12.0 MACHINE START-UP
Machine start-up consists in switching on and re-positioning axes, if required.
12.1 POWER-ON
To switch on the machine, follow this procedure:
1 - Turn the main switch, on the front panel of the machine, to 1.
2 - Make sure that the two emergency red keys ("mushroom") have been raised.
Wait until the power-on self test has been completed, then follow this procedure:
3 – Press the white ON
key placed on the operator’s panel.
The key now lights up and the machine is switched on.
For some machines, axes reference may be required before performing any other operation.
12.2 EXECUTION OF AXES REFERENCE
All axes, apart form X, are absolute axes. Reference points are therefore established the first time the
machine is started, if a major breakdown has occurred or if the measuring system has been changed
(from mm to inches)
1 – Press the axes reference key, placed on the operator’s panel, below the screen
The led corresponding to the key of the axis that must be re-positioned will flash. This might be: X
Make sure that the sliding guard is closed and locked and that the axes potentiometer is active i.e. set on
a value either than zero.
Make sure the X-axis is not positioned near the limit switch. Check for any interference that may lead to
impacts, then press the keys highlighted by the leds. The machine will then re-position all the axes and,
once movements are over, leds will be off whereas the machine will be ready to operate.
12.3 WRITE PROTECTION KEY
To store and to modify programmes and machine data, the protect key placed on the operator’s panel is
to be in horizontal position. In the remaining cases (correctors, origins, etc.) the key position is not
important.
