ABB ACS880-07 Hardware Manual page 255

Set the following parameters (ACS880 primary control program):
•
Disable the overvoltage control of the drive by parameter 30.30 Overvoltage control.
•
Set parameter 31.01 External event 1 source to point to the digital input where the
thermal switch of the brake resistor is wired.
•
Set parameter 31.02 External event 1 type to Fault.
•
Enable the brake chopper by parameter 43.06 Brake chopper function. If Enabled
with thermal model is selected, set also the brake resistor overload protection
parameters 43.08 and 43.09 according to the application.
•
Set parameter 43.07 Brake chopper run enable to Other [bit] and select from
parameter 10.01 DI status the digital input where the thermal switch of the brake
resistor is wired.
•
Check the resistance value of parameter 43.10 Brake resistance.
•
With these parameter settings, the drive stops by coasting on brake resistor
overtemperature.
WARNING! If the drive is equipped with a brake chopper but the chopper is not
enabled by the parameter setting, the internal thermal protection of the drive
against resistor overheating is not in use. In this case, the brake resistor must be
disconnected.
For settings of other control programs, see the appropriate firmware manual.
