Motor holding brake

 DANGER

Risk of injury from hanging axes

The optional motor brake is a holding brake and does NOT provide sufficient protection for persons.

Hanging axes can fall and lead to severe injury.

Steps to prevent:

  • All hanging axes must be mechanically secured against falling with a fall arrester or a supplementary external brake, for instance.

  • People must not stand under hanging loads

 

NOTICE

Material Damage!

Material damage of the holding brake!

The brake optional integrated into the motor is a holding brake. The holding brake can be irreparably damaged if it is used as main brake.

Steps to prevent:

  • Make sure that the motor holding brake is open, when movement commands are sent to the motor.
  • Make sure that the motor holding brake only closes after the motor shaft has come to a standstill.

 

The motors can be optionally equipped with a motor holding brake (spring-loaded brake). The brakes are opened using 24 V DC (unsmoothed). The speed thresholds of the brake must not be exceeded by the application. The brake is connected directly to the AMK converter and is automatically controlled by the converter.

If the brake opens while the motor shaft is rotating (e.g. in the case of a mains failure), the operator of the machine subsequently has to ensure that the brake is fully functional before starting up the machine again.
