5.3.2 System integration in the plant control system
Connection – brake
The brake application time of the brake used should not exceed 25
ms.
Switch the brake directly and not via the PLC.
The respectively valid safety guidelines for motor-brake activation
must be complied with.
When using SEW motors, Expert-Tünkers recommends the use of
a type BMKB1.5 brake rectifier.
If a brake rectifier, other than type BMKB1.5 is used, then it must
always be wired on the direct current and alternating current sides
so that the brake can work with fast application.
If motors from different manufacturers are used, then the wiring
must be adapted in accordance with the specifications.
