The Hitachi WJ200 series comes with an integrated auto-tuning function for easy sensorless vector control that offers high starting torque of 200% or greater, suitable for a variety of applications.
Features of the WJ200:
High starting torque and dramatically improved speed stability with advanced sensorless vector control
New and more effective trip avoidance functions, safe-stop function
Simplified auto-tuning procedure (SLV)
Can be used for heavy and normal duty.
Easy setup and operation via standard integral keypad, optional enhanced keypad or via PC software
Password function to prevent parameters or to hide some of all parameters
Data comparison function: Display parameters changed from default setting
Capable of driving permanent magnet (PMAC) as well as standard induction motors
Dynamic braking transistor in all models
Built in Easy Sequence (EzSQ) PLC-like functionality
Simple position control capability
Basic display: Display most frequently used parameters.
User-changed parameter display: Store automatically and display the parameters changed by the user (Up to 32 sets); can also be used as change history.
Active parameter display: Display those parameters which are enabled.
