Smart Functions

  • User-friendly Keypad
    • Detachable keypad with a plug-in connection.
    • Graphic and text keypad supporting multiple languages.
    • Can monitor 3 signals simultaneously.
    • Parameter backup and copy with internal memory.
    • Optimized setup with the Commissioning Wizard tool.
  • NCDrive (PC-based software tool)
    • Easy pilot operation and maintenance.
    • Supports RS-232, CAN, Ethernet.
    • Features: Setting up and checking parameters, status monitoring, error history, inverter operation.
    • Convenience of managing parameter history.
  • DriveSynch

    DriveSynch is the concept of control system to run standard drives in parallel in order to control large-capacity AC motors or enhance system redundancy. This concept is generally suitable for single or multiple winding motors and can be used to create AC drive of up to 5MW with standard drive components.

    • Easily scalable as a modular system.
    • High output through combining small drives.
    • Better system multiplexing than existing drives as each unit can be driven independently.
    • Easy maintenance and servicing for individual drives.
    • Using the same unit enables fewer spare parts and lower overall costs.
    • No special skills are required to engineer, install, operate, and maintain the drive as it consists of standard modules.
    • Supports multi-winding motor driving that require phase differences between windings.
