Hazard caused by coasting of the drive
WARNING
Hazard caused by coasting of the drive. Without mechanical brake or if the brake is
faulty, a danger exists of the drive coasting to a halt.
Severe or fatal injuries.
•
If the coasting of the drive causes any application-specific dangers, you must
provide for additional preventive measures (e.g. guard with guard locking
device). The additional preventive measures must cover the danger zone until no
further danger to personnel exists.
•
The additional preventive measures must be designed and integrated so that
they meet the requirements determined in the risk assessment for the machine.
•
After activating the stop command, access to the machine must remain blocked
until the drive has reached standstill depending on the hazard involved. As an al-
ternative, you must determine the access or intervention time and then calculate
and observe the resulting safety clearance.
