Status input
The “Status Input” input is internally connected to 5 V via a pull-up resistor. The encoder fault signal output must actively pull the signal against GND.
External power supply is not recommended. If an external supply is used, the maximum permitted voltage is 5 V against GND.

EL5112 - Connection 2:

Setting the encoder supply via index 0x8001:17

The encoder supply is set centrally for both channels via the index 0x8001:17 (channel 1). The corresponding index 0x8011:17 of the second channel has no parameterization function.

Notice

Setting the encoder supply voltage

  • Before switching to a higher voltage, make sure that the connected encoders support the selected voltage range!
  • To write to 0x80n1:17 "Supply voltage" you have to set the value 0x72657375 (ASCII: "user") in index 0xF008 "Code word".
