My company has a spraying machine that uses the PLC control of Mitsubishi FX MR 128?

If the equipment is working properly, the equipment here refers to the PLC, or the PLC-controlled equipment. If the PLC controlled equipment is normal, then you can see if the electrical voltage is required 110V. If it is a PLC stubble, and the control equipment is not normal, then you only have to check your circuit, I have also had this problem when I connected 24V, and finally there is a problem with the circuit, you can check it.

The output voltage of the PLC is external, if you need to work is 110V, add 110V, if you need 220V, add 220V, and if you don't need to output Y, you can add different voltages.

It can't be connected directly to a load cell, unless you're using a load cell that can output a standard signal, which I do similarly. First of all, you look at the description of the sensor, which has.

Please pay attention to observe whether the input voltage of the output terminal is 220V, or all of them are 110V, if it is not the same, you will talk about the situation, in fact, when the PLC relay outputs, the output terminal only plays the role of on-off through logic control relay, and has nothing to do with anything else.

In fact, the PLC module does not have an output voltage level, and the output voltage level depends on the voltage level you access to the common end, and the voltage level of the common end must be 110V and 220V

Yes, the external high-speed input signal is x0 x7, e.g. the high-speed counter output can be controlled when the pulse signal from the encoder is collected.

MR is a relay type.

MT is a transistor type.

The relay is simply similar to the intermediate relay transistor type seen in the control cabinet, which is turned on and off by a thyristor, similar to a solid-state relay.

Which is longer lifespan, intermediate relay or solid state relay? Which can be switched on and off quickly and frequently at high speed? Go without saying.

So only the transistors support steppers and servos.

Except for not being able to emit high-speed pulses, it can be played.

The servo should be MR-JE series, not MR-JB bar-drain type, collector pulse control;

Follow the drawings and you're done;

DICOM and OPC are connected to DC24V

Docom to 0V

MR indicates that the output contact is a relay passive contact, which can control the AC and DC circuit within the specified current, and the switching frequency (about <5Hz) and life are limited.

MT indicates that the output contact is a transistor, which is generally used to control 24V DC circuits, high switching frequency (up to 100kHz at specific high-speed points), and long service life.

MR is the relay output with a slow speed and a high withstand voltage value.

MT is the transistor output with a high speed and low withstand voltage value.

You can learn to make a copy until you get to two points.

1.Learn about stepper drives.

signal, recognize which is the forward signal and which is the reverse signal;

2.To learn the pulse-specific instruction PLSY, first confirm the PLC type you selected, if it is FX, please confirm that it is the MT (transistor output) type, if not, please change it, because MR cannot output high-speed pulses. The next step is the learning of PLSY instructions, which controls two data, one is the speed, that is, the frequency of the stepper motor, and the other is the number of pulses, that is, I trigger it once, how much the stepper motor acts.

You can refer to the "Mitsubishi FX Programming Manual" for learning instructions, or give you a brief introduction here.

plsy d1 d2 s

D1 is the frequency, D2 is the pulse quantity, and S is the output port (FX1S, FX1N, and FX2N only have Y0 and Y1 ports, and FX3U has Y0, Y1, and Y2 ports).

Assign the appropriate values to d1 and d2, and add the appropriate trigger conditions to the command to achieve the action.

Mitsubishi's official website is very good, and the stepper motor controls the PLC with PLSY commands. The servo motor should have a dedicated driver. I haven't done it either, but I can look into it.

PLC is to control the position of the step by sending PLS pulses, and the PLS pulse function of Y0 and Y1 ports can be used, and there are detailed application examples in the Mitsubishi PLC manual, just follow it.

1.Manual debugging can be reversed, indicating that the servo is no problem.

2.The servo drive sets the pulse + direction; Set the location mode.

3.The program can do DDRVI commands, put the number of pulses with positive and negative signs, speed test. For example: DDRVI(K10000 K1000 Y0 Y1) DDRVI(K-10000 K1000 Y0 Y1).

Maybe the servo drive operation mode is selected wrong, you should choose pulse + direction, you check, Mitsubishi's servo has not been used, but it is similar to Panasonic, you try it.

The wiring diagram of the Rhombus PLC (FX3U-48MT) control Mitsubishi servo MR-JE-20A is as follows:

Components of the PLC system and the functions of each part:

1. System composition.

2. The role of each component.

1. CPU operation and control center.

Plays the role of "heart".

2. Memory.

Semiconductor circuits with memory functions.

3. Input and output interfaces.

Mitsubishi MR-J3-20A I have a copy here, and it should be the same as MR-JE. The diagram below is the wiring diagram of CN1.

MR-J3-100B uses high-speed serial communication, that is, the server can be controlled by using a communication line in series, saving the cumbersome wiring of the A series, I have the impression that the FX series does not seem to have such a communication module, so it should not be possible to use FX to control B, the communication mode is different from 232, A, Q series PLC can be used. For control, use the signal cable to connect the servo, divide the station number (if you use multiple servers), and then program it, programming is the key.

This is the same as when you use MR-J3-100A, and the one with B doesn't have a communication panel, and you have to use a computer to do it, and if you get it right, it's the same as the one with A.
