For 24V isolated enable, tie +24V of external power supply to AEC2 at the D-sub, tie common return to AEC1. 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.
