💡 LS ELECTRIC G100: The New Face of Industrial Control​

LS ELECTRIC America has introduced its new low-voltage variable frequency drive, the G100 General AC Drive, designed for industrial automation systems. This compact drive provides reliable motor control while also boasting impressive safety and electromagnetic compatibility (EMC) features.

🛡️ Integrated Safety and EMC Features​

• Safe Torque Off (STO): Thanks to the integrated STO function, compliant with UL 61800-5-1, motor torque can be safely shut off without disconnecting the main power supply. This provides great convenience during maintenance and emergencies.
  
• Built-in EMC Filter: 400 V models include a C3 EMC filter compliant with EN 61800-3 specifications. This filter reduces electrical noise, helping the system operate more stably.
  
• Durable Design: Designed according to MIL-217PLUS standards, the G100 features special airflow management that protects sensitive electronic components (IGBTs and PCBs) from airborne contaminants.
  

⚙️ Motor Control Performance and Flexibility​

The G100 is suitable for both heavy-duty (extruders, cranes) and normal-duty (centrifugal fans) applications. Key motor control modes include V/F control, slip compensation, and advanced sensorless vector control. The sensorless vector algorithm provides high torque output even at low speeds.

• PID Control: Operational flexibility is enhanced with built-in process PID control.
  
• Kinetic Energy Buffering (KEB): Ensures the system continues to operate during momentary power outages.
  
• Flying Start: Offers the ability to catch rotating loads without tripping.
  
• Programmable Inputs: With P1-P8 digital inputs and the Advanced User Sequence feature operated via DriveView9 software, basic PLC logic can be run on the drive.
  

🛠️ Easy Installation and Mechanical Parameters​

• DIN Rail Mounting: Offers DIN rail mounting capability for units up to 4 kW.
  
• Compact Design: Saves space in electrical panels with a 2 mm side-by-side installation distance.
  
• Wiring Options: A pluggable conduit box is available for protective connections.
  
• User-Friendly Interface: Manual frequency adjustments can be made with a keypad featuring an integrated speed potentiometer.
  
• Fan Life Diagnosis: Triggers a multi-function relay alarm after 50,000 hours of cumulative operation, aiding in preventive maintenance planning.
  

📊 Competitive Advantages​

The G100 directly competes with rivals such as the ABB ACS380 and Schneider Electric Altivar Machine ATV320. With UL 61800-5-1 compliance, an integrated C3 filter, and sensorless vector performance, it meets important functional safety and harmonic suppression criteria. With standard RS485 Modbus communication and industrial Ethernet protocol options, it offers the precise footprint, overload thresholds (150% for 1 minute in heavy-duty mode), and DIN rail optimization required by modern machine builders.
