Hitachi Industrial Components & Equipment

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

3-phase 200V 0.4kW-55kW
3-phase 400V 0.75kW-400kW


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)

Dual rating

3. High starting Torque, Powerful Drive and easy setting

High starting torque of 200% or greater at 0.3 Hz

High starting Torque, Powerful Drive and easy setting

Hitachi original 0Hz Domain sensorless vector control

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

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

Point4. Internal Option

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.

Point7. Easy Operation

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.

Input voltage 240V for 200V class and 480V for 400V class as standard.

12. Environmental Friendliness

Micro Surge Voltage suppress function

Hitachi original PWM control suppressing Motor terminal voltage less than 2 times of INV\ DC voltage E.Lower than Hitachi motor Max. insulation voltage (1,250V) (during regenerating operation increase the DC bus voltage may over motor max. insulation voltage)

Point10. Environmental Friendliness
