[5-16] Basic function "Brake control" (schematic diagram)
If the automatic operation (operating mode 2 or 12) is selected in C02580, the brake is
controlled automatically, i.e. if the multi-purpose positioning or another basic function is
activated which causes the drive to traverse, the brake is opened automatically and the
operation is enabled.
 Parameter setting: Tab Application parameters  dialog level Overview  Brake control
The basic function "Brake control" serves
to the wear free control and monitoring of
a holding brake.
In the simplest case, an optionally
available brake module is used.
Alternatively the holding brake can also be
controlled and monitored via the digital
