Lamp Test; Semi-Redundant Drive Control Panel (Drive Backup Control); Figure 8-3 Typical Semi-Redundant Drive Configuration - ABB ACS6000 User Manual

8.4.2.1. Lamp test

The illuminated push buttons on the doors can be tested with the lamp test
function as described in the firmware manual, see "Appendix G - Signal and
parameter table".

8.4.3. Semi-redundant drive control panel (drive backup control)

The semi-redundant drive system applies to single drives with an even number of
inverter units.
A semi-redundant drive system consists of the following features:
– One single-motor drive with double or quadruple inverter units for one
common motor.
– One common control unit for the whole drive system.
– Transfer between full- and half-power is not bumpless.
– Line disconnectors are provided in the inverter units to separate the inverters
from the motor.
Note: The configurations shown here are typical examples. Different
configurations are possible. The optional ISU can be used to split up the drive
lineup in half-power mode by opening the DC link.
