  1. C2000 for Injection Molding Machine 24th Jan, 2013 John Zuo IABG EMEA

  2. TABLE OF CONTENT • Injection Molding Machine Introduction • Hybrid System based on C2000 • Reference Case • FAQ • Appendix

  3. Injection Molding Machine Introduction • Injection Molding Machine is a machine for manufacturing plastic products by the injection molding process.

  4. Injection Molding Machine Introduction • Traditional Injection Molding Machine System Controller Controller Panel adjust pressure & Flow by controlling valve. Motor is always running by rated frequency, so large cost consumption. Hard to maintain. Less efficiency Oil Cylinder Quantity Control Orientation Control Valve Flow Control Valve Overflow Valve Motor Filter Pump Pressure Control Oil Tank

  5. Injection Molding Machine Introduction • Current Injection Molding Machine System More Expensive More Precision No Solution in Delta Electric System based on Servo Control Total solution for hybrid including drive, PM, Sensor. Precision but expensive & no CE yet. EMEA doesn’t launch it yet. Hybrid System based on Dedicated Drive HES Support driving PM motor with Resolver. Support FPID in PLC inside C2000. Economic & Delta available. C2000 Hybrid System based on Common Drive

  6. Hybrid System based on C2000 • System Structure C2000 Pressure sensor - Pcmd PID + + ASR ACR PMSM - Qcmd PQC (Pressure & Quantity Control) PG

  7. Hybrid System based on C2000 • C2000 Function Analysis • FOCPG for PM motor with Resolver. (The general PM motor for injection molding machine has resolver as encoder since it can cover harsh environment and economic.) • FPID based on PLC built in C2000. (The pressure com. & feed. go to PID control, and quantity command must be as the PID output limitation namely Pr08-05 (PQC). So we must use PLC for realizing the necessary logic.) FOC+PM Pressure Com. ACI (0-10V) Output Limitation Pr. 08-05 PI Pressure Feedback AVI (0-10V) Quantity AUI (-10-10V)

  8. Reference Case • One successful application in Turkey

  9. FAQ How can we adjust to C2000 when the pressure overshoot is too big ? If the pressure overshoot is too big, we must reduce the Kp of PID (08-01), and ASR bandwidth (11-03 11-04 11-05). How can we know how big inverter we should choose for injection molding machine ? The customer should tell us the pressure (bar) and flow (L/min) or Pump Outlet (CC/rev) to us, and the we can calculate the current we need, and we can choose the inverter based on the current. Please go to download Delta VJ English Manual which has the detailed calculation equations.
