Reduced run

A "reduced run" function is available for inverter units consisting of parallel-connected inverter
modules. The function makes it possible to continue operation with limited current even if
one (or more) module is out of service, for example, because of maintenance work. In
principle, reduced run is possible with only one module, but the physical requirements of
operating the motor still apply; for example, the modules remaining in use must be able to
provide the motor with enough magnetizing current.
The wiring accessories needed during the procedure are available from ABB.
Indication
The unit is functioning normally.
Data is transferred between the PC and the unit through the USB
connection of the control panel.
There is an active warning in the unit.
There is an active fault in the unit.
There is a fault that requires the stopping and restarting of the
drive/converter/inverter.
The Bluetooth interface is enabled, in discoverable mode, and
ready for pairing.
Data is being transferred through the Bluetooth interface of the
control panel.
There is an active fault in the unit.
Power supply for the control unit is OK.
Indication
There is an active fault in the module.
The module is ready for use.
XSTO connectors are de-energized.
Supply voltage of the internal circuit boards is OK (> 21 V).
