Input and output points: 1024 points.
Input / output data points: 1024 points.
Program capacity: 14K.
Basic command processing speed (LD command) s:1.0.
Coaxial data communication line function.
User program storage capacity: it is a measure of how much the user application can store the number of indicators MR-J4-20B-RJ.
Usually in words or K words as units. 16 bit binary number is a word,
Every 1024 words are 1K words MR-J4-20B-RJ PLC to store instructions and data in words.
General logical operation instructions each account for 1 words. Timer / counter,
Shift instruction accounted for 2 words. Data operation instructions for 2~4.
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 MR-J4-20B-RJ.
Modular: PLC is the basic components of a separate module.
Medium and large PLC used this way. Easy maintenance. Motor series: ultra low inertia, small capacity MR-J4-20B-RJ.
Using a serial absolute / incremental encoder.
Rated output power: 0 . 1kw.
Rated speed: 3000rpm.
With the brake with brake.
Without GB.
Shaft end: straight shaft.
The rotor of the servo motor is a permanent magnet, and the control of the servo amplifier is controlled by the U/V/W three-phase electric electromagnetic field,
The rotor rotates under the action of the magnetic field, and the encoder feedback signal of the motor is given to the driver,
According to the feedback value and the target value, the driver is compared,
Adjust the rotor rotation angle.
The accuracy of the servo motor is determined by the resolution of the encoder. Motor series: low inertia, medium and small capacity.
Using a serial absolute / incremental encoder.
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 torquee .
2, a wide range of operaation MITSUBISHI MR-J4-20B-RJ.
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, comparredd with the same capacity DC servo motor, the volume is large and the weight is heavy,
So it is only suitable for 0 MITSUBISHI MR-J4-20B-RJ. 5-100W small power control system.
