MITSUBISHI FR-A720-90K TECHNICAL MANUAL

Memory format: EPROM.
Number of steps:
Can use up to 16000 steps.
Battery support: do not.
Method of writing and deleting: write and use ROM to write, use ultraviolet ray to delete. MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 0.1KW.
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 FR-A720-90K FR-A720-90K FR-A720-90K Connecting cable for handheld RH GOT and PLC.
Cable length: 10 meters.
Application: RS-422 connection and RS-232C connection FR-A720-90K . Total input and output points: 48 points.
Input points: 24 points.
Output points: 24 points.
Output type: relay output.
Power supply voltage: AC100-240V.
Input signal voltage: DC24V.
8K capacity of the RAM memory, the maximum can be extended to 16K.
CPU arithmetic processing speed of 0.08 S/ basic instructions.
On the right side of the FX2N series can be connected to the input and output expansion modules and special function modules.
The basic unit is built in the 2 axis independent maximum 20kHz positioning function (transistor output type).
Quick disconnect the terminal block, which adopts excellent maintainability to quickly disconnect the terminal blocks, even if the cable is then replaced by the cable.
Clock function and hour meter function, all of the PLC FX2N has a real-time clock standard.
Continuous scanning function, to define the operation cycle for the application of the continuous scan time.
Input filter adjustment function, you can use the input filter to smooth the input signal (in the basic unit x000 to x017).
Note recording function, Component annotation can be recorded in the program register.
Onlinne program editor, online change the program will not lose the working hours or stop production operation FR-A720-90K TECHNICAL MANUAL.
RUN/STOP switch, running on panel / stop switch easy to operate.
Remote maintenance, remote programming software can monitor, upload or uninstall programs and data via modem communications
Password protection, using a eight digit password to protect your program FR-A720-90K TECHNICAL MANUAL.
