Encoder operating voltage (supply voltage)

The encoder supply is generated internally from the 24 V of the power contacts. The encoder supply can be set in index 0x80n1:17 "Supply voltage". An operating voltage of 5 VDC is preset. Voltage values of 5 VDC, 12 VDC and 24 VDC can be selected. The settings are made separately for each channel.

The following tolerances apply

Voltage range

Tolerance

5 VDC

+/- 5% (4.75 V … 5.25 V)

12 VDC

+/- 10% (10.8 V … 13.2 V)

24 VDC

-15% to +20% (20.4 V … 28.8 V)

Notice

Setting the encoder supply voltage

  • Before switching to a higher voltage, make sure that the connected encoder supports 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".
