Wiring overview

The minimum wiring for a servo system (after configuration state)

1. Safety earthing to port J4 and preferably to the Argon case
2. 24 VDC wiring to port J3
3. Safe torque off and enable signals to port J2. See how.
4. Motion controller wiring to port J5 or if used over SimpleMotion bus, then port J2
5. Feedback device wiring to port J1
6. Motor connection to port J4
7. AC input power to port J4. Use an external fuse with this input.

Optional wiring

1. AC Power line filter on the wire entering J4
2. Wiring of optional braking resistor to port J4
3. Motor solenoid brake wiring to port J3

Additionally following are required for drive configuration with Granity

1. A cable from SimpleMotion V2 USB adapter to port J2

Ports and connectors

J1 feedback device port

J1 connector. Click to enlarge and see pin numbering.

J1 connector type is 15 pin female D-Sub and should be mated with 15 pin male D-Sub counterpart.

Pin-out

Many of the J1 pins have dual functions. The operating mode of pin is determined by feedback device mode selected from Granity. For connection examples, see article feedback device examples.

J2.1 and J2.2 Simplemotion & E-stop ports

J2.1 and J2.2 are RJ45 type connectors and mates with standard Cat 5 & 6 ethernet cables. Both of these ports are connected pin-to-pin parallel to allow chaining of Argon devices. See also:

• See Argon mating connectors and accessories
• For J2.1/J2.2 pinout, see SimpleMotion V2 port article

J3 24V power and motor brake port

J3 is a 3 pole terminal block type connector used for supplying 24VDC to drive and optionally controlling motor solenoid brake.

Pin #	Pin name	Description	Connection
1	BK	Motor brake output	If motor has a 24V solenoid brake, connect brake between BK and V+
2	V+	24V supply positive input	Connect to 24V PSU +
3	V-	24V supply ground, on J1, J2.x and J5 connectors tied to GND	Connect to 24V PSU -

24VDC typical current consumption is between 0.1 - 0.7ADC depending on how much current is drawn by feedback device and an optional motor brake.

Normally an ethernet type cable is plugged from J2.1 or J2.2 to SimpleMotion V2 USB adapter

J4 power & motor port

J4 is a 10 pole terminal block connector for several functions: earthing, AC power input, motor output, regenerative resistor output and HV DC link sharing.

Pin #	Pin name	Descrpition	AC/BLDC motor connection	Brush DC motor connection
1	VN	HV DC link negative rail	Do not connect
2	BR	Braking resistor output	Optional braking resistor terminals. See Argon braking resistor
3	VP	HV DC link positive rail
4	PE ⏚	Protective earth	Connect to motor PE conductor and motor cable shield
5	U	Motor phase output	Motor U phase ¹	Motor armature+
6	V	Motor phase output	Motor V phase ¹	Motor armature-
7	W	Motor phase output	Motor W phase ¹	No connection
8	L	AC mains supply Line	Connect to AC supply line
9	N	AC mains supply Neutral	Connect to AC supply neutral
10	PE ⏚	Protective earth	Connect to supply protective earth. This connection is always mandatory when any voltage larger than 30 VAC or 42 VDC is supplied to the device!

¹ In some motors U,V,W phases are called R,S,T instead.

J5 Inputs/Outputs

J5 Is a 26 pin IDC connector located on the side of Argon. The connector serves as general purpose I/O including:

• Isolated digital inputs (4 pcs) - used for limit & home switches and clear faults signal
• Isolated digital outputs (4 pcs) - used for status indication
• Differential analog inputs (2 pcs) - used as Analog setpoint
• Differential digital inputs (2 pcs) - used for pulse/direction or second encoder
• 5V and GND output - used for supplying switches or external electronics
