DRIVE-CLiQ
Abbreviation of "Drive Component Link with IQ".
Communication system for connecting the different components of a SINAMICS drive
system (e.g. -> "Control Unit", -> "Line Module"s, -> "Motor Module"s, -> "Motor"s, and
speed/position sensors.
The DRIVE-CLiQ hardware is based on the Industrial Ethernet standard with twisted-pair
lines. The DRIVE-CLiQ line provides the transmit and receive signals, as well as the +24 V
power supply.
DRIVE-CLiQ Hub Module Cabinet
The DRIVE-CLiQ Hub Module Cabinet (DMC) is a star coupler for multiplying –> "DRIVE-
CLiQ sockets. The DMC can be clipped onto a rail. The DMC20 is available, for example:
See –> "Hub"
Supply
Input component of a converter system for generating a DC link voltage to supply one or
more -> "Motor module"s, including all the required components (e.g. -> "Line module"s,
fuses, reactors, line filters, and firmware, as well as proportional computing power (if
required) in a -> "Control unit".
External encoder
Position encoder that is not built in or mounted on the –> "Motor", but fitted instead via a
mechanical transmission element or mechanical intermediate element.
The external encoder (see –> "Externally-Mounted Sensor") is used for –> "Direct Position
Detection".
Encoder
An encoder is a measuring system that captures actual values for the speed and/or
angular/position values and makes them available for electronic processing. Depending on
the mechanical construction, encoders can be integrated in the –> "Motor" (–> "Motor
Sensor") or mounted on the external mechanics (– "External Sensor"). Depending on the
type of movement, a distinction is made between rotary sensors ("rotary transducers") and
translatory sensors (e.g. - Linear Sensors). In terms of measured value provision, a
distinction is made between –> "Absolute Sensor"s (code sensors) and –> "Incremental
Sensors"s.
See –> "Incremental Sensor TTL/HTL" –> "Incremental Sensor sin/cos 1 Vpp" –> "Resolver".
Hub
Central connection device in a network with star-shaped topology. A hub distributes
incoming data packages to all connected end devices.
