10 Introduction to the manual
The manual is written for readers worldwide. Both SI and imperial units are shown.
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 item designation in brackets, for example
[Q20], to make it possible to identify the components in the circuit diagrams of the drive.

Description
Auxiliary measurement unit
Type of control unit
Series of L-filters, for example BDCL-14-5
I/O module for controlling cabinet fans
Circuit board in which the control program runs
Control board built in a housing (often rail-mountable)
One section of a cabinet-installed drive. A cubicle is typically behind a door of its own.
Charges or discharges an external energy storage (such as a battery or capacitor
bank) from or into the DC bus
Converter power electronics, related components and DC capacitors enclosed in a
metal frame or enclosure. Intended for cabinet installation.
DC/DC converter module(s) under control of one control board, and related components
DC/DC converter unit
Digital input
Direct-on-line
Frequency converter for controlling AC motors
Device that stores electrical energy, for example, a battery or a super capacitor.
Physical size of the drive or power module
Inverter unit
Converts direct current and voltage to alternating current and voltage.
Inverter module(s) under control of one control board, and related components. One
inverter unit typically controls one motor.
Drive for controlling several motors which are typically coupled to the same machinery.
Includes one supply unit, and one or several inverter units.
In the drive control program, user-adjustable operation instruction to the drive, or signal
measured or calculated by the drive.
In some (for example fieldbus) contexts, a value that can be accessed as an object,
eg, variable, constant, or signal.
Programmable logic controller
Drive for controlling one motor
