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 opening of the holding brake lies with the user of the external trigger source for the "Release holding brake" command.

Example
A PLC program of a PLCopen control can, for instance, trigger several commands for state changes in a row by the level change at the bRegulatorOn input of the "MC_Power" block.
In the mentioned example, these device commands are "Switch-off" and "Switch on" in this order.
