I upgraded to Ex, AV70S, and Servos a while back. I planned to repurpose my original 3HP Mach4 based system with nema 34 steppers to a second machine but have run out of space. So I’m selling. These were purchased in mid-2020 and are lightly used in a hobby/home shop.
In this post:
GMT 3 HP Spindle (ER20)
Avid Plug and Play Spindle Box with Delta VFD
Spindle Cable suitable for 5x10 machine
Spindle wrenches
Tramming plate
Note: plug was changed to 4 prong locking plug.
Asking $900. Located in Denver metro area. Local pickup preferred, can ship for actual shipping costs.
Could you send me the model # and mfg date for the vfd? I want to download the user manual so I can verify it will work with my setup- Mach3, ESS, G540. The drive has specific requirements for the run signal, CW, CCW and the speed input. I live in Ft. Collins.
Eric,
Thanks for providing the link that took me to just about everything I need. If possible, is there a document that also provides a detailed description/requirements for each terminal on the drive (from the CNC control connector)? The information I’m looking for would be something like, 0-10v, 0-5v, Inverted, TTL, PWM & base frequency, etc. This information will help me ensure that this non-AVID application will work.
I have many years experience with industrial high horsepower drives, mostly Allen-Bradly and Siemens. The terminology is slightly different. I just don’t want to mess anything up.
I’m pretty sure the analog signal is 0-10V but I don’t have any more specifics than the Avid specs.
This spindle was used on an Avid ESS based controller originally, then for a short time on the Ex (centroid) controller until replaced with the AV70S on my setup.
Don’t take my word for it, but I’m pretty sure this will work with your setup. These VFDs all typically run the same, 0-10 volts for signal, a relay to start, output for a fault signal, they’re all reasonably standard.
Eric,
Researching some of the drive information from AVID’s documents, I was able to locate the rest of the information I needed from Delta’s archives. Thank you very much!
I would like to contact the seller privately. Is there a simple way to do that within forum? I thought the DM button provided that but I see everything gets posted. I’m just trying to keep personal information like phone numbers and addresses private.
