Selection Recommendations

Regional Adaptation Priority

Europe/North America (high-end manufacturing): Prioritize "Cabinet-Mounted Centralized + Regenerative Feedback Configuration" to meet energy efficiency regulations and multi-axis synchronization needs.

Southeast Asia/Latin America (SMEs): Prioritize "Single-Axis Drive + Distributed Configuration" to balance cost and installation convenience.

Middle East/Africa (harsh environments): Prioritize "Distributed + Explosion-Proof Configuration" to adapt to high temperature, dust, and explosion-proof requirements.

Cost vs. Efficiency Balance

Multi-axis scenarios (≥8 axes): Centralized configuration is more energy-efficient (bus energy sharing) with lower long-term operating costs.

Single-machine/decentralized loads: Distributed configuration has lower installation costs and more flexible future expansion.

Frequently Asked Questions

Installation & Environment

High salt spray in Southeast Asian ports causes frequent tripping after installation -- how to resolve?

Select IP54+ protection modules, add dustproof and moisture-proof covers with forced cooling. Separate power and control cables, ground the shield at one end, and ensure ground resistance < 4Ω. Regularly clean cooling air ducts and filters to prevent overheating protection triggered by poor heat dissipation due to corrosion.

Extreme high temperatures in Middle Eastern deserts lead to frequent overheating shutdowns -- what solutions are available?

Prioritize water-cooled models. For air-cooled models, increase cooling clearance, add independent air ducts and temperature-controlled fans. Place cabinets in shaded areas to avoid direct sunlight. Adjust overload thresholds and derating curves, and operate at reduced loads during high-temperature periods to prevent long-term overheating under heavy loads.

What happens if mixing 480V (North American grid) and 400V (European grid) modules?

It will trigger overvoltage/undervoltage protection or even damage modules. Select line modules and power modules based on the target region's grid: 480V systems require matching line and power modules with corresponding rated voltages. Install input reactors and filters to suppress grid fluctuations and harmonics, complying with local grid standards.

How to install compliantly in explosive areas (e.g., Middle Eastern chemical plants)?

Use ATEX/IECEx certified modules, install drives in safe areas, and use explosion-proof motors and sensors on-site. Adopt sealed heat dissipation design to prevent dust and corrosive gases from entering modules. Wire in accordance with explosion-proof standards, use explosion-proof junction boxes and cable glands, and conduct regular explosion-proof inspections and maintenance.

Commissioning & Communication

Insufficient synchronization accuracy for multi-axis common DC bus in overseas automotive welding lines -- how to adjust?

Adopt CU320-2 + common DC bus configuration and enable PROFINET IRT communication. Configure electronic cam/electronic gear, optimize position loop and speed loop parameters to reduce dynamic response time. Check encoder wiring and shielding to ensure stable feedback signals. Commission single axes first, then connect them online, gradually increasing load and speed to verify synchronization accuracy.

Frequent disconnections or address conflicts with PROFINET communication in overseas machine tools -- what to do?

Check network topology: set terminal resistors to ON at both ends and OFF at intermediate nodes. Avoid duplicate IP addresses/device names and divide independent network segments. Use shielded twisted-pair cables and maintain sufficient distance from power cables. Upgrade firmware to a compatible version, optimize communication cycle and reconnection mechanism to reduce disconnection probability.

Excessive regenerative energy in port gantry cranes causes DC bus overvoltage tripping -- how to solve?

Use regenerative line modules to feed back regenerative energy to the grid. Equip brake units and brake resistors, calculate required resistance value and power to ensure timely energy release. Adjust deceleration time to avoid sudden energy surge during emergency stops. Install DC bus reactors to stabilize bus voltage and prevent overvoltage protection triggering.

Operation & Maintenance

Ground fault (F30021) reported on overseas sites -- how to quickly locate the issue?

After powering off, check if motor windings and cable insulation are damaged or grounded. Inspect if internal drive modules are damaged. Verify the reliability of the grounding system for loose connections or excessive ground resistance. Conduct single-machine operation tests to rule out external load grounding issues; replace motors or cables if necessary.

Slow overseas after-sales response -- how to quickly resume production after module failure?

Stock core spare parts (CU, Power Module, Fan, Brake Resistor) in advance. Establish a remote operation and maintenance system for remote diagnosis and commissioning via gateways like eWON. Train local maintenance personnel and provide Chinese/English commissioning manuals and fault troubleshooting procedures to reduce reliance on overseas after-sales.

Speed fluctuations caused by encoder signal interference in overseas machine tool sites -- how to handle?

Use twisted-pair shielded cables, ground the shield at one end, separate from power cables, and avoid parallel routing. Check if encoder supply voltage is stable and free of ripple. Adjust speed feedback filter parameters and extend fault delay time to reduce false alarms caused by interference. Replace with encoders with stronger anti-interference capabilities if necessary.
