EASY PROGRAMMING Complex programs can be created without the need for ISO programming knowledge. The input of parameters is facilitated by a series of messages and characters that explain the meaning of the various parameters step by step. The programming of work cycles is done by entering the same parameters of the cycle. The sequence of execution of the various cycles can be quickly and intuitively changed. By the way, in addition to affordable new machines and tested used machines, you can expect even more from us: • Consultation and problem-solving at your location • Organization of machine transport to your facility • Installation, commissioning, and turnkey delivery, and more.
