Machine Control Systems
Reliable industrial control infrastructures with PLC, HMI, servo, sensors, and vision
Approach
Why Is Machine Control Critical?
No matter how strong the mechanical structure of a modern machine is, efficient and consistent production is not possible without a control system. A properly selected and well-programmed control infrastructure directly determines the machine’s speed, precision, safety, and remote traceability.
LEMAC analyzes the customer’s machine or production process and designs the most suitable control architecture. PLC selection, program development, HMI design, servo tuning, and sensor integration are all handled by the same engineering team.
Technologies
Which Control Systems Do We Develop?
PLC Programming
Industrial PLC programming covering Siemens, Mitsubishi, Omron, Beckhoff, and other brands. Process control with Ladder, Structured Text, and Function Block diagrams.
HMI Interface Development
Touch HMI screen design that makes it easy for operators to interact with the machine. Recipe management, alarm screens, production statistics, and maintenance alerts.
Servo and Stepper Motor Drives
Servo motor and drive selection, commissioning, and optimization for precise position, speed, and torque control. Multi-axis coordinated motion profiles.
Sensor and I/O Integration
Integration and signal processing of inductive, capacitive, optical, ultrasonic sensors, encoders, load cells, temperature sensors, and pressure sensors.
Machine Vision
Camera-based product recognition, position detection, size measurement, defect detection, and barcode/QR reading systems. Cognex, Keyence, and OpenCV-based solutions.
Safety Systems
Machine safety infrastructure design with safety PLC, safety gate, light curtain, emergency stop circuits, and category classification.
Remote Monitoring and SCADA
Machine monitoring over the network, OPC-UA / Modbus / MQTT protocol integrations, and plant-wide data collection through a SCADA interface.
Frequency Inverter and Energy Management
Frequency inverter selection and commissioning for motor speed control. Energy consumption monitoring and efficiency optimization.
Let us define the right control architecture for your machine together.
Project Process
How Is a Control System Developed?
Machine and Process Analysis
The machine’s working principle, motion axes, sensor requirements, and operator interaction points are identified. Existing electrical plans are reviewed.
Control Architecture Design
The PLC brand and series, I/O count, HMI size, communication protocols, and safety category are defined. The electrical schematic is prepared.
Software Development
The PLC program (ladder / ST) and HMI screens are developed. They are tested in a simulation environment. Alarm logic, recipe management, and reporting modules are added.
Panel Fabrication and Assembly
The control panel is manufactured specifically for the project, cable connections are completed, and the system is installed on site.
Commissioning and Training
The system is tested on site and parameters are optimized. Training is provided to operators and the maintenance team.
