Combination
Combination refers to a combination of components which is formed via a
common DC bus or common mains connection. Components such as mains
choke, mains transformer and mains filter are used in common.
Common DC bus
Voltage source backed up with powerful capacitors to supply drive controllers
with power voltage. "Common" means that the DC bus connections of the in‐
volved devices are interconnected.
Configuration
Configuration describes a specific combination of optional modules to form a
configured control section which is ideally suited for the intended application.
Connection point of equipment grounding conductor
The connection point of the equipment grounding conductor is the connection
point at which the equipment grounding conductor is fixed to the component;
the connection point is identified with the symbol
.
Control panel
A control panel is a unit for operating a device. A control panel has input and
output elements, such as a key panel and a display.
Control section
The control section is a separate component which is plugged into the power
section. The control section processes the signals of the connected compo‐
nents (field bus, encoder system, control panel, etc.). Control sections differ
with regard to their performance, function and configuration.
Converter, frequency converter
Drive controller which generates three-phase alternating voltage with variable
amplitude and frequency from the mains voltage with fixed amplitude and fre‐
quency in order to set the speed of three-phase a.c. motors, for example.
Contains the fundamental stages mains rectifier, DC bus and inverter.
Display
The display is part of the control panel for visual output of information.
Drive controller
Device with which a motor can be operated. Umbrella term for converter or
inverter.
Electric drive system
An electric drive system is the entirety of interconnected hardware, firmware
and software components that have an influence on the sequence of motions
of an installation or machine. The electric drive system consists of, for exam‐
ple, supply units, drive controllers, plug-in control units, motors, encoder sys‐
