» malfunction of sensors, encoders and monitoring devices
» defective components
» software or firmware errors
Dangerous movements can occur immediately after equipment is switched on or even after
an unspecified time of trouble-free operation. The monitoring in the drive components will
normally be sufficient to avoid faulty operation in the connected drives. Regarding personal
safety, especially the danger of bodily harm and material damage, this alone cannot be relied
upon to ensure complete safety. Until the integrated monitoring functions become effective,
it must be assumed in any case that faulty drive movements will occur. The extent of faulty
drive movements depends upon the type of control and the state of operation.
Dangerous movements! Danger to life, risk of injury, severe bodily harm or material damage!
»
For the above reasons, ensure personal safety by means of qualified and tested higher-
level monitoring devices or measures integrated in the installation. They have to be
provided for by the user according to the specific conditions within the installation and
a hazard and fault analysis. The safety regulations applicable for the installation have to
be taken into consideration. Unintended machine motion or other malfunction is possible
if safety devices are disabled, bypassed or not activated.
To avoid accidents, bodily harm and/or material damage:
»
Keep free and clear of the machine’s range of motion and moving parts. Possible mea-
sures to prevent people from accidentally entering the machine’s range of motion:
use safety fences
use safety guards
use protective coverings
install light curtains or light barriers
»
Fences and coverings must be strong enough to resist maximum possible momentum.
»
Mount the emergency stop switch in the immediate reach of the operator. Verify that the
emergency stop works before startup. Don’t operate the device if the emergency stop is
not working.
»
Isolate the drive power connection by means of an emergency stop circuit or use a safety
related starting lockout to prevent unintentional start.
»
Make sure that the drives are brought to a safe standstill before accessing or entering
the danger zone.
»
Additionally secure vertical axes against falling or dropping after switching off the motor
power by, for example:
mechanically securing the vertical axes,
adding an external braking/ arrester/ clamping mechanism or
ensuring sufficient equilibration of the vertical axes.
The standard equipment motor brake or an external brake controlled directly by the drive
controller are not sufficient to guarantee personal safety!
» Disconnect electrical power to the equipment using a master switch and secure the
switch against reconnection for:
maintenance and repair work
cleaning of equipment
long periods of discontinued equipment use
» Prevent the operation of high-frequency, remote control and radio equipment near elec-
tronics circuits and supply leads. If the use of such devices cannot be avoided, verify the
