Parameters
Variable quantity within the drive system that the user can read and, in some cases, write.
For –> "SINAMICS", all specifications defined in the –> "PROFIdrive" profile are defined by a
parameter.
See –> "Visualization Parameters" and –> "Adjustable Parameters".
PROFIBUS
Field bus to IEC 61158, Sections 2 to 6.
The abbreviation "DP" is no longer included because PROFIBUS FMS is not standardized
and PROFIBUS PA (for Process Automation) is now part of the "general" –> "PROFIBUS".
Sensor Module
Hardware module for evaluating speed/position encoder signals and providing detected
actual values as numerical values at a -> DRIVE CLiQ Socket".
Three mechanical Sensor Module variants are available:
- SMCxx = Sensor Module Cabinet-Mounted
- SME = Sensor Module Externally Mounted (with a high degree of protection)
Servo Drive
An electric servo drive comprises a motor, a –> "Motor Module", a –> "Servo Control" and, in
most cases, a speed and position –> "Sensor"
Electric servo drives are normally extremely precise and have 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.
Servo Control
For -> "Motor"s equipped with a -> "Motor Encoder", this control type allows operation with a
high level of -> "Accuracy" and -> "Dynamic Response".
In addition to speed control, position control can also be implemented.
SITOP Power
Components for –> "Electronics Power Supply".
Example: 24 V DC
Smart Line Module
Unregulated line infeed/feedback unit with a diode bridge for the infeed and stall-protected,
line-commutated feedback via -> "IGBT"s.
The Smart Line Module supplies the DC link voltage for the -> "Motor Module"s.
Control word
Bit-coded -"Process data" word, transmitted by -> "PROFIdrive" at cyclic intervals to control
the drive states.
IBN CNC: NCK, PLC, drive
