A controller compares the encoder system supply voltage - sensed via the Remote Sense cables - with the reference
1)
supply voltage of the encoder system, and adjusts the supply voltage for the encoder system at the output of the drive
module until the required supply voltage is obtained directly at the encoder system (only for 5 V encoder system power
supply). Remote Sense only to X520.
See the diagram "Maximum cable lengths depending on the SSI baud rate for SSI encoders"
