7.2 Encoders 

●  Quantification of the angular signal and speed signal (the number of encoder lines and 

their multiplication in the encoder evaluation of the converter for each axes rotation and 

the measuring accuracy of the encoder are crucial here). 

●  Sampling time of the current, speed, and position controller.

Encoders 

Encoder system 

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 supply. Due to the wide range of different 

applications, it is impossible to provide a comprehensive list of suitable encoders. 
Example of absolute phase-angle encoder with EnDat: RCN series (Heidenhain) 
Examples of incremental single-phase encoders (1 V

pp

): RON, ERA, ROD series 

(Heidenhain) 
 

 

NOTICE 

 

We cannot guarantee the composition, nature, state, or quality of non-Siemens products. 

Read the detailed text in "Manufacturer recommendations" in the appendix. 

 

Requirements regarding the encoder  

Your choice of encoder depends on the general application and converter-specific 

conditions. The encoder resolution depends on requirements regarding accuracy and noise 

immunity. Refer also to the documentation for the drive system used. 
 

 

WARNING 

 

Incorrect commutation can result in uncontrolled motor movements. 
When the encoder is replaced, make sure that the commutation setting is correct. The 

procedures involved here must only be carried out by trained personnel.
