Assignment of a trigger for the "Release holding brake" function.
Trigger = TRUE: Release holding brake (immediately).
Trigger = FALSE: no action.
Notes:
Function is only executed if the brake mode 0x2820:001 (P712.01) is
set to "Automatic [0]" or "Manual [1]".
CAUTION!
The manually triggered "Release holding brake" command has a direct
impact on the "Release holding brake [115]" trigger.
Thus, the holding
brake can be manually released if the power section is switched off!
The responsibility for a manual release of the holding brake has the
external trigger source for the "Release holding brake" command!

Example for operating mode
• Switch S1 starts the motor in forward direction of rotation. Switch S1 in the initial
position stops the motor again.
• Switch S2 releases the holding brake. For this purpose, in this example, trigger "Release
holding brake [115]" is assigned to the relay that switches the brake supply.
