Front connectors

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	Description	Connection
BK	Motor brake output	If motor has a 24V solenoid brake, connect brake between BK and V+
V+	24V supply positive input	Connect to 24V PSU +
V-	24V supply ground	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.

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.

J1 pinout is to be announced later.

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. For J2.x pinout, see SimpleMotion V2 port article.

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 name	Descrpition	AC/BLDC motor connection	Brush DC motor connection
VN	HV DC link negative rail	Do not connect
BR	Braking resistor output	Optional braking resistor first terminal. See Argon braking resistor
VP	HV DC link positive rail	Optional braking resistor first terminal. See Argon braking resistor
PE ⏚	Protective earth	Connect to motor PE conductor and motor cable shield
U	Motor phase output	Motor U phase ¹	Motor armature+
V	Motor phase output	Motor V phase ¹	Motor armature-
W	Motor phase output	Motor W phase ¹	No connection
L	AC mains supply Line	Connect to AC supply line
N	AC mains supply Neutral	Connect to AC supply neutral
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.

Side connectors

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 reference
• Differential digital inputs (2 pcs) - used for pulse/direction or second encoder
• 5V and GND output - used for supplying switches or external electronics

Pin-out

Please see Argon I/O connector electrical interfacing before wiring to this port.

Pin #	Pin name	Electrical	Isolated	Function¹
1	GND	Supply	No²	Ground
2	+5V_OUT	Supply		5V output
3	HSIN1-	High speed digital input		Pulse train, Quadrature or PWM input reference
4	HSIN1+	High speed digital input
5	HSIN2-	High speed digital input		Future use (i.e. secondary feedback device)
6	HSIN2+	High speed digital input
7	ANAIN1-	Analog input		Analog input reference
8	ANAIN1+	Analog input
9	ANAIN2-	Analog input		Future use (i.e. secondary feedback device)
10	ANAIN2+	Analog input
11	GPO1-	Digital output	Yes²	Servo ready status. True when drive is initialized and ready to accept user commands/reference.
12	GPO1+	Digital output
13	GPO2-	Digital output		Follow error warning status. True when following error has reached more than user configured 1/8 of fault limit value.
14	GPO2+	Digital output
15	GPO3-	Digital output		Fault stop status. True when drive is stopped due to fault.
16	GPO3+	Digital output
17	GPO4-	Digital output		Braking status. Set true when drive attempts to brake motor.
18	GPO4+	Digital output
19	GPI1-	Digital input		Home switch input.
20	GPI1+	Digital input
21	GPI2-	Digital input		Positive feed enable input. Used for axis limit switches.
22	GPI2+	Digital input
23	GPI3-	Digital input		Negative feed enable input. Used for axis limit switches.
24	GPI3+	Digital input
25	GPI4-	Digital input		Clear drive faults input. Transition from false to true attempts to reset active faults of drive. If drive is simultaneously in enabled state, motor will start moving immediately.
26	GPI4+	Digital input

¹) This is the default function with stock firmware. Function may be different in future or custom firmware versions.

²) Non-isolated lines are referenced to GND pin / J3 V- terminal. Isolated lines have functional isolation between GND and other isolated +-/- pairs.

J6 Expansion slot

This slot is reserved for Argon add-on card that may be installed inside the drive.

DIP Switches

DIP switches serves as address selector when connecting the drive to SimpleMotion V2 bus or Granity.
