These solutions replace old mechanical transmissions between shafts. An encoder is mounted In the master shaft (main), while in the slave shafts (secondary) the conventional motors are replaced with servomotors driven by a Motion Control system.
With the digital synchronism an electronic ratio is established between shafts in a virtual and flexible form, that can be changed at any time, even when the machine is operating.
The elimination of mechanical transmissions offers a wide range of advantages:
- Avoid printing inaccuracies originated when the gears start wearing off.
- Minimizes stopping time for format changeover.
- Allows increasing the machine speed with total precision and maximum printing quality.
