Program features 95
Sine filter support
The control program has a setting that enables the use of sine filters (available
separately from ABB and others).
With an ABB sine filter connected to the output of the drive, bit 1 of
must be switched on. The setting limits the switching and output frequencies
to
• prevent the drive from operating at filter resonance frequencies, and
• protect the filter from overheating.
With a custom sine filter, bit 3 of
must be switched on.
(The setting does not limit the output frequency.) Additional parameters must be set
according to the properties of the filter as listed below.

Router mode for BCU control unit
The BCU control unit of an inverter unit can be set to a “router mode” to allow the
control of locally-connected power units (for example, inverter modules) by another
BCU. Using the router mode and some hardware switching, it is possible to have the
same modules alternate between inverter and, for example, IGBT supply use.
The router mode involves connecting the two BCUs together by their PSL2 channels.
When router mode is active, the channels coming from the other BCU are forwarded
to the local modules.
The diagrams below show how the control of four converter modules can be switched
between two BCUs.
Note:
For an example of how to switch converter modules between inverter and
IGBT supply use, see the
ACS880 IGBT supply control program firmware manual
(3AUA0000131562 [English]).
