Panel bus (control of several units from one control panel)
One control panel (or PC) can be used to control several drives (or inverter units, supply
units etc.) by constructing a panel bus. This is done by daisy-chaining the panel
connections of the drives. Some drives have the necessary (twin) panel connectors in
the control panel holder; those that do not require the installation of an FDPI-02 module
(available separately). For further information, see the hardware description and
FDPI-02 diagnostics and panel interface user’s manual (3AUA0000113618 [English]).
The maximum allowed length of the cable chain is 100 m (328 ft).
1. Connect the panel to one drive using an Ethernet (for example Cat 5e) cable.
• Use Menu - Settings - Edit texts - Drive to give a descriptive name to the drive
• Use parameter 49.01* to assign the drive with a unique node ID number
• Set other parameters in group 49* if necessary
• Use parameter 49.06* to validate any changes.
*The parameter group is 149 with supply (line-side), brake or DC/DC converter
units.
Repeat the above for each drive.
2. With the panel connected to one unit, link the units using Ethernet cables.
3. Switch on the bus termination on the drive that is farthest from the control panel
in the chain.
• With drives that have the panel mounted on the front cover, move the
terminating switch into the outer position.
• With the FDPI-02 module and BCU-02 control unit: move termination switch
S1 on the FDPI-02 module into the TERMINATED position.
• With the FDPI-02 module and UCU-22…24 control unit: move termination
switch S1 on the FDPI-02 module into the OPEN position. Move control panel
connection termination switch XPAN TERM on the UCU-22…24 control unit
to ON position.
Make sure that bus termination is off on all other drives.
4. On the control panel, switch on the panel bus functionality (Options - Select drive
- Panel bus). The drive to be controlled can now be selected from the list under
Options - Select drive.
If a PC is connected to the control panel, the drives on the panel bus are automatically
displayed in the Drive Composer PC tool.
