Terms and abbreviations
Term/Abbreviation Description
BAMU Voltage/current measurement unit
BCU Type of a control unit
BDCL L-filter. BDCL-14 and BDCL-15 filters are used with DC/DC converters.
BDPS Type of the R8i module internal power supply board
BFPS Type of a power supply and control board for the cooling fan in frame R8i modules.
The BFPS is located in the fan control box below the main cooling fan of the
module.
Control board Circuit board in which the control program runs
Control unit Control board built in a rail-mountable housing
Cubicle One section of a cabinet-installed drive. A cubicle is typically behind a door of its
own.
DC/DC converter DC/DC converter charges or discharges an energy storage (such as a battery or
capacitors) in the DC bus.
DC/DC converter

Drive Frequency converter for controlling AC motors
EMC Electromagnetic compatibility
Energy storage Device that stores electrical energy, for example, a battery or a super capacitor.
Flat-PLS Rittal TS 8 Flat-PLS, a busbar system for standard, commercially available flat bars
Frame (size) Refers to power modules that share a similar mechanical construction, for example:
• DC/DC modules of frame R8i
• frame 2×R8i includes two size R8i DC/DC modules.
To determine the frame size of a component, refer to the rating tables in chapter
Technical data .
IGBT Insulated-gate bipolar transistor
INU See Inverter unit
Inverter Converts direct current and voltage to alternating current and voltage.
Inverter unit Inverter module(s) under control of one control board, and related components. One
inverter unit typically controls one motor.
Multidrive Drive for controlling several motors which are typically coupled to the same
machinery. Includes one supply unit, and one or several inverter units.
Parameter In the control program, user-adjustable operation instruction to the drive, or signal
measured or calculated by the drive
PLC Programmable logic controller
