Note
Siemens provides the Application & Mechatronic Support Direct Motors service
Contact your local Siemens office if you require mechatronic support with the following:
• Mechanical design of the machine
• Closed-loop control technology to be used
• Resolution and measuring accuracy of the encoder
• Optimum integration of the encoder into the mechanical structure.
Siemens will support you with dimensioning, designing and optimizing your machine by
means of measurement-based and computer-based analyses.
You can obtain additional information from your Siemens contacts. You will find the
Internet link on "Technical Support" in the "Introduction".
Encoder system
In the following text, encoder systems stand for angular measuring systems, rotary
encoders, encoders etc.
The encoder system has a range of different functions:
• Actual speed value encoder for closed-loop speed control
• Position encoder for closed-loop position control
• Rotor position encoder (commutation)
The encoder system is not included in the scope of delivery. Due to the wide range of
different applications, it is not possible to provide a comprehensive list of suitable
encoders here. A certain encoder type can be ideal for one application, but essentially
unsuitable for another application.
Preferred encoders are absolute angular encoders with DRIVE-CLiQ, EnDat interface or
incremental angular encoders with 1 V
Requirements regarding the encoder
Your choice of encoder essentially depends on the following application and converter-
specific conditions:
• required maximum speed
• required speed accuracy
• required angular precision and resolution
• pollution level expected
• expected electrical/magnetic interference
• specified ruggedness
• electrical encoder interface
