So I just received two 400W DYN4 driver and motor sets to convert my SX3 mill from steppers. I connected everything per the manual on the bench to test it out and make sure all the wiring is correct but as soon as I power it on with the motor connected to the driver within 5 seconds the drive goes into a fault and on the program it shows it as Overcurrent. If the motor is not connected to the driver and I turn the driver on it works just fine with no faults.
I connected both sets in all possible pairs to eliminate a potential bad component in either system but I got the same behavior from both sets.
Again, everything is brand new with brand new cables, all ordered from CNC4PC. What am I doing wrong?
I am connecting to single phase 220V. Tomorrow I will try with 120V but I have a feeling that is not my problem. The manual says either a bad encoder cable or an excessive load on the motor. The motors were just sitting on the bench so no load whatsoever. Both encoder cables are brand new.
Any suggestions or ideas?
