A line module is a power component that generates the DC link voltage for one
or more –> ”Motor module”s from a three–phase mains voltage. The following
three line module types are used for SINAMICS: –> Basic Line Module, –>
Smart Line Module and –> Active Line Module.
The overall function of an infeed, including the required additional components
such as –> Line Reactor, proportional computing power in a –> Control Unit,
switching devices, etc. is called –> Basic Infeed, –> Smart Infeed, and –> Active
Infeed.
For the electric motors that can be driven by –> SINAMICS, a basic distinction is
made between rotary and linear motors in terms of direction of motion, and be-
tween synchronous and induction motors in terms of electromagnetic operating
principle. For SINAMICS, the motors are connected to a –>Motor Module. See
–> ”Synchronous motor” –> ”Induction motor” –> ”Built–in motor” –> ”Motor
encoder” –> ”External encoder” –> ”Third–party motor”
An –> ”Encoder” (e.g. –> ”Resolver”, –> ”Incremental encoder TTL/HTL” or –>
”Incremental encoder sin/cos 1 Vpp”), which is integrated in or attached to the
motor. The encoder detects the motor speed and, in the case of synchronous
motors, also the rotor position angle (of the commutation angle for the motor
currents). For drives without an additional –> Direct Position Measuring System,
it is also used as a –> Position Encoder for position control. In addition to the
motor encoders, –> External Encoders for –> Direct Position Sensing are avail-
able.
A motor module is a power component (DC–AC inverter) that supplies the
power 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 module”s and –>”Double
motor module”s are available.
Slot for an optional module (e.g. in the –> Control Unit).
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” –>”Adjust-
able parameter”
Field bus to IEC 61158, Sections 2 to 6. The suffix ”DP” is no longer included
because PROFIBUS FMS is not standardized and PROFIBUS PA (for Process
Automation) is now part of the ”general” –> PROFIBUS.
Hardware module for evaluating speed/position encoder signals and providing
detected actual values as numerical values at a –>”DRIVE–CLiQ socket”.
There are 3 mechanical versions of sensor modules:
SMCxx = Sensor Module Cabinet Mounted = Sensor modules for cabinet
mounting
SME = Sensor Module Externally Mounted = Sensor modules with a high
degree of protection for mounting outside the cabinet
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 be implemented.
