Motorgeber
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 Encoder"s for –> "Direct Position
Sensing" 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
