5.4 Behaviour of the motor controller in the event of an interruption or
disconnection
5.4.1 Holding brake
The holding brake is used during operation to hold the motor/drive position when at a state of rest.
The function of the holding brake can be controlled via the following:
– Release holding brake:
• Enable output stage (DIN4) and c ontroller ( DIN5)  page 101.
– Loc k holding brake:
• Switch off output stage enable (DIN4)  page 107.
• Switch off controller enable (DIN5)  page 108.
• Interrupt mains supply  page 106.
The holding brake is configured in the Festo Configuration Tool (FCT) via the selection of the motor type.
When the holding brake has been c onfigured, the time delays in the brake control are activated and can
be parameterised.
Note
Using the holding brake
The holding brake is not suitable for braking the motor or payloads in the event of a
power interruption or if the motor controller has been switched off. Non-intended use of
the holding brake will result in increased wear of the holding jaws and a reduction of the
overall holding effect. A secure holding function is therefore no longer guaranteed.
