1. Try to avoid using "double words" when you can use "words", and try to prevent using real numbers when you can use integers. 2. Give priority to the use of surplus (other than hardware connection) IB, IW, ID, QB, QW, QD, followed by M and S; 3. Try to prevent the transformation of data types, ...

After overhauling and confirming that all connections of the system are accurate, power on the relevant modules until the card indicator is normal. The initiation process of the system after the scheduled repair is as follows: (1) Power supply. Open power supply equipment (including throwing up...

Torque control: Torque control is based on external simulation imitation typing or direct address assignment to set the output torque of the motor shaft. For example, 10V matches 5Nm. When the external simulation simulation is set to 5V, the output of the motor shaft is 2.5Nm. If the load of the motor shaft is less than 2.5Nm, then when ...

1. Aging of drive circuit Due to the long-term use, it will inevitably lead to the aging of components, and then cause the drive waveform to be distorted, and the output voltage will be unstable, so OC alarm often appears as soon as it is running. ...

1. CPU function As a MELSEC IO-F series PLC actuator, it is equipped with executable structured programs and multiple program actuators, and can be written to ST language and FB. 2. Built-in analog input and output (alarm output by the way) Built-in 12-bit 2-channel analog input ...

1. Occasions to choose a servo motor with brakes: The servo motor is mainly loaded through the motor shaft, if the load driven by the motor shaft is in the straight direction, after the whole control system is powered off, the load on the servo motor shaft will be driven to run down under the effect of gravity, so that ...

The motor of the core and winding coil is what we commonly see in our daily life, and what is the heating principle of this Mitsubishi servo motor by comparing it with other motors? We know that the winding has resistance, and the loss will occur when energized, and the size of the loss is proportional to the square of the current of the resistance.

There is a very common kind of circuit in Mitsubishi PLC - the persistence circuit. The insistence circuit means that when the external input switch is a button, it can be pressed once through the insistence circuit to insist on the output, similar to the self-locking in the electrical diagram. We use Mitsubishi PLC as an example to write a sticking circuit. ...

1. Mitsubishi PLC's analog signal control inverter Hardware: FX1N, FX2N PLC hosts, equipped with 1 simple FX1N-1DA-BD extended analog output board; or analog input-output hybrid module FX0N-3A; or FX2N-2DA with two outputs; or four outputs ...

The encryption process is as follows: ** Open the serial port for the first time [00000000] IOCTL_SERIAL_SET_BAUD_RATE Baud Rate: 9600 (Set baud rate here) [00000000] IOCTL_SERIAL_SET_LINE_CONTROL StopBits: 1, Parity: Ev ...

During the operation of the Mitsubishi servo motor, it may be possible to display an AL.50 alarm under certain circumstances (such as after a period of continuous operation), what is going on? And how to solve it? First of all, we need to know that the reason why the AL.50 alarm is presented is because the Mitsubishi servo ...

01. Base system problem In Mitsubishi PLC, there are binary, octal, decimal, 10, 2-10 (BCD), etc., we need to master the conversion of 2-8 base. 2-8, remember the binary number from the back, divide every 3 into a group, and each group is converted into octal respectively, such as 1 ...

1. The equipment layer/fieldbus CC-Link equipment layer is a field network that connects PLC and other control equipment, sensors and drive equipment, which is the lowest layer of the entire network system. The CC-Link fieldbus connection is adopted, and the number of wiring is greatly reduced, and the maintainability of the system is improved. Combine...

1. Check whether the three-phase electricity of the motor is balanced (1) If the three-phase voltage of the motor is unbalanced, then check whether the three-phase voltage at the output end of the Mitsubishi inverter is balanced. (2) If the three-phase voltage of the Mitsubishi inverter is also unbalanced, the problem is inside the Mitsubishi inverter, and it should be investigated.

1. The output side of the inverter is short-circuited, such as the connection line between the output end and the motor, or the short circuit inside the motor, etc.; 2. The inverter itself is not working properly, such as the two inverter equipment of the same bridge arm in the inverter bridge are constantly alternating in the working process ...

1) LD (take instruction) A command to connect a normally open contact with the left bus, and every logic line that starts with a normally open contact is used with this instruction; 2) LDI (Reverse Instruction) A normally closed contact is connected to the left bus to the instruction, each ...

In the process of operation, low-voltage electrical appliances will present problems due to improper use or long-term operation of aging components, and there are many kinds of problems, and the common problems are analyzed and dealt with. 1. Contact problems and repairs The contact is the primary component of the low-voltage switching coupon, ...

1. The servo mainly relies on the pulse to position, basically it can be understood in this way, the Mitsubishi CNC system maintenance servo motor receives a pulse, and it will rotate the angle corresponding to the pulse, so as to achieve displacement, because the servo motor itself has the function of sending out pulses, so the servo motor ...

1. Torque control: Torque control is based on external simulation simulation type or direct address assignment to set the output torque of the motor shaft. For example, 10V matches 5Nm. When the external simulation simulation is set to 5V, the output of the motor shaft is 2.5Nm. If the load on the motor shaft is less than 2.5Nm, ...

The tension controller can be called the tension manipulator, which is generally equipped with magnetic powder brake, magnetic particle clutch and tension detector, and is suitable for winding, unwinding, tension control, etc. It also has the so-called manual control function, which generally refers to the ability to give a certain amount of output through the tension manipulator ...

It has become an irreversible trend to drive the motor through the inverter, and in the actual application process, because the matching relationship between the inverter and the motor is not very reasonable, it often leads to some problems. When selecting an inverter, you should fully understand the load characteristics of the equipment driven by the inverter. Ms. Ginseng ...
