Argon J4 connector wiring
 | 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-out
| Pin # | Pin name | Descrpition | AC/BLDC motor connection | Brush DC motor connection |
|---|---|---|---|---|
| 1 | VN | HV DC link negative rail | Do not connect, unless linking multiple drives with VN & VP to share their internal power supplies and braking resistor. | |
| 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!. See Argon user guide/Earthing. | |
¹ In some motors U,V,W phases are called R,S,T instead.
J4 wiring guide
Wiring multiple drives with power supply & braking resistor sharing
Note this drawing does not include wiring to motor (J4), motor brake (J3), feedback device (J1), controller (J5) and AC power input circuity.
 | Using HV DC bus sharing via VP and VN terminals or supplying external DC voltage to them, renders the safe torque off STO1 input unusable because STO1 is based on by cutting the AC supply. In order to preserve STO1 functionality with DC bus sharing, the STO1 signal must be fed simultaneously to all DC bus sharing drives. If an external DC supply is used (no AC input to L & N), then STO1 will not operate. STO1 will also be inoperable if DC voltage is supplied to L & N inputs instead of AC. With DC supply, STO1 ibput must be always powered as the internal relay may damage if STO1 used with DC supply. |
