Start-Up - ABB ACS380 Hardware Manual

Start-up

Set the following parameters:
1. Disable the overvoltage control of the drive with parameter 30.30 Overvoltage
control.
2. Set the source of parameter 31.01 External event 1 source to point to the digital
input where the thermal switch of the brake resistor is wired.
3. Set parameter 31.02 External event 1 type to Fault.
4. Enable the brake chopper by parameter 43.06 Brake chopper enable. If Enabled
with thermal model is selected, set also the brake resistor overload protection
parameters 43.08 and 43.09 according to the application.
5. Check the resistance value of parameter 43.10 Brake resistance.
With these parameter settings, the drive generates a fault and coasts to a stop on
brake resistor overtemperature.
WARNING! Disconnect the braking resistor, if it not enabled in the parameter
settings.
