

After switching on the machine, and after request ‘Unlock door’ after

8 hours, forced dynamic sampling of the switch-off path (test stop) is
carried out.
The safety system “Safety Integrated” carries out an examination of
all the static signals and data as well as safety-related components.

If the test stop is not passed the machine is switched into "safe
stop" mode. The component which caused the test stop failure
must be replaced instantly. In order to be able to open the safe­ty doors the media must be switched off.

1.6 Protective devices for machine components

These protective devices are for the purpose of guarding connected

devices or internal parts of the installation.

1.6.1 Electrical safety devices

The following fuse elements are in use:

• motor protection switch

• Automatic circuit breakers

1.6.2 Excess temperature

All feed motors are fitted with excess temperature sensors to prevent

damage caused by overheating.

If the motor temperature of 72 °C is reached, the machine must
be stopped due to temperatur e pre-warning signal, then the
spindle is stopped after 2 seconds.

1.6.3 Lubrication and cleaning program

Cleaning program

runtime: approx. 3 min

The CLEAN_PRG must be run once a day. This program is stored in
the parts program folder and has to selected manually. Precondition
is that the tool in the spindle is permitted for maximal speed.
Starting this program will initiate the following process.

• All the magazine tool pockets are cleaned.

• All the tool shafts are brushed.

• Then the X and Y axis trace the complete stroke one after an-

automatic cleaning prog ram

If CLEAN_PRG is not run a reduced lubricating and cleaning pro­gram is run automatically with the first NC start of the day. The Y­axis is not moved. The Z-axis traverses back into the tunnel. If the
spindle has been idle for over 4 hours a spindle warm-up cycle is
started by the NC start.

Prior to starting the cleaning program make sure that
this program can be carried out collision-free. Eliminate
any interference contours (clamping fixture, workpiece,
etc.) in the work area.

The Z-axis is to be advanced all the way once a day to
strip off the axis guide.

Safety cut-out

1.8 Safety cut-out

Operating control se­quence:

Prior to any works on mo to rs or other electrical equipment it is
essential to switch off the main switch and to secure it against
unintentional reconnection by using a padlock.

Safety shut-down means that the machine is switched off for safety

reasons prior to beginning any service, repair or similar work.

Make sure that a safety cut off is performed only at the end of a pro-

gram or cycle or when the machine is the service position, except in
the event of an emergency. This prevents damage to tools and
workpieces and the machine can be restarted normally.

In the service position any hanging axes can be supported or se­cured with locking pins, and therefore any maintenance works car­ried out safely.

Prior to starting operation all vertical axes must either be fully
lowered or prevented against dropping.

Foot switch for releasing the locating pin.
Once the locating pin is released the pallet can be rotated by hand.
By letting go the foot switch and with correct pallet position (0°, 90°,

180°, 270°) the locating pin is automatically inserted into the pallet
and prevents the pallet from twisting.

Functions on the setup station (clamp/unclamp, pallet change) can
only be performed if the pallet is in 0° position.

The GROB Company has no influence on the constructional de­sign of the clamping fixtur e and the fluid connection of hydrau­lic system of the machine. In case of malfunction, escaping hyd­raulic fluid under high pressure as well as crush and shear
points on the clamping fixture can cause injury.

The hydraulic clamping system is equipped with prototype­tested components able to withsta n d a maximum pressure of
250 bars in case of malfunction.

Safety instructions to minimize potential hazards

► Any devices/clamping fixture must be designed for maximum

pressure.

► The device/clamping fixture must not exceed the maximum part

size.

► Proceed with utmost care when designing, tooling and clamping

the parts.

► Check the device/clamping fixture after assembly with a minimum

pressure of 250 bars on a test stand outside the machine. How­ever, if a hydraulic fluid leak occurs, stop the test immediately and
ascertain the cause.

► Check the device/clamping fixture after tooling with closed work

area door with maximum system pressure of the machine, and
watch for leaking hydraulic fluid. However, if a hydraulic fluid leak
occurs, stop the test immediately and ascertain the cause.

► Prepare an operating instruction for the operators.
► Train and instruct the operators properly.
► Instruct new/temporary workers on the machine about the risks.
► Wear personal protective equipment (eye protection, hand guard).
► The device/clamping fixture and the machine must be operated by

one person only.

► Ensure safe placement of the machine.
► As far as possible, close the work area door before starting the

clamping process.

► Only start the clamping process after making sure, that no parts

of the body are within the clamping or swing radius of the de-

2.11.2 Axis switch

Axis limit switches (soft­ware)

All CNC axes that are limited by limit positions are equipped for each
axis direction with one software limit position each. No actual swit­ches exist, but an internal control comparison is effected between the
relevant absolute axis position and a range limit defined in the ma­chine data. If this range limit is approached, the axis is disabled in
this direction and this is displayed on the CNC screen.

Enable of home position
Z-axis

During the homing process the actual position of the Z-axis is che­cked for an enabling area. This area is defined in the
Z_ENA_HOMEPOS parameter.

If movement to home position is not possible the Z-axis must be mo­ved to an area larger Z_ENA_HOMEPOS in setup mode.

2.11.3 Asynchronous axes

Asynchronous axes are auxiliary or secondary axes that are not in-

terpolated with the main axes but travel independently of them.

2.11.4 Referencing the axes

All the axes of the machining unit are equipped with an absolute en­coder. Therefore they will not lose their positions and must not be re­ferenced in case of power failure.

ensure correct machining they must be "warmed up" (expansion
of materials, change in viscosity of media...) To achieve this as
fast as possible, there is a warm-up program. To start the pro­gram the machine must be empty.

• Automatic clamping program, setup station: If "ON" is prese-
lected here, and if the button "Confirm loading" on the setup sta­tion is pressed a stored clamping program will be called. Any
machined parts are unclamped automatically before the setup
station door is unlocked. If "OFF" is selected here, the couplings
required for the clamping process must be selected by pressing
the button before any acknowledgement is made here.

Concerning "Automatic clamping program setup station"

In the program list the machining programs are assigned a type
number. If "Automatic clamping setup station" is active, this type
number is also evaluated for clamping and unclamping.
The control system searches automatically for a clamping or un­clamping program with the name:

• CLAMP_"Type No.“ • UNCLAMP_"Type No.“
in folder "Subprograms".

They are called for clamping after "Acknowledge loading", and for
unclamping after "Ready signal at setup station".
