General safety information
Warning
Danger from unexpected movement of the axis
Accidental movements of the connected actuators can cause collisions, with serious
injuries. Dangerous movements due to incorrect control of connected actuators, for
example caused by:
–
untidy or faulty wiring/cabling
–
errors in operating the components
–
errors in the measured value and signal encoders
–
defective or non-EMC-compliant components
–
errors in the higher-order control system
Switching off the compressed air or load voltage is not a suitable locking method. In
case of malfunction, drives can travel unintentionally.
Before carrying out mounting, installation and maintenance work, place the system
in a safe status (e.g. by placing the drive in a safe position and locking it).
Make sure that no one enters the sphere of influence of the drives and actuators.
Switch on the compressed air only when the system has been professionally in
stalled and parameterised.
Note that the controlled brake/clamping unit alone is not appropriate for personal
protection.
Provide additional support to protect vertical axes from falling or sliding down when
the compressed air and load voltage are switched off, such as by:
–
mechanical locking of the vertical axis
–
external brake/clamping unit
–
sufficient counterbalance of the axis
Caution
Danger of injury due to incorrect handling of pressurised lines
Uncontrolled movements of the connected actuator technology and loose tubing can
cause injury to persons and/or damage to property.
Do not disconnect, open or cap pressurised lines.
Exhaust lines before dismantling (release compressed air).
Use suitable protective equipment (e.g. safety goggles, safety shoes).
