24 Introduction to the manualTerms and abbreviationsTerm/AbbreviationExplanationBCU Drive control unit. The drive contains two BCU control units. One controls the supply unit,the other controls the inverter unit.As standard, the external I/O control signals are connected to the control unit, or optional I/Oextensions mounted on it.Drive Frequency converter for controlling AC motors.In this manual, the term refers to the ACS880-07XT as a whole.EMC Electromagnetic compatibilityEMI Electromagnetic interferenceEMT Electrical metallic tubingFAIO-01 Optional analog I/O extension moduleFCAN-01 Optional FCAN-01 CANopen adapter moduleFCNA-01 Optional ControlNet™ adapter moduleFDCO-01 Optional DDCS communication module with two pairs of 10 Mbit/s DDCS channelsFDNA-01 Optional DeviceNet™ adapter moduleFECA-01 Optional EtherCAT adapter moduleFEN-01 Optional TTL incremental encoder interface moduleFEN-11 Optional TTL absolute encoder interface moduleFEN-21 Optional resolver interface moduleFEN-31 Optional HTL incremental encoder interface moduleFENA-11 Optional Ethernet adapter module for EtherNet/IP™, Modbus TCP and PROFINET IOprotocolsFENA-21 Optional Ethernet adapter module for EtherNet/IP™, Modbus TCP and PROFINET IOprotocols, 2-portFEPL-01 Optional Ethernet POWERLINK adapter moduleFIO-01 Optional digital I/O extension moduleFIO-11 Optional analog I/O extension moduleFLON-01 Optional LonWorks® adapter moduleFPBA-01 Optional PROFIBUS DP adapter moduleFrame (size) Relates to the construction type of the component in question. For example, several drivetypes with different power ratings may have the same basic construction, and a frame size isused in reference to all those drive types.To determine the frame size of a drive type, see the rating tables in chapter Technical data.FSO-12,FSO-21Optional functional safety modulesIGBT Insulated gate bipolar transistor; a voltage-controlled semiconductor type widely used indrives due to their easy controllability and high switching frequency.I/O Input/OutputPower module Supply module or inverter module.
