5.10.1 Setting the voltage source for braking operation
The voltage threshold for braking is set by means of the mains voltage (C00173
) and the
lowered brake chopper threshold (C00174
).
 This "brake chopper threshold" is preset as follows so that it is higher than the specified
mains voltage (C00173
):
 This brake chopper threshold can be reduced by 0 ... 150 V by means of C00174
.
Example:
 A 400 V device has a maximum mains voltage of 420 V AC.
– Maximum stationary DC-bus voltage: 420 V AC * 1.414 = 594 V DC
– C00173
has been set with the selection "0" for 400 V AC mains.
 This means that C00174
can be set to a maximum of 131 V DC (725 V DC - 594 V DC).

 Stop!
The brake chopper threshold resulting from C00173 and C00174 must not
exceed the stabilised DC-bus voltage!
