Automation solution
The SIMOTION Motion Control system offers, in combination with the SINAMICS S120 drive system and our highly dynamic motors (e.g. the 1FT series), sophisticated complete solutions for electrically driven injection molding machines.
The motor range offered can implement forces in full stroke position of over 8000 kN. Torque motors allow axes with high torques to be directly driven at a low speed, so no mechanical translation by means of belts or gears is required. In combination with the SIGUARD 3TK safety relay, protection against restarting of axes after emergency stop can be cost-effectively implemented in accordance with EN 954 1 Category 3. Corresponding test certificates are available.
Automation solution example for SIMOTION D4x5
Application IMe (Injection Molding Electric) for SIMOTION
- Supports the complete machine control
- Comprises all the technology functions for controlling a fully-electronic injection molding machine with 6 axes: dosing, decompression, injection, injection unit, mold, ejector and mold height adjustment. Implements
- motion control (closed-loop control of position, speed and pressure) of all machine axes as well as
- temperature control
-
Executes on
- Drive-based (SIMOTION D) controls in combination with SINAMICS S120
- PC-based (SIMOTION P)
- Controller-based (SIMOTION C) controls in combination with SIMATIC Panels
- A special machine control panel can be connected over PROFIBUS, if required
- The applicationis supplied with the complete documentation (German and English).
- Prerequisite for using the application IMe for SIMOTION is the software license "Injection molding". This license supports operation of 6 electrical axes and 16 temperature channels.
Machine control
- Structured Text (ST) programming language according to the IEC 61131 3 standard
- Support for different mechanical construction types (e.g. dual-plate locking system or toggle lever locking unit, nozzle unit pressure through motor torque or locked through a motor brake)
- Predefined sequence using the operating modes automatic, semi-automatic, manual for setting up the machine, dry cycle (dry running of the locking unit) or jog mode for single axes
- Freely definable speed profile "Velocity over distance" with optional jerk limitation for smooth traversing of axes during all positioning movements
- Freely definable pressure profile "Pressure over distance" or "Pressure over time"
- Pressure control during the dwell pressure phase
- Mold protection function either via pressure sensor or motor torque
- Kinematics of the toggle lever can be adapted by means of electronic cams or formulas
- Logging (trace) of all important process values (up-to-date speed and pressure curves) for the mold also during dosing and injection
Temperature control
- 16 temperature channels (expandable)
- Self tuning of closed-loop controllers on heating up with self tuning of all controllers in parallel
- Switching of the strip-type heaters with digital, pulse length modulated actuating signal with adjustable minimum on-time
- Operation of heating sections, cooling sections or combined heating and cooling sections
- Operating modes (operating setpoint closed-loop control, reduced setpoint closed-loop control, metering mode, self tuning, etc.)
- Starting function, e.g. for defined drying of hot channels
- Plausibility check and filtering of actual values
- Parameterizable PID or DPID controller with high dynamic response and control quality
