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 monitor-
ing and limitation by
Braking time 632
are deactivated. The braking current will be
impressed until the controller en
able control signal (S1IND/STOA and S7IND/STOB)
becomes logical 0 (low).

To avoid current surges, which can possibly lead to a fault switch-off of the frequen-
cy 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
Time Constant 227.

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

. 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.

12.4 Auto Start
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, machines and pro-
duction goods.
In addition to that, all specific regulations relevant to the application as well all na-
tional directives are to be complied with.
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 Opera-
tion mode
651, the frequency inverter accelerates the drive after applica
tion of the
mains voltage. The controller enabling signal and the start command are necessary
according to the regulations. When the motor is switched on, it is accelerated accord-
ing 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).
