4-Q-DC Servo Control LSC 30/2 

5.2 Outputs 

5.2.1 

Auxiliary voltage “+Vaux” and “-Vaux” 

 
Auxiliary voltage for supplying an external potentiometer (50 k

). 

 

+Vaux 

positive auxiliary voltage 

terminal [5] 

 

Output voltage 

+3.9 VDC referenced to Sig_Gnd 

 

Max. output current 

2 mA 

 
 

-Vaux 

negative auxiliary voltage 

terminal [6] 

 

Output voltage 

-3.9 VDC referenced to Sig_Gnd 

 

Max. output current 

2 mA 

 
 

5.2.2 

Encoder supply “+Venc” 

 
Auxiliary voltage for supplying the encoder 

 

+Venc 

Encoder supply voltage 

terminal [16] 

 

Output voltage 

+5.0 VDC referenced to Gnd 

 

Max. output current 

80 mA 

 
 

5.2.3 

Status reading “Ready” 

The readiness or error status can be reported to a higher level control through 
the “Ready signal”. In normal circumstances, i.e. with no errors, the “Open 
Collector” output is switched to Gnd. 
In the event of an error (overheating), the output transistor is blocked.
