The field-orientated control modes are based on a cascade control and the calculation
of a complex machine model. The various control functions can be supplemented by
special functions specific to the application.

17.7.1 Motor Chopper

The field-orientated control modes contain the function for adapted implementation of
the generator energy into heat in the connected three-phase machine. This enables
the realization of dynamic speed changes at minimum system costs. The torque and
speed behavior of the drive system is not influenced by the parameterized braking
behavior. The parameter
switch-on threshold of the motor chopper function.
No.
507 Trigger Threshold
The parameter
the maximum DC link voltage which the mains can generate and the maximum admis-
sible DC link voltage of the frequency inverter.
If the parameter
DC link voltage, the motor chopper cannot become active, the motor chopper is
switched off.
If the set
mains can generate, error message F0706 (chapter "Error Messages") is displayed
when the frequency inverter is switched on.
