MITSUBISHI inverter FR-D720 series.
Voltage level: three phase 200V.
Frequency converter capacity: 1.5KW.
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 MR-J4-20B1 1 axis servo amplifier.
MITSUBISHI general AC servo amplifier MELSERVO-J4 series.
Rated output: 1.0kw.
Interface: General purpose.
Power supply: three phase AC200V.
Special specification: full closed loop control 4 wire / device end encoder ABZ phase input corresponding support function security unit, support positioning mode MITSUBISHI MR-J4-20B1.
Servo amplifier supporting universal interface.
Servo amplifier for universal interface.
Speed / torque control of position control and analog voltage command can be carried out by using pulse train command.
Support Max instruction pulse frequency 4 Mpulses/s.
2 low frequency vibration can be suppressed at the same time by supporting the seismic algorithm of 3 inertial equipment.
Configurator2 MR to achieve convenient adjustment.
Effectively restrain the low frequency aftershock effect produced by the front end of the boom or the main body of the device 100Hz.
Can effectively shorten the time to control the stability of the aftershock.
In the XY design of trajectory control, improve the accuracy of arc track.
At the same time, it can effectively control the phenomenon of quadrant protrusion caused by the rotation direction of the servo motor, which is caused by friction and twisting. "Universal output function: source type.
Program capacity: 60K step.
Basic operations processing speed: 9.5ns.
Communication interface: USB/Ethernet.
Control mode: stored procedure repeated operation.
Input / output points: 4096 points.
End cap.
CPU built-in functions can be easily set through programming tools.
The built-in I/O function settings can be easily carried out through the parameters of the programming tool.
5 s units can be used for high precision workpiece measurement in pulse measurement mode,
Can be used with a minimum of 5 s units of the input signal of the ON/OFF time (the shortest 200 s) for high precision measurement.
For example, after measuring the ON time of the sensor input,
The "moving speed" and "length" of the workpiecce can be accurrately calculated " MR-J4-20B1.
High precision PWM control of the highest 200kHz.
In the PWM output mode, by setting the ON time and cycle time,
The duty cycle can be changed, and the minimum cycle time is 5 s.
In addition to lighting dimming coonttrol, simple motor control and heater control,
Can also be used to require high resolution detection equipment, such as a wide range of oscillators MR-J4-20B1. "
