CutTo Length Application
Description
Application: Cutting material whose supply is stopped when the actual cutting takes place.
Application areas: Cutting machines are usually used as sub-functions of major production facilities. Typical applications include cutting of metal sheet parts, cutting and punching of paper or cardboard, production of plastic parts.
Function: The material is supplied via servo drives. The drive system signals the machine controller when the material supply was stopped and the material is to be cut. An integrated registration mark control unit ensures even higher cutting precision for printed material.
Solution
The system was implemented with a Lexium 05 servo drive for positioning and a Lexium 15 servo drive with two programmed motion tasks (start/stop).
Both drives communicate with a Schneider Electric Motion Controller via CANopen and control one BSH servo motor each.
- The Lexium 15 drive operates in velocity mode. The two motion tasks are controlled by means of two start/stop signals.
- The Lexium 05 drive controls the supply speed of the material.
In addition to their compact dimensions, these servo motors offer excellent dynamic characteristics due to their low moment of inertia. The integrated SinCos encoders allow the servo motors to be perfectly tuned to the Lexium 05 servo drives. The drive automatically reads the motor parameters, i.e. additional parameterization by the user is not required.
The operator can monitor and change the production parameters via a Magelis HMI terminal which is connected to the motion controller via Ethernet.
