Automatic Fault Resets; Other Programmable Protection Functions - ABB ACS280 Firmware Manual

Temperature monitoring using Pt100 sensors
1...3 Pt100 sensors can be connected in series to an analog input and an analog
output.
The analog output feeds a constant excitation current of 9.1 mA through the
sensor. The sensor resistance increases as the motor temperature rises, as
does the voltage over the sensor. The temperature measurement function
reads the voltage through the analog input and converts it into degrees Celsius.
It is possible to adjust the motor temperature supervision limits and select how
the drive reacts when overtemperature is detected.
For the wiring of the sensor, see the

Automatic fault resets

The drive can automatically reset itself after overcurrent, overvoltage,
undervoltage and external faults. The user can also specify a fault that is
automatically reset.
By default, automatic resets are off and must be specifically activated by the
user.
WARNING! Before you activate the function, make sure that no dangerous
situations can occur. The function resets the drive automatically and
continues operation after a fault.


External events (parameters
Five different event signals from the process can be connected to selectable
inputs to generate trips and warnings for the driven equipment. When the
signal is lost, an external event (fault, warning, or a mere log entry) is generated.
