At the housing with M4 / 1.8 Nm screw
A controller compares the encoder system supply voltage - sensed via the remote sense cables - with the reference
supply voltage of the encoder system, and a
djusts the supply voltage for the encoder system at the output of the sensor
module until the required supply voltage is obtained directly at the encoder system.
Only possible for SSI encoders with 5 V supply.
