Sinking Configuration (pin1 of LTV8441 chip in pin2 of socket U4)
Logic State
JP1 JP2 RP2 (square pin next to RP2 label is 5V)
5V, HAEN (Default configuration) 5V - AECOM1 GND – AECOM2 Dot on R-pack next to RP2 label
5V, LAEN 5V – AECOM1 GND – AECOM2 Dot on R-pack opposite RP2 label
12V, HAEN +12V – AECOM1 GND – AECOM2 Dot on R-pack next to RP2 label
12V, LAEN +12V – AECOM1 GND – AECOM2 Dot on R-pack opposite RP2 label
Isolated 24V, HAEN AEC1 – AECOM1 AEC2 – AECOM2 Dot on R-pack next to RP2 label
Isolated 24V, LAEN AEC1 - AECOM1 AEC2 - AECOM2 Dot on R-pack opposite RP2 label
For 24V isolated enable, tie +24V of external power supply to AEC1 at the D-sub, tie common return to AEC2. Replace RP6 with a 4.7 kΩ
resistor pack. For Axes A-D, AEC1 and AEC2 are located on the EXTERNAL DRIVER (A-D) D-Sub connector. For Axes E-H, AEC1 and AEC2 are
located on the EXTERNAL DRIVER (E-H) D-Sub connector.
Note: AEC1 and AEC2 for axes A-D are NOT connected to AEC1 and AEC2 for axes E-H.
