Easy to operate, simple settings.
We have prepared a series of equipment and functions for you to work in any place to meet the life cycle of the product.
Allegedly, the motor power consumption accounted for about half of the total power generated by manufacturing industry consumption.
How to achieve energy efficiency in the plant without affecting the productivity.
Less energy consumption and more output FR-A800 series inverter will help you to have both fish and bear''s paw"
Parameters and frequency settings can be modified in the program.
Inverter control, for example, by the input signal to trigger the operation of the inverter, based on the operation of the inverter
The status of the signal output, as well as the monitor output and so on, can be customized according to the requirements.
The control of each machine can be done separately by the frequency converter, and the control of the dispersion is also carried out.
Through combining with the real-time clock function can realize the automatic operation (in option FR-LU08). "
"Power: 15kw.
Voltage: 200V.
Brake resistor, a kind of ripple resistance, is mainly used in the mechanical system of the inverter to control the speed of the motor,
Help the motor to be converted into heat energy due to the regenerative power of the motor.
Braking unit principle: the brake unit is composed of a high power transistor GTR and its driving circuit FR-A846-00770-2-60.
Its function is to link the discharge current braking resistor capacitor voltage or not in the range of the time consumed and the DC part "overpressure",
Need to add external braking components, in order to speed up the speed of the consumption of renewable energy
FR-A846-00770-2-60 "MITSUBISHI inverter FR-F720 series.
Voltage level: three phase 200V FR-A846-00770-2-60.
Frequency converter capacity: 5.5KW.
When the inverter is running, the starting current and starting torque of the motor are how?
With the operation of 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%).
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 FR-A846-00770-2-60.
The inverter drive can be smoothly start (start time longer).
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-F840.
Voltage level: three phase 400V.
Power: 75kw.
SLD converter rated current: 180A.
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 drrive motor FR-A846-00770-2-60.
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).
Othher manufacturers of induction motors, can also be automatically tuned to achieve the best excitation control, thus expanding the use of energy saving FR-A846-00770-2-60.
