The circular blade die cutter is a continually rotating machine that makes products widely used in portable computers, LCDs, backlit LCDs and a variety of other fields.

To work correctly and ensure optimal performance, the roll must be kept at a constant tension, while the axle of the tool must have high synchronisation precision.

Estun Industrial Technology offers a complete solution consisting of a TRIO MC664 controller, a ProNet Plus Ethercat servodrive and an EMJ servomotor.

Use of the EMJ servomotor reduces reluctance torque and torque fluctuation. Servomotors in the EMJ family, assembled with 17 or 20 bit serial encoders and available in different sizes, reach 5000 RPM and support peak torques of up to 3 times the declared torque.

With a power range of 50W ~ 5kW, the ProNET Plus EtherCAT servosystem, with basic EtherCAT (Ethernet Control Automation Technology) connectivity, guarantees high performance in environments with little rigidity.

The shaft on the cutting tool uses a 20-bit encoder with high synchronisation and precision.

The Ethercat local bus offers high speed and performance in real time and guarantees precise synchronisation of position and speed for the single shaft on the blade holder.
