AXBB-E to Sunfar E550 VFD Terminal Connections

[JAZZCNC]

For this test I connect as follows:
- VFD 24V to Relay port 8 (coil power)
- AXBB-E Port O3 to Relay port 7 (coil power)
- VFD CM Port to Relay port 1 (COM)
- VFD X1 Port to Relay port 2 (NO)

Ok looking at your post again then think I see the problem. You are taking the 24+ for the relay coil from the VFD rather than the 24V PSU.

Connect the 24V+ from the PSU which powers the AXBB-E rather than from the VFD.
