MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.75KW.
Vector control variable frequency speed control is the practice of the asynchronous motor in the three-phase coordinate system of the stator current Ia, Ib, Ic, through the three-phase to two-phase transformation,
The alternating current of Ia1Ib1 is equivalent to a two phase stationary coordinate system, and then is rotated by the rotor field oriented,
Equivalent to the DC current Im1, It1 (Im1 equivalent to DC motor excitation current in synchronous rotating coordinate system;
It1 equal to the armature current proportional to the torque, and then imitate the DC motor control method, to obtain the DC motor control,
The control of asynchronous motor is realized through the corresponding inverse coordinate transformation A1SH42P-S1 8 channels.
Platinum thermal resistance (Pt100, JPt100).
Nickel thermal resistance (Ni100).
Shedding detection function.
Conversion speed: 320ms/8 channel.
Inter channel isolation.
40 pin connector.
Most suitable for process control of isolated analog modules.
Temperature data can be collected by connecting thermocouple / thermal resistance.
Products can choose multi-channel (8 channel) input type and channel isolation type.
Customers can choose the most suitable model according to the intended use.
Reduce system downtime recovery time.
With a simple operation, you can back up all the data in the CPU to the memory card.
Through regular backup, can be the latest parameters, procedures, etc. to save the storage card.
In the event of a CPU failure, after the replacement of CPU, can be a simple operation,
Restore the system by using the data storage card in advance.
Therefore, it is not necessary to spend time to manage the backup data, but also can shorten the recovery time of the system shutdown.
Auto backup key data
Save the program and parameter files automatically to the program memory (ROM Flash) without using the backup battery,
To prevent the loss of the program and the parameters due to forgetting to replace the battery.
In addition, the soft component data and other important data can be backed up to the standard ROM,
In order to avoid during the long holiday and other planned downtime,
The data is lost due to battery depletion.
The next time the power is turned on, the backup data will be automatically restored.
