Pursuing the Ideal Compact Inverter
Designed for excellent performance and user friendliness
Industry-leading Levels of Performance
High starting torque of 200% or greater achieved
by sensorless vector control
(
when sized for heavy duty
).
Speed regulation at low-speed is greatly improved.
–
Fluctuation is 1/2* compared with the previous model.
–
Trip avoidance functions
Conformity to global standards
Sink / source logic is standard
Wide input power voltage range
Simple positioning control
(when feedback signal is used.)

Integrated auto-tuning function for easy sensorless vector control
realizes high torque suitable for applications requiring it such as crane
hoists, lifts, elevators, etc.
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.
Speed regulation at low speed has been drastically improved to
enhance process stability and precision.
CE, UL, c-UL, c-Tick approvals.
Logic input and output terminal can be congured for sink or source logic.
Input voltage 240V for 200V class and 480V for 400V class as standard.
When simple positioning function is activated, speed control operation or
positioning control operation is selectable via intellient 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.
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.
