Electrical installation 119Controlling several drives through panel busOne control panel (or PC) can be used to control several drives by constructing apanel bus.1. Connect the panel to one drive using an Ethernet (eg. CAT5E) cable.Note for IP55 (UL Type 12) drives: Remove the front cover and put the cablesthrough the control cable lead-throughs.• Use Menu – Settings – Edit texts – Drive to give a descriptive name to thedrive.• 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. With the panel connected to one drive, link the drives together using Ethernetcables. (Each panel platform has two connectors.)3. In the last drive, switch bus termination on. With a panel platform, move theterminating switch into the outer position.Termination should be off on all otherunits.4. On the control panel, switch on the panel bus functionality (Options – Selectdrive – Panel bus). The unit to be controlled can now be selected from the listunder Options – Select drive.5. If a PC is connected to the control panel, the drives on the panel bus areautomatically displayed in the Drive composer tool.6. For IP55 (UL Type 12) drives, Install the front cover.
