ABB ACS880-07 Series - Parameter settings; Ratings

• If the thermal switch is wired to the DIIL input, an overheating resistor will, by default,
remove the Run enable signal from the drive. See also parameters 20.11 Run enabe
stop mode, 20.12 Run enable 1 source and 95.20 HW options word 1.
• If the thermal switch is wired to another digital input input, set the following parameters.
1.
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.
2.
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.
3.
Set parameter 31.02 External event 1 type to Fault.
4.
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.
5.
Set the resistance value of the resistor to parameter 43.10 Brake resistance.
With these parameter settings, the drive generates a fault and coasts to a stop 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.
