MITSUBISHI MR-J4-70B-RJ010 Market price | MR-J4-70B-RJ010 Introduction

Power: 15kw.
Voltage: 400V.
The power factor of the input power factor is up to 0.99 and above (100% load).
Can be connected to multiple inverters, to achieve a common DC bus mode.
Equipped with standard power retrogradation function. Can be isolated from the output of the programmable controller, the a/b/c contact relay, SSR, Tr output.MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V MR-J4-70B-RJ010
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. Analog input channel number: 4CH.

Voltage input
The analog input voltage: DC - 10 - 10V.
Digital output value: 32000 ~ 32000.
Current input
Analog input current: DC0 ~ 20mA.
Digital output value: 0 ~ 32000.
16 bit high resolution (1/32000).
No program can perform scaling and conversion operations.
The most suitable for the requirements of speed and accuracy of the detection equipment.
Easy to filter high frequency interference.
Execute event driven programs via alarm output.
Through the engineering software, the output of arbitrary analog waveform data.
Channel insulation.
Similar to the input and output modules, analog quantity module is the interface between the sensor and the programmable controller.
The difference between the input and output modules is that it is dealing with analog voltage and current signals rather than ON/OFF signals.
The analog module MELSEC iQ-R series is equipped with high-speed conversion (80 s/CH), high resolution (1/32000), channel insulation, abnormal signal detection and other convenient features,
Can achieve high precision analog control.
