MITSUBISHI MR-J2-20A

Control axis: maximum 2 axes.
Operation cycle: 0.88ms.
Interpolation function: linear interpolation (maximum 4 axis), 2 axis arc interpolation.
Color signal: 2 points.
Color detecting set: 4 set.
Only need to use the PLC program can easily achieve synchronous control, cam control, speed and torque (push pressure control) and other advanced motion control MR-J2-20A.
Equipped with standard synchronous encoder and color detection function necessary function MR-J2-20A
Can be no procedures for setting. Strong support for MELSOFT.
Can fully apply LD77MH of the old program.
Let motion control more simple. Motor series: low inertia, medium and small capacity.
Using a serial absolute / incremental encoder MR-J2-20A.
Rated output power: 0 . 75kw.
Rated speed: 3000rpm.
With a brake band.
Shaft end: straight shaft.
Comparison of single phase induction motor and servo motor.
The working principle of the AC servo motor is similar to that of the single phase induction motor,
But the rotor resistance of the former is much larger than that of the latter,
So the servo motor is compared with the single machine asynchronous motor,
There are three notable features:
1, large starting torque MR-J2-20A.
2, a wide range of operation.
3, no rotation phenomenon.
AC servo motor running smoothly, low noise.
But the control characteristic is non-linear, and because the rotor resistance is big, the loss is big, the efficiency is low,
Therefore, compared with the same capacity DC servo motor, the volume is large and the weight is heavy,
So it is only suitable for 0.5-100W small power control system. Input and output points: 4096 points.
Input / output data points: 8192 points.
Program capacity: 30K.
Basic command processing speed (LD command) s:0.15.
Integral type: the PLC components are installed together or a few pieces of printed circuit board,
And together with the power supply installed in the casing to form a single overall called the host or the basic unit, small, ultra small PLC using this structure.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance.
Each scanning process. Focus on the input signal sampling. Focus on the output signal to refresh.
Input refresh process. When the input port is closed,
Program in the implementation phase, the input end of a new state, the new state can not be read.
Only when the program is scanned, the new state is read.
A scan cycle is divided into the input sample, the program execution, the output refresh.
The contents of the component image register are changed with the change of the execution of the program.
The length of the scan cycle is determined by the three.
CPU the speed of executing instructions.
Time of instruction.
Instruction count.
Due to the adoption of centralized sampling.
Centralized output mode.
There exist input / output hysteresis phenomena, i.e., the input / output response delayy MR-J2-20A.
User program storage cappacity: it is a measure of how much the user application can store the number of indicators .
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words. PLC to store instructions and data in words.
General lloggical operation instructions each account for 1 words MR-J2-20A. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
