3.3.6 Sensor (X6)
Additional sensors, both incremental and serial encoders, can be connected.
Check on the applied sensor’s data sheet
If the specified inrush current or the maximum continuous current of the sensor should exceed 145 mA, you 
can connect the sensor supply voltage (V
Sensor
) in parallel to the auxiliary output voltage (V
Aux
).
