Tuning a Delta VFD-VE with encoder card (Resolved?)

Delta VFD-VE: I upgraded the old CNC10 control. Machine was working fine.
New Centroid Control.
Have everything nearly done.
What I am having a problem with now, is that Input 12 (Zero Speed Input) is turning on and off after the M19 Spindle Orient is completed.
Spindle is not moving, but as you watch the Actual RPM indicator on CNC12 it is staying zero but I noticed the +/- signs flickering next to the 0. The flickering was corresponding with the flickering Input 12 (Zero Speed Input). I put my fingers on the spindle, while I could not turn it, I could also feel the spindle almost "dithering" as if it were a servo. In fact this might be what it is doing? Since the Orient input to the VFD is active and the spindle looks for the proper position and attempts to hold it there.
In checking the Spindle Analog output while this was occurring, it was rock solid on the motion controller output as well as the Analog input terminals on the VFD.
Reminder, I am running the control and the VFD single phase. This was not a problem with the old DC3IO system and there were no issues with the older control system. The VFD has its encoder card an ENV-PG01L

I wouldn't have thought I would have needed to change a thing on the VFD or "Tune it" since it was working fine with the old Centroid Control.
Working with a VFD with encoder board and "tuning" is new to me.
Thanks in advance for any advice. Current report attached.
