Release brake

The Open brake function in operation mode 41 enables the activation of a corre-sponding unit via the
digital control output. The function uses both the control commands via the contact inputs and the set
starting and stopping behavior for controlling the digital output.
According to the configured starting behavior, the output is switched on when the magnetizing of the
motor is finished. When the
7.3.2 "Starting behavior".
The stopping behavior of the drive depends on the configuration of the parameters
630. See chapter 7.3.3 "Stopping behavior".
If stopping behavior 2 or 5 with stop function is selected, the drive is controlled to zero speed and the
digital output is not switched off. In the other operation modes of the stop behavior, the control of the
brake is possible. At the start of a free coasting of the drive, the digital output is switched off.
This is similar to the behavior in the case of stopping behavior with shutdown. The drive is
de-celerated and supplied with current for the set holding time. Within the set holding time, the con-
trol output is switched off and thus the brake activated.

Current limitation

Operation modes 15 to 19 link the digital outputs and the relay output to the functions of the intelli-
gent current limits. The reduction of power by the set figure in percent of the rated current depends
on the selected operation mode. Accord-ingly, the event for intervention of the current limitation can
be output via the op-eration modes of the digital outputs. If the function of the intelligent current
limits is deactivated within the sensorless control, operation modes 16 to 19 are switched off in the
same way.

External fan

Operation mode "43 - external fan" enables the control of an external fan. Via the digital output, the
fan is switched on as soon as the

Control of Brake
Operation mode "41 - Open brake" switches off the digital output as-
signed to the function immediately. The mechanical brake is activated.
Operation mode "41 - Open brake" switches off the digital output as-
signed to the function when the

Operation mode "41 - Open brake" leaves the digital output assigned to
the function switched on. The mechanical brake remains open.
Operation mode "41 - Open brake" switches off the digital output as-
signed to the function when the
