WARNING
Dangerous movements! Danger to life, risk of injury, serious injury or
property damage!
● 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 functions 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 possible 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 STOP switches in the immediate reach of the op‐
erator. Before commissioning, verify that the EMERGENCY STOP equip‐
ment works. Do not operate the machine if the EMERGENCY STOP
switch is not working.
● Prevent unintended start-up. Isolate the drive power connection by means
of OFF switches/buttons or use a safe starting lockout.
● 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 axis,
– adding an external braking/ arrester/ clamping mechanism or
– ensuring sufficient equilibration of the vertical axis.
● 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 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.
