P0.01 should be set to 1
Are you using a relay to start and stop it?
Mach4 has no feedback from the VFD, so this is likely a Mach4 or controller issue. Is your controller providing the 0-10V signal?When I look at the output in mach 4 diag screen, it appears to be flickering.
The manual implies that J16 is labeled with a V and an I?
