8.1 Parameter setting
Short overview: Parameters for braking operation
8.1.1 Setting the voltage threshold for braking operation
The voltage threshold for braking operation is set via C00173 (mains voltage) and C00181 (reduced
brake chopper threshold). If the brake chopper threshold in the DC bus is exceeded, the brake
transistor is switched on.
