    im working on a printing machine and my problem is im failling to adjust my drive so that the speed does not flactuate .originally the machine was supplied with a siemens drive which packed and i had to resplace with a second hand urotherm drive .but now the problem is when you select slow speed the machine runs smoothly ,but as on higher speeds it stars fluctuating (increasing and decreasing ) on its own
