2.13 Safety regulations for programming
Before starting any program, including automatic homing, we recommend making sure that the portable
pad is enabled in order to be able to reduce speed and, if necessary, stop machine movements.
When running a program for the first time, disable spindle start-up (following the procedure described in
the relative section of the manual) and proceed at reduced speed using the potentiometer on the
keypad.
Respect the technological parameters for tools and machining, especially as regards machining speed
and the number of spindle revolutions.
Do not use the potentiometer to reduce or control speed during normal production.
2.14 Safety regulations for electrical maintenance
Knowledge of first-aid procedures for electrical accidents is required. Before starting maintenance on
electrical circuits, the person in charge of the work must check that all safety regulations have been
respected. Comply with current national laws and regulations regarding work on electrical systems.
•
All work must be carried out using only suitable and isolated tools.
•
Respect safety signs! Do not remove the safety signs.
•
Before starting work, adopt the precautions described below.
Follow this procedure:
STEP OPERATION RESULT
1
Remove voltage.
Turn the main switch to "0". When electrical power has been cut off, the
machine is not live. The connection area up
to the main switch is still powered.
2
Wait a few seconds before opening the
electrical cabinet. The condensator in the inverter loses charge
a few seconds after the main switch has
been turned off.
3
Adopt all safety measures required to
avoid start-up. Padlock the main switch.
4
Check that the electrical power has been
disconnected.
