16 Introduction to the manual
Categorization by frame size and option module
Some descriptions, instructions and technical data which concern only certain module
or frame sizes are marked with the size identifier (such as "2×R8i", etc.). The marking
derives from the quantity and basic construction of the converter modules that form
the converter unit. For example, frame size "2×R8i" indicates that the converter unit
consists of two frame size R8i converter modules connected in parallel.
The frame size is marked on the type designation labels. The frame size of each drive
module is also shown in the rating tables.
The instructions and technical data which concern only certain optional selections are
marked with option codes (such as +E205). The options included in the drive can be
identified from the option codes visible on the type designation label.
Use of component designations
Some device names in the manual include the component designation in brackets (for
example, [Q20]). This will help you to identify the components in the circuit diagrams
of the drive.
