Explanation
Drive control panel
Distributed Drives Communication System; a protocol used in optical fibre
communication inside and between ABB drives.
Electromagnetic Compatibility
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.
Insulated Gate Bipolar Transistor; a voltage-controlled semiconductor type
widely used in inverters due to their easy controllability and high switching
frequency.
Input/Output
Gate driver Power Supply board. An optional board used to implement the
Prevention of Unexpected Start function.
DDCS communication option module
Digital I/O Extension Module
Radio-frequency interference
Main circuit board
Motor control and I/O board. The external I/O control signals are
connected to RMIO.
