Good News! I worked out in the garage late last night, going over and over the parameters, looking for soemthing that would work. I got the spindle to turn at full speed, It was in the parameter 00-02 and 00-05 settings, I was able to utililze the operator key pad to incease and decrease the spindle speed. However, I have taken the Pot out of the equation, still unable to get it to work. I ohm tested the Pot, and it seems to go open on the meter as you increase the Pot dial. I could possibly have a bad potentionmeter, but that still doesnt explain the 10V issue. I may have more than one (1) issue and can easily get the switch replaced, I just picked that up.
And you are correct, the manual isn't clear on indicating output or input. I checked the 24V side and GND again and it checked out OK, so I believe that the GND circuit of the VFD is OK. This VFD is over a year old, and hasn't been utilized that much just to test machine in the conversion. I assume with the cost of VFD not, it isn't worth repairing? I'm sure the 10V supply is created on the main power board, but not totaly sure about that.
I choose the A510 because of the single and 3-phase input, I have since moved the machine from my shop, which had 3-phase to my home garage, single phase. There were very few VFD's that would hook up to single and 3-phase inputs. I talked to Teco before purchasing, they indicated that the A510 was very easy set up.
If I do have to replace, any recommendtations? I guess for now I just utilize the operator key pad.
Thanks,
