Features

 
  • Paperback size
    • A6 size for 0.1K to 0.75K (200V).
  • Improved high functionality
    • Stating torque has been improved to above 200% with general -purpose magnetic flux vector control.
    • The 100% constant torque region for a Mitsubishi standard motor (0.4-1.5kW 4 pole) has been expanded to 6-60Hz with general purpose magnetic flux vector control
    • It is possible to response to rapid load changes with the high response current limiting function
  • Further operational improvements
    • Simple operation is achieved with the minimal number of keys with the covered closed during normal operation.
    • The digital operation panel (option) can be mounted on the surface of the operation panel.
  • Excellent low noise design
    • Low noise is realized with the adaption of high carrier frequency PWM control.
    • The audible noise is gentle with modulation control of the tone for low noise.
