MITSUBISHI FR-A842-08660-2-60 Rectifying partial off type frequency converter FR-A842-08660-2-60

Purpose: to operate, monitor, and change the parameters through the network.
Applicable frequency converter: FR-A700, FR-F700, FR-E700. MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 15KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation off the inverter, with the acceleration of the motor to improve the frequency and voltage,
The starting current is limited to 150% below the rated current (according to the different types of aircraft, 125%~200%) FR-A842-08660-2-60 FR-A842-08660-2-60.
Starting with power frequency power supply, the starting current is 6~7 times of the rated current, therefore, the impact on the mechanical and electrical.
The inverter drive can be smoothly start (start time longer) FR-A842-08660-2-60.
The starting current is 1.2~1.5 times of the rated current, and the starting torque is 70%~120% rated torque;
For the inverter with the torque automatic enhancement function, the starting torque is more than 100%, which can start with full load.
MITSUBISHI inverter series: FR-A800 MITSUBISHI FR-A842-08660-2-60.
Voltage level: three phase 400V.
Power: 355kw.
SLD converter rated current: 866A.
Structure and function: the rectification part is off type.
Type: CA.
Substrate coating: have.
To maximize the performance of the motor.
Advanced auto tuning function MITSUBISHI FR-A842-08660-2-60.
The newly developed PM motor auto tuning feature can be used to operate other manufacturers of PM motors (Yong Ci synchronous motors) in the sensorless state.
Not only can drive MITSUBISHI induction motor and PM motor, but also can drive other manufacturers of induction motor and PM motor MITSUBISHI FR-A842-08660-2-60.
This means that you can reduce the cost of inventory and supplies.
If the PM motor is produced by a IPM motor or other company using MM-CF, the starting torque is limited to 50%,
Even after tuning is not simple to use and positioning control of zero speed torque) induction motor and permanent magnet motor can be combined freely. MITSUBISHI inverter series: FR-F840.
Voltage level: three phase 400V.
Power: 55kw.
SLD converter rated current: 116A.
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.
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 ccan drive other companies induction motor and PM motor (permanent magnet synchronous motor) FR-A842-08660-2-60.
Other manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving.
