Panel Bus (Control Of Several Inverter Units From One Control Panel) - ABB ACS880-104 Hardware Manual

Panel bus (Control of several inverter units from one
control panel)
One control panel (or PC) can be used to control several inverter units by constructing a
panel bus. This is done by daisy-chaining the panel connections of the units. Frame
R1i...R5i modules have the necessary panel connectors in the control panel holder which
is optional for some frame sizes (for details, see chapter
R6i...R8i modules require the mounting of an FDPI-02 module (available separately) on
the control unit. For further information, see FDPI-02 diagnostics and panel interface
user's manual (3AUA0000113618 [English]).
1. Connect the panel to one unit using an Ethernet (eg. CAT5E) cable.
•
Use Menu – Settings – Edit texts – Drive to give a descriptive name to the unit
•
Use parameter 49.01 to assign the unit with a unique node ID number
•
Set other parameters in group 49 if necessary
•
Use parameter 49.06 to validate any changes.
Repeat the above for each unit.
2. With the panel connected to one unit, link the units using Ethernet cables.
3. Switch on the bus termination on the unit that is farthest from the control panel in the
chain. With units that have the panel mounted on the front cover, move the terminating
switch into the outer position. With an FDPI-02 module, move termination switch S2
into the TERMINATED position. Termination should be off on all other units.
4. On the control panel, switch on the panel bus functionality (Options – Select drive –
Panel bus). The unit to be controlled can now be selected from the list under Options –
Select drive.
If a PC is connected to the control panel, the inverters on the panel bus are
automatically displayed in the Drive composer tool.
