Hazard caused by coasting of the drive

Hazard caused by coasting of the drive. Without a 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. As an alternative, you must equip the drive with a safety brake.
• The additional protective covers 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 alternative, you must determine the access or intervention time and then calculate and observe the resulting safety clearance.
