Other optional features include the prevention unexpected start-up for the inverters provide safe interlock for the system.Overview the construction A multidrive made several different units (see figure below These sections are called multidrive units and the most important units are: ■ drive units ■ diode supply units ■ supply units ■ thyristor supply units ■ dynamic braking units ■ control units (optional) Drive units Inverters have inbuilt capacitors for smoothing the voltage the busbars.2009 . Several different I/O extension modules for different functions such control, monitoring and measurement purposes are available. Supply unit Drive unit(s) ACU ICU DSU/TSU/ISU 6 Product series 3AFE68248531 REV 20. 12-pulse bridge configuration can be implemented with the unit supplied three- winding transformer with thirty degree phase shift betw een secondary windings.2. The electrical connection to the com busbar fuse protected. Diode supply unit (DSU) A diode supply unit used non-regenerative drive systems convert three-phase voltage to DC voltage. separate pulse encoder inter­ face module also possible. Each inverter has drive control unit (DCU) which contains the RMIO board and optional I/O modules. However, an optional fuse switch with capacitor charging device can selected disconnect the hole drive unit
