Product Perfomance:


1. High starting torque of 200% or greater achieved by sensorless vector control (when sized for heavy duty).


Integrated auto-tuning function for easy sensorless vector control realizes high torque suitable for applications requiring it such as crane hoists, lifts, elevators, etc.



2. Speed regulation at low-speed is greatly improved.
– Fluctuation is 1/2compared with the previous model. –


Speed regulation at low speed has been improved to enhance process stability and precision.



3. Induction motor & Permanent magnetic motor* control with one inverter


The WJ200 inverter can drive both induction motors (IM) and permanent magnetic motors (PM). Energy conservation and miniaturization can be achieved using PM motors. Moreover, one inverter used for two types of motor.



4. Trip avoidance functions


Minimum time deceleration function, over-current suppress function and DC bus AVR function are incorporated. The functions reduce nuisance tripping. Improved torque limiting/current limiting function enables a load limit to protect machine and equipment.




Ease of Uses:



1. Easy sequence [EzSQ] programming function


Sequence operation is realized by downloading to an inverter a program created with Hitachi's EzSQ software. User program can be compiled on EzSQ software on a PC. External components can be simplified or eliminated, resulting in cost-savings.


EzSQ Example:Energy cost saving by speed reduction.

  • Daytime: Motor speed is automatically reduced to reduce demand during peak hours.

  • Nighttime: Motor speed is increased to take a advantage of off-peak power rates.



2. Safe stop function


WJ200 conforms to the applicable safety standards and corresponds to Machinery Directive of Europe. Shuts down the inverter by hardware, bypassing the CPU, to achieve reliable safe stop function. The safety standard can be met at a low cost.

(Cat.3, PLd to EN/ISO 13849-1 and SIL CL2 to EN 62061/ IEC 61508/ EN 61800-5-2)
* 1-phase 100V class is not certified.



3. Network compatibility & External ports


A serial RS-485 Modbus/RTU port is standard. The WJ200 can communicate via DeviceNet, CompoNet, PROFIBUS and CANopen with optional expansion card (planned). USB (Mini-B connector) port and RS-422 (RJ45 connector) port are standard.



4. Ease of wiring


Screw-less terminals (control circuit terminals) spring-loaded, for use with solid or stranded wire with ferrules.



5. Side-by-side installation


Inverters can be installed with no space between them to save space in the panel.



6. Easy adjustment of frequency


Pot for frequency adjustment is available as option kit.



7. Global standards

CE, UL, c-UL, RCM approvals.
(1-phase 100V class is for UL and c-UL only.)


Logic input and output terminal can be configured for sink or source logic. Input voltage 240V for 200V class and 480V for 400V class as standard.




Ease of Maintanence



1. Long life time components (Design life time 10 years or more)


Design lifetime 10 Years or more for DC bus capacitors and cooling fan.
Cooling fan ON / OFF control function for longer fan life.

Ambient temperature: Average 40ºC (no corrosive gases, oil mist or dust)
Design lifetime is calculated, and not guaranteed.



2. Easy-removable cooling fan


The cooler fan can be exchanged without special tools.



3. Life time warning function


WJ200 diagnoses lifetime of DC bus capacitors and cooling fan(s).

*1 The protection method conforms to JIS C 0920(IEC60529).

*2 The applicable motor refers to Hitachi standard 3-phase motor (4p). When using other motors, care must be taken to prevent the rated motor current (50/60Hz) from exceeding the rated output current of the inverter.

*3 The output voltage decreases as the main supply voltage decreases (except when using the AVR function). In any case, the output voltage cannot exceed the input power supply voltage.

*4 To operate the motor beyond 50/60Hz, consult the motor manufacturer for the maximum allowable rotation speed.

*5 The braking torque via capacitive feedback is the average deceleration torque at the shortest deceleration (stopping from 50/60Hz as indicated). It is not continuous regenerative braking torque. The average deceleration torque varies with motor loss. This value decreases when operating beyond 50Hz. If a large regenerative torque is required, the optional regenerative braking unit and a resistor should be used.

*6 The frequency command is the maximum frequency at 9.8V for input voltage 0 to 10VDC, or at 19.6mA for input current 4 to 20mA. If this characteristic is not satisfactory for your application, contact your Hitachi representative.

*7 The storage temperature refers to the short-term temperature during transportation.

*8 Conforms to the test method specified in JIS C 60068-2-6:2010(IEC 60068-2-6:2007). For the model types excluded in the standard specifications, contact your Hitachi sales representative 

*9 1-phase 100V class is only with CT.
