126 Electrical installationPanel bus (Control of several drives from one controlpanel)One control panel (or PC) can be used to control several drives by constructing a panelbus. This is done by daisy-chaining the panel connections of the drives. Some drives havethe necessary panel connectors in the control panel holder. Others, including theACS880-37, require the installation of an FDPI-02 module (available separately). Forfurther information, see FDPI-02 diagnostics and panel interface user’s manual(3AUA0000113618 [English]).1. Connect the panel to one drive using an Ethernet (eg. CAT5E) 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.Repeat the above for each drive.2. Chain the panel and the drives together using Ethernet cables.3. Switch on the bus termination on the drive that is farthest from the control panel in thechain.• With drives that have the panel mounted on the front cover, move the terminatingswitch into the outer position.• With an FDPI-02 module, move termination switch S2 into the TERMINATEDposition.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.5. If a PC is connected to the control panel, the drives on the panel bus are automaticallydisplayed in the Drive composer tool.11 32
