  • SJ700D-3 series succeed the SJ700-2 series with the additional and enhanced features.


 1. Dual rating

  • SJ700D can be used for both heavy and normal duty.
  • One-frame-size smaller SJ700D may be applicable for variable torque applications

2. Induction motor & permanent magnetic motor control with one inverter.

  • The SJ700D series inverter can drive both induction motors(IM)and permanent magnetic motors(PM).
    (PM motor control : ordering production)

    3. High starting Torque, Powerful Drive and easy setting

    High starting torque of 200% or greater at 0.3 Hz

    Hitachi original 0Hz Domain sensorless vector control

    Keep 150% * torque at 0Hz speed signal Crane applications require high torque at starting

    1* 150%torque in case 1 frame big inverter capacity of motor

    4. Trip avoidance function

    Over current & voltage suppress function

    Higher internal calculation speed* improve current control performance Over-current suppress and Over-voltage suppress function avoid inverter trip during acceleration and deceleration period.

    5. Programming [EzSQ: Easy Sequence] function

    Inverter control by Built-in Programming function

    Simple sequence operation is realized by downloading to an inverter the program created by programming soft EzSQ.
    It is also possible to automatic speed control according to a load situation like a swift lift function for crane or a conveyor, and to operate.
    Since an external circuit can be simplified, a control board is made small and a cost cut can be aimed at.
    SJ700D can perform 5 tasks independent. Therefore, by separating the duplicated code as loops different tasks, overall execution is faster.

    6. Internal Option

    Built-in EMC Filter

    Cost and space reduction compared with external EMC Filter.
    Reduces electromagnetic noise.
    EN61800-3 2nd-Environment

    Brake circuit up to 22kW
    Cost and Space reduction compared with external Braking Controller

    7. Ease of Maintenance

    Easy-removable construction for maintenance.

    Field replacement of cooling fan(s) and DC bus capacitor can be accomplished in a fraction of the time.
    Cooling fanON/OFF control provides longer life.
    Using Logic terminal move to SJ700/SJ700D Series without wiring change.
    Read SJ300 Parameter by WOP remote operator and write them in to SJ700/SJ700D Series

    8. Long life time components & Life time warning function

    Long life time components

    Design lifetime 10 Years or more Dc bus capacitor & Cooling Fan.
    Cooling Fan ON/OFF control lead more longer life time

    Ambient temperature : Average 40 deg C (no corrosive gasses oil mist or dust) Design lifetime is calculation and out of guaranty.

    Life time warning function.

    Avoid trouble before the malfunction by lifetime Warning signal.
    The monitor of the temperature rise of a Dc bus capacitor, cooling fan degradation degree, a cooling fin, and a motor can be carried out.
    Replace the components before the malfunction.

    9. Easy Operation

    User selection of Parameter functions

    Data comparison function

    A display of only the parameter changed from the default is possible.

    User selected function

    Indication User setting 12 Parameters as U001-U012.

    Basic mode (default)

    Indication Basic Parameter for common used Parameters.

    Other Functions

    • The direct input of function code selection is also attained other than a scroll type allowing for a shorter set up time.
    • Continuously pushing the function key for 3 seconds, causes the display to jump to output frequency monitor (d001) mode from every key.
    • Automatic return to the initial display (b164) :
      Without operating for 10 minutes, the display returns to the initial display automatically. (SJ700D Series)

      10. Network compatibility

      • The port corresponding to RS-485 Modbus-RTU is equipped as standard.
        And the communication speed is available up to 115.2kbps.
      • SJ700/SJ700D Series can communicate with DeviceNet PROFIBUS-DP with communication options.

      DeviceNet is a trade mark of Open DeviceNet Vender Association, Inc.
      PROFIBUS-DP is a registered trade mark of PROFIBUS Nutzer Organization.

      11. Global standards

      • Conformity to global standards. CE, UL, c-UL, C-Tick approvals.
        CE, UL, c-UL, C-Tick
      • Logic input & output Terminal apply sink & source logic.
      • Wide Input power voltage range.
