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 0x8001:17 "Supply voltage". An operating voltage of 5 VDC is preset. Voltage values of 5 VDC, 12 VDC and 24 VDC can be selected. The setting applies to both channels. Before switching to higher voltages, ensure that both encoders support the voltage range.

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)

Encoder operating voltage (supply voltage) 1:

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".
