Application of EP5 in automatic paper cutting machine

1、 Application Introduction
Fully automatic paper cutting machine, mainly used in the cutting process of fixed length paper.
The material currently being cut is the insulation paper material between the stator frame of the servo motor. The servo motor needs to be quickly positioned according to the length (unit: mm) set on the HMI, and then cut off by triggering the cylinder action through the PLC.
The entire section is divided into two workstations, A and B, with two sets of servos that can work independently. The length, speed, and acceleration/deceleration can be set according to the insulation paper of different processes.

2、 Process requirements
1. Both independent workstations can be started separately, and the required paper cutting size can be selected to meet the changes in different stator insulation paper processes
2. High speed start stop, precise positioning error within plus or minus 10 threads

3、 System solution
1. The control system adopts Mitsubishi FX-3GA series PLC+EP5-TL04P servo drive (compatible with 60GSL01330 servo motor)
2. The electrical control box requires a compact layout and a beautiful appearance of the equipment

4、 Advantages of the plan
1. The EP5 series servo drive has a compact structure and easy installation, which can save the volume space of the control box
2. Improved control algorithm, coupled with a 23 bit encoder, effectively improves control accuracy
3. Support remote firmware upgrade for easy maintenance in the future
