Attachment 450380
So, not quite a drop in replacement, but there was some documentation that came when I asked and it is simple enough. I will attach that here too if anyone finds it useful.
Figuring out the wiring of the existing HSD was harder, but eventually I gathered what was what with some double checking from the HSD manuals (via techno cnc site)
What I don't have is and S3 sensor nor, I think, a breaking resistor. I might be able to use the old resistor (I think that is what it is) from the HSD....but the HSD was 2 pole and the knock off is 4 pole so not sure.
I think I will be ready to hook up tomorrow and see if I can get at least a manual tool change to work which was the problem with the HSD, tool holder is stuck in the machine (ie draw bar is stuck).
Might need to figure out how to bypass the S3 sensor in the controller (syntec) and add appropriate delays, etc. I'm expecting that even though the current set up only seems to recognize the s3 every 1/3 time and happily changes while spinning down the other times.
Then see if the VFD needs replacing due to the 4 pole motor or not. I'm assuming the motor will work but at 1/2 speed with the current setup.
I'll post a video of it spinning when I get that far.
