A
risk
assessment
must
be
prepared for the installation or machine, with its
specific conditions,
in
which the components of the electric drive and control
system are installed.
As a result of the risk assessment, the user must provide for monitoring func-
tions and higher-level measures
on
the installation side for personal safety. The
safety regulations applicable to the installation or machine must
be
taken into
consideration. Unintended machine movements or other malfunctions are pos-
sible if safety devices are disabled, bypassed or not activated.
To
avoid
accidents,
injury
and/or
property
damage:
• Keep free and clear of the machine's range of motion and moving machine
parts. Prevent personnel from accidentally entering the machine's range
of motion by using, for example:
Safety fences
Safety guards
Protective coverings
Light barriers
• Make sure the safety fences and protective coverings are strong enough
to resist maximum possible kinetic energy.
• Mount emergency stopping switches
in
the immediate reach
of
the oper-
ator. Before commissioning, verify that the emergency stopping equip-
ment works.
Do
not operate the machine if the emergency stopping switch
is
not working.
• Prevent unintended start-up. Isolate the drive power connection by means
of
OFF switches/OFF buttons or use a safe starting lockout.
• Make sure that the drives are brought to 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/clampi
ng
mechanism or
ensuring sufficient counterbalancing of the vertical axes.
• The standard equipment
motor
holding
brake
or
an
external holding brake
controlled by the drive controller
is
not
sufficient
to
guarantee
personal
safety!
• Disconnect electrical power to the components of the electric drive and
control system using the master switch and secure them from reconnec-
tion ("lock out") for:
Maintenance and repair work
Cleaning of equipment
Long periods of discontinued equipment use
• Prevent the operation of high-frequency, remote control and radio equip-
ment near components
of
the electric drive and control system and their
supply leads.
If the use of these devices cannot
be
avoided, check the
machine or installation, at initial commissioning of the electric drive and
control system, for possible malfunctions when operating such high-fre-
quency, remote control and radio equipment
in
its possible positions
of
normal use. It might possibly
be
necessary to perform a special electro-
magnetic compatibility
(EMC) test.
