WARNING
● A risk assessment must be prepared for the installation or machine, with
its specific conditions, in which the components of the 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 operator.
Before commissioning, verify that the emergency stop equipment 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 an emergency stop circuit 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 axes,
– adding an external braking/arrester/clamping mechanism or
– ensuring sufficient equilibration 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 drive and control
system using the master switch and secure them from 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 electric/electronic components of the drive and control
system and their supply leads. If the use of these devices cannot be
avoided, check the machine or installation, before initial commissioning
of the drive and control system, for possible malfunctions when
operating such high-frequency, remote control and radio equipment in
its possible positions of normal use. It might possibly be necessary to
perform a special electromagnetic compatibility (EMC) test.
