This page lists most common wiring schemes to Argon feedback device ports. For connector pin-outs, see the main article Argon user guide/Wiring.

Incremental encoder

Differential

Differential outputs (RS422 electrical standard) of encoder provides a good EMI immunity and supports long cables with high speed signals. Typical differential encoder has 6-8 wires:

  • Ground
  • Supply
  • Channel A+
  • Channel A-
  • Channel B+
  • Channel B-
  • Index+ channel (optional)
  • Index- channel (optional)

The negative outputs have the inverted (or mirror image) signal of the positive outputs.

J1 pin # Pin name Pin function Encoder wire
Shell PE Earth/case Cable shield
5 CHB- Differential input B- Channel B-
6 CHB+ Differential input B+ Channel B+
7 CHA- Differential input A- Channel A-
8 CHA+ Differential input A+ Channel A+
9 5V_OUT Encoder supply 5V output Encoder supply
10 GND Encoder supply ground Encoder ground
14 CHC- Differential input C- Index- channel
15 CHC+ Differential input C+ Index- channel

Pins not listed in the table are left open or used for other functions such as Hall sensor.

Single ended

Single ended output type is usually one of the following:

  • Open collector outputs
  • TTL outputs
  • CMOS outputs

Typical single ended encoder has 4-5 wires:

  • Ground
  • Supply
  • Channel A
  • Channel B
  • Index channel (optional)
J1 pin # Pin name Pin function Encoder wire

6 CHB+ Differential input B+ Channel B
8 CHA+ Differential input A+ Channel A
9 5V_OUT Encoder supply 5V output Encoder supply
10 GND Encoder supply ground Encoder ground
15 CHC+ Differential input C+ Index channel

Pins not listed in the table are left open or used for other functions such as Hall sensor.

Pin-out

Many of the J1 pins have dual functions. The operating mode of pin is determined by feedback device mode selected from Granity.
