Overview of Coretec AC Servo Press Systems

Coretec offers a comprehensive range of AC Servo Press systems, including the GS and MS Series, designed for various industrial applications requiring precise force control from 2 to 200 kN. These systems integrate advanced controllers, amplifiers, and software to deliver high performance, reliability, and ease of use.

Product Line-up and Specifications

• Force Range: 2 kN to 200 kN selectable based on application needs.
• Series: GS Series (advanced version of CS Series with stronger motors and no origin sensor), MS Series (high force, high load, absolute specifications, excellent for slow speed operations).
• Stroke Lengths: Available in 100, 200, 250, 350, 400, and 500 mm.
• Speed: Maximum press fitting speed recommended at 30 mm/s; GS and CS models recommended to operate at 75% or less of max speed.
• Load Cell Accuracy: ±1.5% full scale (repeatability ±0.5% FS), positional repeatability ±0.01 mm under specified conditions.
• Controller Models: WPS-SP30 (compact), WPS-SP75 (standard), WPS-MSJ4 (industrial use with Ethernet and fieldbus support).
• Power Supply: DC24V or AC200V options with natural or forced air cooling.
• Emergency Stop: Dedicated input on all controllers for direct emergency stop button connection ensuring safety.

Controller and Software Features

• Data Collection & Analysis: Controllers can save up to 100,000 data points per waveform at 0.25 ms intervals, with up to four waveforms selectable (tool speed, current load factor, load rate, etc.).
• Real-Time and Post-Operation Judgments: Real-time zone and frame judgments to stop operations immediately on deviations; post-operation judgments allow stroke value corrections and comprehensive pass/fail assessments.
• External Device Integration: Two expansion slots for optional circuit boards enable communication with PLCs, Ethernet, fieldbus, and external sensors like load cells and linear encoders.
• Programming: Interactive, easy-to-understand programming with block and label methods; supports program rewriting from PLC and conversion from CPS to WPS style.
• Software Suite: WPS-SP Configurator software supports tool operation, data collection, analysis, and management with multi-language support and extensive help functions.
• Operation Simulator: Allows verification of press operations on PC before actual deployment.

Performance Enhancements and Reliability

• Improved responsiveness with a 0.25 ms program execution cycle.
• Enhanced data storage and IoT readiness with USB memory support for saving numeric/waveform data, program archives, and alarm records.
• High rigidity middle mounting flange structure with internal pull operation capability (except MS200).
• Load cell amplifier with built-in microprocessor for tool ID, linearity correction, and operation history.
• Battery-free non-volatile memory operation for easy transport and maintenance.

Applications and Use Cases

Suitable for a wide range of production processes including press fitting (bearings, bushings, pins), staking, bending, forming, joining, punching, cutting, engraving, clamping, straightening, hot pressing, inspection, ultrasonic and heat welding, endurance testing, and more.

Additional Products and Configurations

• C-Frame, 4-Column, Desktop, Multi-Press, and Multiple-Shaft Synchronized Press configurations available.
• Peripheral electrical equipment and nutrunner systems for high-precision tightening.
• Consultation available for forces exceeding 200 kN.

Key Technical Data Extracted from Tables

• Model weights range from approximately 0.3 kg (GS2) to over 100 kg (MS200 series).
• Max instantaneous forces and applicable forces vary by model, e.g., GS5 at 5 kN max instantaneous force, MS100 up to 200 kN.
• Controller dimensions vary: WPS-SP30 (65×180×242 mm), WPS-SP75 (75×190×242 mm), WPS-MSJ4 (51×110×230 mm).
• Load cell accuracy and positional repeatability ensure high precision in press operations.

Safety and Expandability

• All controllers include emergency stop inputs for direct safety integration.
• Two expansion slots per controller allow flexible addition of communication and control options.
• Supports external load cells and linear encoders for enhanced positional accuracy and measurement capabilities.
