11.11.2 "Automac" brake mode (automac operaon)
In automac operaon, the inverter automacally released the holding brake when the motor
is started. In the stopped state, the holding brake is closed.
DANGER!
Manual release of the holding brake
Also in automac operaon, a manual release of the holding brake is possible. 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 secon is
switched o.
▶
The responsibility for a manual release of the holding brake has the external trigger source
for the "Release holding brake" command!
