Ports and connectors
J1 feedback device port
J1 connector type is 15 pin female D-Sub and should be mated with 15 pin male D-Sub counterpart. See connector pinout. For connection examples, see article feedback device examples.
Pin-out
Many of the J1 pins have dual functions. The operating mode of pin is determined by feedback device mode selected from Granity.

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.
 | Dangerous & non-isolated mains potential voltages are present in the connector J4! Keep away from this connector and its wiring when drive has been powered recently. Carefully read the page Power supply safe discharging before operating. |
| 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:
