  • Supports multiple control modes: V/f, sensorless vector control (SVC), and vector control with PG card (VC).
  • Fast response with 0.1s acceleration and deceleration, eliminating dead zones for smooth operation.
  • Features energy-saving functions, sleep mode, and built-in PLC programming for automated control.
  • Capable of tension control, torque mode control, and switching between two motor parameters.
  • Wide input voltage range (380V–480V) with overload capacity up to 150% for 60 seconds.
  • Includes communication options like MODBUS and supports LCD keypad for easy monitoring and setup.
FAQs:
  • What is the overload capacity of this variable frequency drive?
    The drive offers an overload capacity of 150% of the rated current for 60 seconds in general-purpose applications, and 120% for 60 seconds in light-load applications, ensuring reliable performance under varying conditions.
  • How does the VFD handle low-speed torque requirements?
    Using advanced vector control, the VFD delivers high torque at very low frequencies: 180% at 0.5Hz in V/f mode, 180% at 0.25Hz in SVC mode, and 200% at 0Hz in VC mode, making it ideal for heavy-load startup and operation.
  • What communication protocols are supported by this inverter?
    The VFD supports standard MODBUS communication, with CAN OPEN and PROFINET protocols currently in development, facilitating integration into various industrial automation systems.
  • Can this VFD control multiple motors?
    Yes, it supports two groups of motor parameters, allowing seamless switching control between two motors, which is useful in applications requiring backup or alternating motor use.
