Main Functions

1. Motor speed & torque regulation
    
   Supports V/F scalar control and sensorless vector control, stable low-speed high-torque output for fans, pumps, conveyors and processing machinery.
2. Integrated braking circuit
    
   Built-in brake chopper, quickly consume motor regenerative energy via external brake resistor for frequent deceleration and emergency stop applications.
3. EMC interference suppression
    
   Onboard Class A filter effectively suppresses conduction interference, meets industrial EMC standards without extra external filter in most cabinet layouts.
4. Safe torque off (STO)
    
   Safe hardware cut-off of motor torque, meets machine safety standards, reduces external safety relay wiring.
5. Complete multi-level protection
    
   Overcurrent, overvoltage, undervoltage, overload, overheating, motor overload, short-circuit, ground fault, phase loss and communication fault detection, with fault codes uploaded to PLC/HMI.
6. Multi-network communication
    
   Cooperate with CU control unit to support PROFIBUS, PROFINET, Modbus TCP for seamless connection to upper PLC automation systems.
7. Energy-saving operation
    
   Built-in sleep mode for pump/fan loads to reduce no-load power consumption and lower operating costs.

Advantages

• Modular split design (power module + control unit) for flexible maintenance and function upgrade
• Built-in Class A filter and brake chopper reduce external auxiliary component costs
• Wide overload capacity adapts to impact loads such as lifting and conveying equipment
• Compact FSD frame size saves cabinet installation space
• Wide temperature range fits harsh factory, water treatment and metallurgical environments
