Current drives are FET rated at 80vdc 15amp. Motors are max cont amp 9.6a. Max peak 45a. Do I need to size them for the peak or will a gecko 320 work? I would like to keep the proformace the same as the old drives. The drives are getting tired and fault out often with no motion error. So I was getting ready to convert it to mach3 to use the same controller as my small mill. Any suggestions.
