WARNING
LOSS OF COMMAND CONTROL
• When perfecting the command concept, the installation manufacturer must take
account of the possibilities for potential failure of command paths and provide, for
certain critical functions, the means of returning to safe states during and after the
failure of a command path.
Examples of critical command functions are:
EMERGENCY STOP, end position limiting, network outage and restarting.
• Separate or redundant command paths must be available for critical functions.
• Comply with the accident prevention instructions and all current safety directives.
• Any installation in which the product described in this manual has a central role
must be carefully and meticulously checked prior to commissioning to ensure it is
working properly.
Failure to comply with these precautions can result in death or serious injury.
WARNING
UNBRAKED MOVEMENT
In the event of a power outage and errors resulting in disconnection of the power
stage, the motor is no longer braked in a controlled way and can cause damage.
• Prevent access to the hazardous zone.
• If necessary, use a damped mechanical stop or a service brake.
Failure to comply with these precautions can result in death, serious injury or
damage to equipment.
