Operating Principles and Technical Data

Considerations for Field Implementation

• Correct Component Selection and Sizing: Detailed analysis of system requirements (speed, precision, load, cycle time) is vital for selecting each component (PLC, drive, motor, sensor) with the correct size and capacity. Oversizing leads to unnecessary costs and energy consumption, while undersizing can result in performance degradation and premature failures. Technical datasheets of products offered by Mermak CNC Market should be carefully reviewed, and selections should be made in line with manufacturer recommendations.
• Electrical Noise Management and Grounding: Industrial environments are exposed to high levels of electrical noise (EMI/RFI) originating from motor drives, contactors, and other power electronics devices. This noise can disrupt sensitive sensor signals and communication lines. Proper grounding techniques, the use of shielded cables, separation of signal and power cables, and the application of ferrite filters are critical to minimize these issues. Ground loops should be avoided, and all equipment should be connected to a single reference point.
• Software Architecture and Programming Standards: The PLC program, which is the heart of the automation system, should have a modular, understandable, and easy-to-maintain structure. Programming languages and structural approaches (function blocks, subroutines) compliant with IEC 61131-3 standards should be used. Detailed documentation of the program (comments, variable lists, I/O maps) is indispensable for future revisions and troubleshooting. Appropriate development environments and licenses for PLCs obtained from Mermak CNC Market should be determined in advance.
• Mechanical Integration and Assembly Quality: The physical assembly of automation components is crucial for the long-term and reliable operation of the system. Airflow and cooling systems (fans, air conditioners) inside the panels should prevent components from overheating. Cable trays and organized cabling are important for both aesthetics and ease of maintenance. In vibrating environments, special precautions should be taken to securely fasten components and prevent connections from loosening. IP-rated enclosures provide protection against dust, moisture, and chemicals.
• Compliance with Safety Standards and Risk Assessment: Industrial automation systems must be designed and installed in accordance with international safety standards (e.g., EN ISO 13849, IEC 62061) to ensure operator safety. Safety components such as emergency stop buttons, safety light curtains, door interlocks, and safety relays, available from Mermak CNC Market, should be determined and integrated as a result of a proper risk assessment. Safety PLCs are ideal for managing complex safety logic.
• Ease of Maintenance and Service: System design should consider easy access to components, quick replacement capabilities, and remote diagnostics. Maintenance-intensive items such as connection terminals, fuses, and indicator lights should be easily accessible. A spare parts strategy should be determined in advance, and critical parts should be stocked. Industrial modems or VPN solutions can be integrated for remote access.
• Data Management and Industry 4.0 Integration: Modern automation systems should offer not only control but also data collection and analysis capabilities. Production data (OEE – Overall Equipment Effectiveness, cycle times, fault frequency) can be collected and used for efficiency improvements and predictive maintenance. With Industrial PCs, SCADA software, and communication modules available from Mermak CNC Market, this data can be transferred to the company network or cloud-based platforms. Standards like OPC UA facilitate data exchange between different devices.

Common Problems and Solutions

Industrial automation systems can encounter various problems due to their complex structures. Anticipating these problems and providing quick solutions is essential to minimize production downtime.

• Communication Problems: One of the frequently encountered problems is communication interruptions between different automation components. This can result from incorrect cabling (lack of shielding, loose connections), IP address conflicts, incorrect protocol settings, or electromagnetic interference. Solution: Adhere to cabling standards (e.g., TIA/EIA-568), use shielded cables, and ensure proper grounding. Assign a unique IP address to each device, and match communication parameters (baud rate, parity, data bits) across all devices. Monitor packet loss and delays with network analyzers.
• Sensor/Actuator Failures: Contamination of sensors, mechanical damage, incorrect calibration, or electrical failures of actuators (motors, valves) are common. Solution: Sensors need regular cleaning and calibration. Protective measures should be taken against overloading or mechanical impacts. Electrical connections and power supplies of actuators should be checked, and functional tests should be performed with test equipment if necessary. Faulty components should be quickly replaced with spare parts available from Mermak CNC Market.
• Loss of Precision in Motion Control: Especially in servo or stepper motor-based systems, deviations in positioning accuracy can occur. This can be caused by mechanical backlash, incorrectly tuned PID (Proportional-Integral-Derivative) parameters, encoder failures, or tuning errors in the motor drive. Solution: Mechanical connections (couplings, gearboxes) should be checked, and backlash eliminated. The automatic tuning feature of the motor drive should be used, or PID parameters should be optimized manually. Encoder feedback signals should be checked with an oscilloscope, and faulty encoders replaced.
• PLC Program Errors: Logic errors, timing issues, memory overflow, or incorrect I/O addressing in the PLC program can lead to unexpected machine behavior. Solution: Detailed tests should be performed during the programming phase, and simulation tools should be used. In online monitoring mode, variable values and program flow should be tracked. If necessary, error detection can be done by running the program step-by-step (single step). The PLC’s user manual should be consulted for error messages and diagnostic codes.
• HMI Screen Freezes or Incorrect Data: HMI freezes, display of incorrect data, or unresponsiveness prevents the operator from properly managing the system. This usually results from communication interruptions, bugs in HMI software, power fluctuations, or overloading. Solution: Communication cables and protocol settings between the HMI and PLC should be checked. HMI software and firmware updates should be performed. A stable power supply should be used, and HMI system resources (CPU, memory) should be monitored. If necessary, the HMI should be restarted or reset to factory settings.
• Overheating: Overheating of components (PLC, drive, power supply) inside automation panels leads to performance degradation and reduced lifespan. Insufficient cooling, direct exposure of the panel to sunlight, or overloading of components can cause this situation. Solution: Airflow inside the panel should be optimized, and fans or panel air conditioners should be used. Thermal analyses should be performed to identify hot spots, and component placement should be reviewed. Ensure that component operating temperature limits are adhered to.
• Power Supply Problems: Failures or fluctuations in the power supplies, which are the main feed of the automation system, can cause the entire system to operate unstably or shut down. Voltage drops, overload, short circuits, or signs of aging may be observed. Solution: Input and output voltages of power supplies should be regularly checked with a multimeter. The load current should not exceed the nominal current value of the power supply. If necessary, power supply capacity should be increased, or a redundant power supply system should be installed. High-quality and industrial-standard power supplies should be preferred.
