Argon user guide/J1 connector wiring

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
Shell	PE	Earth/case	Cable shield
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.

Hall sensor

Some AC/BLDC/Linear motors are equipped with a Hall sensor which allows faster drive initialization after power-on as hasing a.k.a. 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.
