Argon general pages
Argon user guide
This page lists most common wiring schemes to Argon feedback device ports. See also the main article Argon user guide/Wiring.
The naming conventions of feedback device wires and signals vary between different manufacturers. The most important things to ensure are:
- proper ground and supply wiring
- sensor voltage levels are compatible

Pin-out

J1 connector type is 15 pin female D-Sub and should be mated with 15 pin male D-Sub counterpart. Many of the J1 pins have dual functions. The operating mode of pin is determined by feedback device mode selected from Granity.

J1 wiring guide

Devices with differential signaling may use varying mark-up habits of signal pairs. For example differential signal X (which contains two electrical wires) may be denoted as: X+ and X-, or X and \X or X and X. In this Wiki we mark them X+ and X-.

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), typically called Z+ or I+
  • Index- channel (optional), typically called Z- or I-

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

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- (sometimes denoted as Z-) Index- channel
15 CHC+ Differential input C+ (sometimes denoted as Z+) 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), typically called Z or I channel

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 (Z) channel

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

Hall sensor

Some AC/BLDC/Linear motors are equipped with a Hall sensor which allows faster drive initialization after power-on as phase search can be skipped. Hall sensor is also necessary in the case where motor is not able to move freely in both directions when powered on (i.e. if axis rests at the end of mechanical travel or is vertical axis).

Many Hall sensors have differential outputs (non-inverted and inverted channels, just like differential encoder), however Argon has only single ended Hall sensor inputs which supports both output types (single ended and differential).

It is possible to connect a Hall sensor together with other feedback devices to the same port. In such case supply pins may be shared between multiple FBD's.

1 HALL_W Hall sensor input, phase W Hall sensor W (if differential, then W+ channel)
2 HALL_V Hall sensor input, phase V Hall sensor V (if differential, then V+ channel)
3 HALL_U Hall sensor input, phase U Hall sensor U (if differential, then U+ channel)
9 5V_OUT Encoder supply 5V output Hall sensor supply
10 GND Encoder supply ground Hall sensor ground
