Industry leading performance
High starting torque of 200% or greater achieved using sensorless vector control
(when sized for heavy duty)
Sensorless vector control allows for the realisation of high torque required for applications such as cranes, hoist, lifts etc.
Auto-tuning function makes the implementation of sensorless vector control easy and effective.
WJ200 can be used for both heavy and normal duty. One-frame-size smaller WJ200 can be applicable to certain appli- cations.
Trip avoidance functions
Minimum time deceleration function, over-current suppres- sion and DC bus AVR functions are included as standard. These functions increase the robustness of the product and help to avoid unnecessary tripping. Improved torque limiting/ current limiting function enables a load restriction to protect machinery and equipment. (Example of WJ200-075LF)
Model Name Indication
Simple positioning control
(in combination with a feedback signal)
When simple positioning function is activated, speed control operation or positioning control operation is selectable via intelligent input. While the [SPD] input is ON, the current position counter is held at 0. When [SPD] is OFF, the inverter enters positioning control operation and the position counter is active.
Induction motor & Permanent magnet motor & control with one inverter series
The WJ200 inverter can be used to drive both induction motors (IM) and permanent magnetic motors (PM).
PM motors are energy efficient and make effective use of available space.
*The permanent magnet motor control function is only suitable for variable torque application such as fan and pump
Ease of Use
Easy sequence programming function
Logic operations can be realised within the inverter using Hitachi’s EzSQ software without the need for external relays or a PLC. User programs are compiled using a PC program which are then downloaded to the drive.
Safety stop function
WJ200 conforms to the applicable safety standards and cor- responds to Machinery Directive of Europe. Inverter is shut down via hardware, bypassing the CPU, achieving a reliable safe stop function.
(ISO13849-1 Category 3 / IEC60204-1 Stop Category 0)
The WJ200 inverter has a password function to prevent changing parameters or to hide some or all parameters.
