Terminal Module
Terminal extension module for snapping onto the installation rail, for installation in
the control cabinet.
In –> "SINAMICS", for example, the following terminal modules are available:
– TM3x = terminal modules with digital and analog I/O terminals
– TM4x = terminal modules with encoder emulation
Vektorregelung
Vector control (field–oriented control) is a high–performance control type for
induction machines. It is based on an exact model calculation of the motor and two
current components that simulate and accurately control the flux and torque by
means of software algorithms, thereby enabling predefined speeds and torques to
be observed and limited accurately and with a good dynamic response.
Two vector control types exist:
The frequency control (–> "Sensorless vector control") and the speed–torque con-
trol with speed feedback (–> "Encoder").
Zustandswort
Bit–coded –>"Process data" word. –>"PROFIdrive" transmits this word at cyclic
intervals to control the drive states.
The abbreviation "ZSW" must be used in all languages!
