3.5.1.3 No motor encoder, external encoder for positioning 
In some applications the speed control accuracy and the dynamic behaviour of a 
sensorless motor control are sufficient. Positioning is possible in non-slip and in slip-
containing systems via an external encoder. 
Configuration 30 = 440, only position encoder

the application 
Set the encoder behaviour in the correlative parameters for speed sensor 1 and 
speed sensor 2. The speed sensor 1 parameters are only available if an expansion 
module with speed sensor input is installed. 
3.5.1.4 Consider the operation mode settings for speed sen-
sor input 
The digital input signals S4IND, S5IND and S6IND can set as signal sources in all 
configurations (parameter 
Configuration 30). 
− In parameter settings 
Operation Mode 490 > 0 the inputs S4IND and S5IND are 
evaluated only as speed sensor inputs. Other functions at these inputs are not 
evaluated. 
− In parameter settings 
Operation Mode 490 > 1000 additional the input S6IND is 
evaluated as speed sensor track. Other functions at this input are not evaluated.
