5.2.1. Direct Encoder Supply
The unit provides an auxiliary encoder supply for each sensor channel
(HTL encoders must be supplied by the encoder supply for the RS422 inputs).
The level of the supply voltage is approximate 2 V below the 18 … 30 VDC power supply
at terminal [X3].
The maximum load of encoder supply is 200 mA each channel (Sensor1 and Sensor2).

Example of a direct encoder supply

In case of a direct encoder supply it is mandatory to supply the encoders with the
auxiliary voltage from the unit.
