Solve Common Industrial Challenges
In many production environments, traditional motor control methods may cause problems such as unstable speed, mechanical vibration, high energy consumption, and difficulty matching different working conditions. This inverter series provides practical solutions through adjustable parameters and intelligent control functions.
1. Improve motor response during starting and changing loads through vector control technology.
2. Reduce mechanical resonance risks with two-stage frequency hopping functions.
3. Support multiple control methods including digital setting, analog setting, PID control, PLC operation, and RS485 communication.
Performance Advantages
The working conditions of industrial machinery are often complex, requiring inverter equipment to maintain stable output while handling frequent starts, stops, and speed changes. The LNC860S series is designed with performance-oriented functions to support continuous industrial operation.
Industrial Variable Frequency Inverter Control Equipment provides accurate motor control through open-loop vector control (SVC), closed-loop vector control (FVC), and V/F control modes. According to different application requirements, users can select suitable control strategies to achieve better operating results.
Stable Operation Under Load Changes
For applications requiring strong starting capability, the inverter supports automatic torque boost, with starting torque reaching up to 150% at 0.5Hz. Automatic slip compensation helps maintain more accurate motor speed, especially when load conditions change during operation.
The system also supports short-term operation during momentary power failures, helping reduce production interruptions caused by temporary power fluctuations. Low-noise operation improves equipment working conditions while maintaining smooth motor performance.
Protection Functions For Equipment Safety
Industrial equipment downtime can directly affect production efficiency. Therefore, the inverter integrates multiple protection functions to improve system reliability.
1. Overvoltage protection and overcurrent protection to reduce abnormal operation risks.
2. Overload and overheating protection to support long-term equipment operation.
3. Short-circuit detection, phase-loss protection, undervoltage protection, and other protective functions for safer use.
Flexible Configuration
Different industrial machines have different control requirements. A fixed control method may limit system upgrades, while flexible communication and programming functions allow equipment manufacturers to design more adaptable solutions.
The Industrial Variable Frequency Inverter Control Equipment supports multiple frequency source selection methods, including operation panel settings, analog signals, multi-speed settings, PID control, simple PLC settings, pulse input, and RS485 communication. These functions allow the inverter to adapt to different automation systems without complicated additional control devices.
Built-in PLC And Communication
The built-in PLC function supports up to 16-speed operation, helping simplify control processes in applications requiring multiple working speeds. The standard RS485 communication interface supports Modbus protocol, allowing convenient connection with industrial control systems.
The inverter also provides multiple input and output functions, including digital input terminals, analog input channels, pulse input, relay output, analog output, and high-speed pulse output. These options provide greater flexibility for machine builders and automation engineers.
