Contact-controlled:
If the parameter
Braking Time 632 is set to the value 0.0 s, the direct current brake is
controlled by the Start clockwise and Start anticlockwise signals. The time monitoring
and limitation by
Braking Time 632 are deactivated. The braking current flows up to
the logical status 0 (low) of the controller release (S1IND).

To avoid current surges, which can possibly lead to a fault switch-off of the frequency
inverter, a direct current may only be impressed into the motor after the motor has
been demagnetized. As the demagnetization time depends on the motor used, it can
be set with the parameter
Demagnetizing Time 633.
The selected demagnetizing time should be approximately three times the
Act. Rotor

The selected stopping behavior is supplemented by a current controller to control the
direct current brake. The PI controller checks the current impression of the set
Brak-
ing Current
631. The proportional and integrating parts of current controller can be
adjusted via parameters
Amplification 634 and Integral Time 635, respectively. The
control functions can be deactivated by setting the parameters to 0.

11.4 Auto Start
The Auto Start function is suitable for applications which permit a start at mains volt-
age by their function. By activation of the auto-start function via parameter
Operation
Mode
651, the frequency inverter accelerates the drive after connection of the mains
voltage. The controller release signal and the start command are necessary according
to the regulations. When the motor is switched on, it is accelerated according to the
parameterization and the reference value signal.
Operation mode 651 Function
0 - Off
The drive is accelerated, after application of the mains
voltage, as soon as the controller enabling signal and the
start command are switched from stop to start (edge
evaluation).
1 - Switched on
The drive is accelerated by the frequency inverter as soon
as the mains voltage is applied (level evaluation).
Warning! Comply with standard EN 60204 and VDE provision 0100 part 227 and
provision 0113, in particular Sections 5.4, protection against automatic
restart after main line voltage failure and voltage recovery, and Section
5.5, undervoltage protection.
Appropriate measures must be taken to exclude any risk for staff, ma-
chines and production goods.
In addition to that, all specific regulations relevant to the application as
well as all national directives are to be complied with.
