J105 STMC
All connectors are shown as seen looking into the board.
6-way two part screw-terminal connector (both parts supplied).
NOTE: This is a two-part connector.
The part with screw terminals may be unplugged.
Pin | Function | Connection to RS motor 332-082 |
---|---|---|
1 | Motor ground | Motor PSU ground |
2 | Phase 4 output | Green/white lead |
3 | Phase 3 output | Red/white lead |
4 | Phase 2 output | Green lead |
5 | Phase 1 output | Red lead |
6 | Motor positive supply input |
Motor positive supply input |
The motor white lead should be wired to one end of a resistor, and the black lead to one end of another resistor. The free ends of both resistors should then be connected to the motor positive supply. If the supply is 12V, the resistors should be 6.8 ohms, rated at at least 7 watts. The resistors should be located well away from any temperature-sensitive components and the motor positive supply should not be connected to the computer power supply.
Connector: Berg 50-way IDC.
Seen: Looking into PCB-mounted header.
