We recently purchased a used piece of equipment and i am trying to modernize the control system, but I'm not very familiar with it. This machine has an odd motor design and I'm trying to configure a PF755 to operate it, but I'm unsure of what parameters i need to change. According to the little documentation I received, the main winding's are of the lotus o-deltoid type. Also, I was told the machine has a lot of sidefumbling before it was decommissioned, could this be a spurving bearing failure or are one of the grammeters out of calibration? Does anyone have a source for EthernetI/P grammeters?
