VI
Protection against dangerous movements
Warning
High acceleration forces at the connected actuators! Unde
sired movements can cause collisions and severe injuries.
Dangerous movements can occur through faulty control
ling of connected actuators, e.g. via:
unsafe or faulty circuitry or cabling,
faulty operation of the components,
errors in the measured value and signal generators,
defects or non−EMC−compliant components,
errors in the higher−order control system,
programming errors in user programs and projects.
Simply switching off the compressed air supply or load
voltage is not suitable for locking procedures. In the event
of a fault, this could lead to unintentional movement of the
drive.
Before doing mounting, installation and service work,
·
bring the system into a safe condition (e.g. by bringing
the drive into a safe position and deactivating the
controller).
Always make sure that the compressed air supply and
power supply are switched off and locked when working
in the machine area.
Make sure that no persons are in the operating range of
·
the drives or any other connected actuators.
Do not switch on the compressed air supply until the
·
system is correctly installed and parameterised.
