Mitsubishi servo system failure problem

For the first time to use Mitsubishi inverter, the operation command and frequency command equipment may not be familiar, especially related to the setting of domestic inverter, the two parameters are separated. Mitsubishi's, on the other hand, are collectively referred to as the form of operation. ...

1. Whether there is abnormal change in the sound during the operation of the equipment, including whether there is oscillation during the operation of the motor. 2. Whether the ambient temperature of the inverter installation is too high or too low, the working temperature is generally required to be in the range of -10°C - +40°C, and it is better to be about 25°C. ...

1. The starting torque that makes the mechanical equipment roll from a standstill state is usually positive, and generally larger than the torque required to maintain constant velocity movement, such as most feeders, material conveyors, mixers, mixers, etc., it may reach the additional torque of the Yuan Yuan Yuan Yu Yao Yuan Yuan ...

You can use two commands: TWR (Time Write) command and TRD (FNC166) TRD(P) command to adjust the built-in time. 1. TWR (Time Write) command Instructions to write time presets to the built-in real-time clock: Clock ...

FX2N-16MR Discontinued Replacement: FX3U-16MR/ES Input: 8 DC 24V Drain Output: 8 Relay FX2N-16MR-ES/UL Discontinued Replacement Model: FX3U-16MR/ES Input: 8 points DC24V drain/source output: 8 points Relay FX2N-16MS ...

(1) Eliminate finger tremor: use the differential instruction DIFU (13) to retrieve the rising edge of the button to send the electrical signal, and the PLC only executes it once in an execution cycle, and then prevent such misoperation; (2) Unconscious operation: (1) Optimize the display function and use different fingers...

Origin regression command with DOG lookup function Mitsubishi PLCFX3U origin regression command with DOG lookup function: DSZR. 1. The workbench runs in the direction of the value reduction of the current value register (generally runs in the opposite direction M8342 ...

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. Characteristics of the output reactor: 1. It is suitable for reactive power compensation and harmonic control 2. The primary effect of the output reactor is to compensate for the influence of long-line distributed capacitance, and output harmonic current according to the press; 3. Effectively protect the Mitsubishi inverter and improve the power factor, which can block the ...

1. The acceleration and deceleration time constants are at fault. Solution: Increase the acceleration and deceleration time constants to check whether it is normal. 2. The torque constraint value is abnormal. Solution: Increase the torque constraint value to investigate whether it returns to normal. ...

The MELSEC iQ-F series of small PLCs completes the high-speed system bus, supports a variety of networks, enriches the built-in functions, and makes it more convenient to use. From stand-alone use to network-based system proposals, we strongly support the needs of customers for "cutting-edge products in the manufacturing industry". Using the MELSEC iQ-F...

Low-power Z024 series inverter, our common problems include OC, ERR, no appearance, etc. There are two possible causes of OC. (1) Aging of the drive circuit Because the use of a long period of time will inevitably lead to the aging of components, which will cause the driving waveform to occur.

01. Base system problem In Mitsubishi PLC, binary, octal, decimal 10, hexadecimal, 2-10 (BCD), etc., we need to master the conversion of 2-8 base. 2-8, the binary number is remembered from the back, every 3 dividends in a group, each group is separated into 8 bases, such as 1 ...

In the case of impact loads such as electric welding machines, electric arc furnaces, rolling mills, etc., the voltage often flickers; In a workshop, when there are multiple Mitsubishi inverters and other capacitive rectifier loads working, the harmonics that occur are very serious pollution about the quality of the power grid, and there is also considerable damage to the equipment itself.

1. If the problem code E.OC1 is displayed on the screen of the Mitsubishi inverter, it means that the overcurrent may speed up the operation when the inverter is accelerating. We need to check whether the output of the inverter is short-circuited and whether the main power supply is operating normally; ...

In GX Works3, there are three types of security settings: block password, security key, and file password. The block password is for the program to prevent others from reading and writing changes, only for the program; The file password is for the PLC to prevent others from reading and writing changes. Security keys are both capable of ...

There is electrostatic capacitance between the input and output wiring of Mitsubishi inverters and other wires, between the ground and the motor, and there is a leakage current flow. The leakage current value is affected by factors such as electrostatic capacitance and carrier frequency, and the leakage current is high when the carrier frequency of the inverter is set high and the leakage current is operated under low noise conditions.

TOKYO, March 25, 2020 – Mitsubishi Electric Corporation (TSE: 6503) today announced that it has developed a new technology that integrates power devices, passives, sensors, and other embedded components on the same substrate and performs the dispensing at 100kW (continuous) power.

Press the abort button SB1, the contactor KM coil is de-energized, and the auxiliary normally open contact of the KM connected in parallel with SB2 is disconnected to ensure that the KM coil continues to lose power after the button SB1 is released, and the main contact of the KM connected in series in the motor circuit is continuously disconnected and the motor stops. Auxiliary to the KM in parallel with SB2 ...

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, ...
