    j | BA 14.0197 | 11/2010 Technical data Engagement time Short brake engagement times are vital for emergency braking. DC switching together with a suitable spark suppressor must therefore be provided. If the drive system includes a frequency inverter so that the brake is deenergised only when the motor is at standstill, switching on the AC side is also possible (not valid for emergency braking).

The friction lining and the mechanical brake components are subject to function−related wear. For safe and trouble−free operation, the brake must be checked and readjusted at regular intervals, and, if necessary, be replaced.

  • Page 82: Inspections

    j | BA 14.0197 | 11/2010 Maintenance/repair Inspections To ensure safe and trouble−free operation, spring−applied brakes must be checked and maintained at regular intervals. Servicing can be made easier if good accessability of the brakes is provided in the plant. This must be considered when installing the drives in the plant. Primarily, the necessary maintenance intervals for industrial brakes result from the load during operation.
