Introduction to the manual 9 Terms and abbreviations Term / Description abbreviation Automatic voltage regulator Electromagnetic compatibility Motoring mode Motor operation mode in which the motor rotates the load and takes power from the drive DC link (normal operation). Generating mode Motor operation mode in which the motor decelerates (brakes) the load and generates energy back to the drive DC link.
Operation principle and hardware description 11 Operation principle and hardware description Contents of this chapter This chapter contains a description of a common DC system. It also describes the drive features which are relevant in a common DC system.
12 Operation principle and hardware description Operation basics The main circuit of the drive consists of a rectifier, a DC link and an inverter. The rectifier (input bridge) converts the alternating current and voltage to direct current and voltage for the DC link.
Operation principle and hardware description 13 Overview of the common DC system In a common DC system, you connect the DC links of several drives together in order to share their DC link energy storages. In addition to this basic configuration, there is a wide variety of additional choices with which you can affect the performance of the system.
14 Operation principle and hardware description Benefits of the common DC system Benefits of the common DC system: • You can save energy by using the braking energy of one drive in the others - less energy needs to be taken from the AC power line. •...
Operation principle and hardware description 15 Overview diagram of the drive main circuit The overview diagrams below show the main circuits of the drive modules. The differences between the drive modules, in regards of the use of the drives in a common DC system, are the charging circuit and brake chopper designs.

26 Planning – basics Defining the energy absorbing capacity of the common DC link Use formula 1 below to examine if the common DC link capacitors can absorb the surplus energy of the common DC system. If the condition is true, the energy absorbing capacity is sufficient and you do not need a brake chopper and a resistor to handle the surplus energy.
You must acquire and install the brake resistors separately. See the drive hardware manual for ABB brake resistors for each drive. Use can use either the default ABB brake resistors defined for each drive or other resistors that meet the selection criteria.

Requirements for the AC input connection See the drive hardware manual for the electric power network specification of the drive. Supply all drives which you connect to the AC power line from the same transformer.
32 Planning – additional instructions Selecting the fuses There must be fuses both at the AC supply side of the drive and at the DC connection. They protect the cabling and limit the drive damage in case of a short circuit. Selecting the AC input fuses ...
Planning – additional instructions 33 Phase loss protection We recommend that you use phase loss guard in the AC supplies of the drives which you connect to the AC power line. If one AC fuse blows, the semiconductors of the drives can be overloaded and be damaged if you do not have the phase loss protection.
34 Planning – additional instructions DC contactors DC link separation If you connect drives with different type of charging circuits to the AC power line, you must separate their DC link with a DC contactor.
