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 sensor
module until the required supply voltage is obtained directly at the encoder system (only for 5 V encoder system power
supply).
Only possible for SSI encoders with 5 V supply.

Note
Current controller clock cycle
For a current controller cycle clock of 31.25 µs, use an SMC20 with Article No. 6SL3055-
0AA00-5BA3.
