WARNING
LOSS OF CONTROL
• When designing the control of the installation, the manufacturer should keep in
mind the implications of a potential failure in control paths and, for certain critical
functions, provide a method for returning to a safe state during and after the failure
of a control path.
Examples of critical control functions are:
EMERGENCY STOP, restricting the final position, network interruption and re-
starting.
• Separate or redundant control paths must be available for critical functions.
• Follow accident prevention instructions and all applicable safety directives.
• Any installation in which the product described in this manual is used must be
carefully and minutely checked to ensure that it is operating correctly, before it is
switched on.
If these precautions are not taken, the result could be death or serious injury.
WARNING
UNBRAKED MOVEMENT
In the event of a loss of power to the power stage, the motor is no longer braked in
a controlled way and could cause damage.
• Prevent access to the risk area..
• If necessary, use a damped mechanical stop or a service brake.
If these precautions are not taken, the result could be death, serious injury or
damage to equipment.
