MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 55KW.
When the ring is opened, the frequency converter is provided with a load of the motor when the motor is operated with a load at a given frequency,
The range of the motor speed in the rated slip ratio (1%~5%) changes FR-F740-55K-CHT BASIC Manual FR-F740-55K-CHT Instruction manual.
For the requirements of relatively high precision, even if the load changes are also required to operate at a given speed of the occasion,
Inverter with PG feedback function can be used (selection) FR-F740-55K-CHT
If the given acceleration time is too short, the output frequency of the inverter is far more than the change of the speed (electric angular frequency),
Converter will be due to flow over the current trip, the operation stopped, which is called stall FR-F740-55K-CHT BASIC Manual FR-F740-55K-CHT Instruction manual. For the operation panel (FR-DU08) between the connector and the connecting cable.MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 185kw.
SLD converter rated current: 432A.
Structure and function: Standard model.
Type: CA.
Substrate coating: have.
The motor efficiency is not changed in the previous optimal excitation control,
At the same time, the newly developed advanced optimal excitation control can obtain larger torque at startup FR-F740-55K-CHT BASIC Manual FR-F740-55K-CHT Instruction manual.
No need to adjust the parameters (plus deceleration time or torque, etc.), in a short time to speed up to a certain speed,
Can be carried out to maximize the efficiency of energy-saving drive motor.
The automatic tuning function of the loop constant of the motor is not consistent with the constant of the motor, the motor of other manufacturers, and the length of wiring is too long,
Optimum operating characteristic drive motor.
In the state of the sensor can not only drive the high efficiency and energy saving motor and PM motor (MM-EFS), but also can drive other companies induction motor and PM motor (permanent magnet synchronous motor) FR-F740-55K-CHT BASIC Manual FR-F740-55K-CHT Instruction manual.
Othher manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving FR-F740-55K-CHT BASIC Manual FR-F740-55K-CHT Instruction manual.
