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
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.

|---|---|---|---|
| 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), 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 channel |

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.
| J1 pin # | Pin name | Electrical function | Hall sensor wiring |
|---|---|---|---|
| Shell | PE | Earth/case | Feedback cable shield |
| 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 |
Pins not listed in the table are left open or used for other functions such as Hall sensor.
