Glossary
Servoantrieb
An electric servo drive comprises a motor, a –> "Motor module", a –> "Servo con-
trol" and, in most cases, a speed and position –> "Encoder".
Electric servo drives are normally extremely precise with a high dynamic response.
They are designed for cycle times to less than 100 ms, and often have a short-time
overload capacity, which enables quick acceleration. Servo drives are available as
rotary and linear drives. and are used for machine tools, handling robots, and
packaging machines.
SITOP power
–> "Electronics power supply" component.
Example: 24 V DC
Smart Line Module
Unregulated line infeed/feedback with a diode bridge for the infeed and stall-pro-
tected, line-commutated feedback via –> "IGBT"s.
The smart line module provides the DC link voltage for the –> Motor Modules.
STARTER
STARTER is used to commission and parameterize drive units. This tool can also
be used to execute the diagnostic functions required during servicing (e.g. PROFI-
BUS diagnostics, function generator, trace).
See –> SIZER, –> Engineering System.
Zustandswort
Bit-coded –>"Process data" word. –>"PROFIdrive" transmits this word at cyclic in-
tervals to control the drive states.
The abbreviation "ZSW" must be used in all languages!
Terminal Board
Terminal extension module for plugging into a –> Control Unit.
In –> SINAMICS, for example, terminal board 30 (TB30) is available with analog
and digital I/O terminals.
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
