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 avail-
able as rotary and linear drives. and are used for machine tools, handling robots,
and packaging machines.
Servoregelung
For –> "Motor"s equipped with a –> "Motor encoder", this control type allows oper-
ation with a high level of –> "Accuracy" and –> "Dynamic response".
In addition to the speed control, a position control can be implemented.
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 Module"s.
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.
PROFIBUS diagnostics, function generator, trace).
See –> "SIZER", –> "Engineering System".
Steuerwort
Bit–coded –> "Process data" word. –> "PROFIdrive" transmits this word at cyclic
intervals to control the drive states.
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.
