Inserting measuring systems (encoders)
Encoder types
In measuring systems, there is a general distinction between two types of encoders:
• Motor encoder
Motor encoders are normally mounted on the motor shaft so that motor motion (angle of
rotation, rotor position, etc.) can be directly measured. They provide an actual speed value
that is incorporated in the control (speed and current control) so that for fast controllers the
actual speed value must also be provided sufficiently quickly. This is the reason that high
quality encoders must be used for motor encoders.
– Siemens motors that have already been configured are created in the device view with the
– DRIVE-CLiQ motors are inserted together with an encoder. The drive and encoder
• Machine encoder
Machine encoders are installed in the machine. Using machine encoders, for example, you
synchronize the speed of a belt to another belt, or you determine the position of a workpiece.
Basic, mounted encoders can be used in this case as these values are normally not required
in a fast speed controller or current controller cycle.
Available encoders in Startdrive
The following encoder types are supported in Startdrive:
• DRIVE-CLiQ encoder
These encoders are parameterized when downloading - and after an upload, are correctly
displayed.
• SIN/COS encoders
Incremental encoders that supply a sinusoidal/cosinusoidal type signal are also available
with SSI protocol.
• HTL/TTL encoders
Incremental encoders, which supply a square wave pattern, are also available with SSI
protocol.
• Resolvers
Rotary position encoders.
• EnDat 2.1
Absolute encoders, which are controlled via the ENDAT 2.1 protocol.
• SSI encoder
Absolute encoders, which are controlled via the SSI protocol.
• Distance-coded zero marks
Zero marks are set if reference point approach is not possible or is not accepted.

parameters are transferred when you then load the configuration to the drive
(download). The correct motor and encoder configuration are available offline in the
project after an upload.
