stopped if no stop command is present in the new operation mode.
19.4 Brake chopper and brake resistance
The frequency inverters feature a brake chopper transistor. The external brake resistor is connected
to terminals Rb1 and Rb2. The parameter Trigger Threshold 506 defines the switch-on threshold of
the brake chopper. The generator output of the drive, which leads to the increase in the DC link
voltage, is converted to heat by the external brake resistor above the limit set via parameter Trigger
Threshold 506.

The parameter Trigger Threshold 506 is to be set in such a way that it is between the maximum DC
link voltage which the mains can generate and the maximum admissible DC link voltage of the
frequency inverter.

If the parameter Trigger Threshold 506 is set larger than the maximum admissible DC link voltage,
the brake chopper cannot become active, the brake chopper is switched off.
