Parameterizing brake resistor
To remove excess braking energy from the DC link, a brake resistor can be connected to the 5
th
generation
of STOBER inverters. You will find information on the types available from STOBER and connection in the
configuration manual for the inverter.
Parameters
•
A21 Braking resistor R
[
Ω
]
•
A22 Braking resistor P [W]
•
A23 Braking resistor thermal [s]
are available for the settings.
Enter the value 0 in A22 and the activation of the braking resistor (brake chopper) is deactivated. Note that
the brake chopper continues working when most malfunctions occur. The malfunctions that cause the brake
chopper to be switched off are documented accordingly in chapter Diagnosis.
Inverters of size 3 have an internal braking resistor. To activate the internal brake resistor, enter
A21
= 30
Ω
and
A22
= 1000 W for example.
