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 –> "Encoder"
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 infeed/regenerative feedback unit with a diode bridge for the infeed and stall-
protected, line-commutated regenerative feedback via -> "IGBTs".
The Smart Line Module supplies the DC link voltage for the -> "Motor Module"s.
Memory card
An external memory card for non-volatile storage of the drive software and corresponding –>
"Parameter"s. The memory card can be plugged into the –> "Control Unit" from the outside.
Different types of cards can be used depending on the device -> SD Card, MMC Card,
"CompactFlash Card".
Control word
Bit-coded -"Process data" word, transmitted by -> "PROFIdrive" at cyclic intervals to control
the drive states.
CANopen interface
