Glad you are making progress. A lot of variables involved.

I have 73 set to 100 which is 1/4 of 400 and represents 1/4 of top RPM 24,000 or 6000 RPM. This prevents me from running the spindle below 6000 RPM. Since you currently have the FOR signal jumpered to DCM, your spindle would immediately run at 6000 RPM as soon as you powered on the the VFD. Once you get your FOR Relay installed, you can set 73 back to 6000.

Good luck and don't loose any fingers! - Joe
