A.4 Glossary
STARTER STARTER none
STARTER assists with the startup and parameterization of the drive units. This tool can also
be used to execute the diagnostic functions required during servicing (e.g. PROFIBUS
diagnostics, function generator, trace).
See –> "SIZER" –> "Engineering System".
Steuerwort Control Word STW
Bit-coded –> "Process data" word. –> "PROFIdrive" transmits this word at cyclic intervals to
control the drive states.
Terminal Board Terminal Board TBxx
Terminal expansion board that can be plugged in to the –> "Control Unit".
In –> "SINAMICS", for example, Terminal Board 30 (TB30) is available with analog and
digital I/O terminals.
Terminal Module Terminal Module TMxx
Terminal expansion board that can be snapped onto the installation rail for installation in a
cabinet unit.
In –> "SINAMICS", 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
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:
Frequency control (–> "Sensorless Vector Control") and speed-torque control with speed
feedback (–> "Encoder").
Zustandswort Status Word ZSW
Bit-coded –> "Process Data" word. –> "PROFIdrive" transmits this word at cyclic intervals to
control the drive states.
