Motor Module
A motor module is a power unit (DC-AC inverter) that provides the power supply
for the connected motor(s).
Power is supplied through the –> DC Link of the –> Drive Unit.
A motor module must be connected to a > "Control unit" via a –> "DRIVE-CLiQ".
The open-loop and closed-loop control functions of the motor module are stored in
the control unit.
–> Single Motor Modules and –> Double Motor Modules are available.
Option Board
PC board inserted in the –> "Control unit" (e. g. a –> "Terminal board" 30, TB30).
Option Slot
Slot for an optional module (e.g. in the –> Control Unit).
Parameter
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 parameter" –> "Adjustable parameter"
PROFIBUS
Field bus to IEC 61158, Sections 2 to 6.
The abbreviation "DP" is no longer included because PROFIBUS FMS is not stan-
dardized 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 de-
tected actual values as numerical values at a –> "DRIVE-CLiQ socket".
Three mechanical sensor module variants are available:
– SMCxx = Cabinet-mounted sensor module = sensor module for snap-on mount-
ing in the control cabinet.
– SME = Sensor module externally mounted = sensor module with high degree of
protection for installation outside the cabinet unit
– SMI = Sensor module internal = sensor module integrated in the motor flange
outlet
Servoregelung
For –> "Motor"s equipped with a –> "Motor encoder", this control type allows op-
eration with a high level of –> "Accuracy" and –> "Dynamic response".
In addition to the speed control, a position control can be implemented.
