Servo motor refers to the engine that controls the operation of mechanical components in the servo system, and is a kind of auxiliary motor indirect transmission device. The servo motor can make the control speed, azimuth accuracy is very precise, and can convert the voltage signal into torque and speed to drive the control target. Servo motor rotor speed ...

Major Failures and Analysis: 1. Motor encoder alarm 1. The cause of the failure (1) Wrong wiring; (2) electromagnetic interference; (3) Encoder hardware damage caused by mechanical vibration; (4) Pollution caused by the on-site environment; 2. Troubleshooting ...

Ladder concept: It is a ladder pattern composed of graphical symbols that indicate the programming elements inside the PLC. Rules for writing ladders: Suitable for the left bus, finally the right bus The contacts should be drawn on the horizontal line, not ...

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. ...

Fault 1: Mitsubishi touch screen contact deviation Phenomenon: The direction of finger contact does not match the mouse arrow. Analysis: When calibrating the orientation after installing the screwdriver, there is no vertical contact with the bull's-eye. Solution: Recalibrate the bearing. ...

When you are ready to communicate through AJ71QE71, perform a ping in MS-DOS format to check if the connection is correct before the Mitsubishi PLC's GPPW starts to communicate. The support communicates with the Weilun touch screen through the serial port. ...

The reasons for the loss of the PLC program are the lack of battery power supply for the user's saved program, the internal circuit of the PC, the motherboard burned out due to the impact of external high voltage such as lightning strikes, etc., which will be encountered in our PLC control system. For example, the old type of plc such as the FX2N series, which has been discontinued...

Electrical characteristics view Mitsubishi inverters that have been running and placed for a long time, due to the influence of the environment and the aging of inverter equipment, it is necessary to check and maintain the electrical performance of Mitsubishi inverters regularly. A comprehensive review of the input, rectifier and inverter, DC input fuses found ...

When the inverter is used to form an active control system for control, in many cases, the PLC and the inverter are used together, and how to correctly connect the PLC and the inverter together has become the key to the success of the system. 1. PLC switch command signal input Inverter input ...

1. If the PLC stops in the middle of some outputs where the output is excited, then look for the signal that caused the next operation (input, timer, line, drum manipulator, etc.). The programmer will show the ON/OFF status of that signal. ...

Error Number (D8063): 6314 ERROR MESSAGE: PARALLELLINKERROR (PARALLEL OPERATION COMMUNICATION ABNORMAL) Error content: Parallel operation string abnormal Method: Whether the power supply of the two PLCs is on, and whether the connection wires between the main machine and the parallel operation module are correctly connected ...

The main steps in the planning and commissioning of the programmable manipulator application system (1) In-depth understanding and analysis of the process conditions and control requirements of the controlled target a. The controlled target is a controlled mechanical, electrical equipment, production line or ...

The connection of the Mitsubishi inverter FR-A800

Problem description: The power supply of the Mitsubishi FX1N-60MR-001 has no display (the safety guard, filter, temperature protection element, and rectifier are damaged). Inspection and repair: After the PLC is connected to the power supply, the power indicator (POWER light) does not light up.

1 SET Directive The SET instruction is called an enthronement instruction. Its function is: to drive the coil, so that it has a self-locking function, and insists on the connection condition. In the diagram, when the moving contact X0 is closed, the SET command is executed to turn on the Y0 coil. After X0 is disconnected, the Y0 coil continues to insist on the ON condition, ...

Q: Mitsubishi inverter E740 should ...

Q: When will I choose the A840 series inverter? A: A800 series inverters are generally used in heavy-duty occupations, such as lifting occupations, mixer occupations will use A800 series. At the same time, it is a vector inverter, so customers need to do closed-loop speed control, torque control may ...

Q: When will the CS84 series inverter be selected? A: CS80 series inverter belongs to the diversified function of small intelligent inverter, covering excitation control and general flux vector control, the volume is 57% of the same model, very fast, in some general functions can be used in this model ...

1. Use the switching signal of PLC to control the inverter The output point and COM point of the PLC (MR type or MT type) are directly connected to the STF (forward engine), RH (high speed), RM (medium speed), RL (low speed), and SG input ports of the inverter. The PLC can control the inverter through the program.

Mitsubishi FX5UCPU module has a built-in analog input as a voltage input (DC0-10V), In this way, it can be converted into an analog current input (DC4 - 20m). [Method used in current input (DC4 - 20mA)] FX5UCPU module only supports voltage ...
