10 Introduction to the manual
Categorization by frame size and option code
The frame size identifies information which concerns only a certain frame size of the drive.
The frame size is shown on the type designation label. All frame sizes are listed in the
technical data.
The option code (for example, option +E200) identifies information which concerns only a
certain optional selection. The options included in the drive are listed 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 control unit. Contains control electronics, auxiliary voltage circuitry, etc.
Type of control unit
I/O module for controlling cooling 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.
Frame size designation of the diode supply module
DC circuit between rectifier and inverter
Digital input
Diode rectifier and related components enclosed in a metal frame or enclosure. Inten-
ded for cabinet installation.
Diode supply modules under control of one control board, and related components.
Frequency converter for controlling AC motors
Diode supply unit
Physical size of the drive or power module
Incoming unit
DC circuit between rectifier and inverter
Inverter unit
Inverter bridge, related components and drive DC link capacitors enclosed in a metal
frame or enclosure. Intended for cabinet installation.
Inverter module(s) under control of one control unit, 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.
Converts alternating current and voltage to direct current and voltage
Drive for controlling one motor
