DC1 Schematic

Post by admin » Thu Aug 24, 2017 2:54 pm

I can imagine just about every build will be something electrically unique, but I have had a few requests for info on the VFD and remote that I made on mine. The schematic is attached as a PDF document. Any questions let me know.

Dan,

Hello, I have been tracking this project for quite a while. I wanted to build this but am having a problem getting the correct files to cut the parts. I emailed you about 1-2 months ago and you provided some files but my shop said they can't cut from those. I also downloaded the files in the download section but, the machine shop told me that they can't cut the pieces from those files also. When they open the file, the pictures are very small and unreadable. They said they use IGES files and STEP files. So, in short I am not sure how to get the correct files they need that I can take to cut the parts. If you have these files and if you would be so kind to send them to me, I would truly appreciate it. I hate to bother you with this. If you can send it to me my email is listed below. Thank you for your time and have a great week.

I have the same vfd and motor you used. One thing im not sure about is the programming for the unit. Do you know the settings for your program for the vfd.

Sorry for the delay in my reply.

I left everything at default programming except:

PD001 = 1 (external terminals)
PD002 = 1 (external terminals)
PD003 = 120.00 Hz (for a 4 pole 1725 RPM motor) or 90.00 Hz for a two pole 3450 RPM motor)
PD005 = 120.00 Hz
PD014 = 5 (acceleration of 5 seconds)
PD015 = 5 (deceleration of 5 seconds)
PD041 = 13 (15 kHz carrier frequency. Reduced audible whine in the motor.)

Changed the settings as you suggested, but the issue I have is that when I apply pressure onto the belt the motor will "stall" and just whine. I have to back off drive and "reset" the motor. Do you know what could be causing this issue.

Sounds very much like the motor is wired for 460 V. Check the wiring is for 230 V. This will be on the motor nameplate or a wiring diagram should be attached to the motor.
