Term/Abbreviation Explanation
CDP312R Drive control panel
DDCS Distributed Drives Communication System; a protocol used in optical fibre
communication inside and between ABB drives.
EMC Electromagnetic Compatibility
Frame (size) Size of the frame into which the drive module is assembled. Several
supply modules with different nominal powers may have the same frame
size. The term refers to modules that have a similar mechanical
construction.
To determine the frame size of a drive module, refer to the rating tables in
chapter Technical data.
IGBT Insulated Gate Bipolar Transistor; a voltage-controlled semiconductor type
widely used in inverters due to their easy controllability and high switching
frequency.
I/O Input/Output
