Switch settings 

The front DIL switches require a few settings depending on the signal levels and the mode of 
indicating the direction on inputs and outputs  

 

4.1.

 

Input characteristics 

You can set the desired input characteristics by switch DIL2, positions 6, 7 and 8 

 

0=OFF 
1=ON

(B) 

(A) 

 

 

 

 

 

Single-ended input: Only signals A, B and Z are 
connected, the inverted inputs /A, /B, /Z remain 
unconnected.  
Acceptable input level: HTL, 10 - 30 V *) 
(PNP only, must switch to +) 

(Z) 

(B) 

(A) 

 

 

 

 

 

Differential input (RS422): with every signal, also the 
corresponding inverted signal must be connected  
(A, /A, B, /B, Z, /Z). 
Acceptable input level of differential signals: 3 – 30 volts  

 

 

Setting of the input format is separately for each of the encoder channels, according to 
above indications (A), (B), (Z) 

 

With RS422 setting, the corresponding input will accept RS422 signals as well as 
differential TTL signals and also 10 - 30 V HTL levels. However, a minimum differential 
voltage of 1 volt is required. 

 

Single-ended signals with standard applications need HTL level (10 - 30 volts) *) 

 

*) Where exceptionally single-ended TTL signals have to be processed (i.e. TTL signals with no inverted 
channels), a special DIL switch hidden behind the front plate provides corresponding setting facilities.  
To access this switch, please slightly lift up the front plate on its bottom side as shown on next page.
