Does anyone have technical expertise with this VFD? I'm having two issues that are kicking my a$$.

First the AIN1 A/D seems to be way off and I'm having a hard time beliving it's this bad. With 10 VDC on AIN1, D2-002 shows 9.58VDC. I'm pretty sure the problem is in the VFD because with the same test setup on AIN2, D2-003 shows 10.00VDC.

Second, I can't get the PID function to control the output frequency. When I program it the way I think it should work the output frequency is 0. No matter how I vary the setting or feedback voltage. The settings I have are : P0-001=0, P0-002=5, P0-045=2, P0-047=2, P0-048=1, P0-049=0, P0-050=0. I think that is all I need to get a simple proportional loop running. I know I have control and feedback voltage because of D2-002 & 003.

Any info or insight would be gratefully appreciated. Thanks
