Solution to Delta inverter fault CE1 and CE2

Power transformers are used very frequently in daily livelihoods, in order to ensure the normal use of electricity, the safety and stability of the power transformer is the key point, once the transformer has a problem of prevention, it is necessary to quickly find out the cause and deal with it, take the transformer short circuit as an example, the damage caused by the insufficient treatment is ...

1. Inverter element - rectifier Since it is difficult to change the frequency of the communication sine wave in the form of communication, the first operation of the inverter is to convert the waveform into direct current. To make it look like an AC, it is relatively easy to operate the DC. The most important component of all inverters is a ...

When many engineers debug servo motors, they often have such a problem: why is my servo motor so slow, how can I improve the speed, and how much can the maximum speed reach? The basis for the confirmation of the speed method of the servo motor: the speed of the servo motor. ...

Reactors are also called inductors, and when a conductor is energized, a magnetic field will be generated in a certain space scale occupied by it, so all electrical conductors that can carry current have inductance in a general sense. However, the inductance of the energized long straight conductor is small, and the magnetic field generated is not strong, so the actual reactor is conductive.

Daily inspection item 1 of Delta's inverter problem repair: Check whether there is any abnormal change in the sound of the motor during operation, including whether oscillation occurs during the operation of the motor. Delta's daily inspection of inverter problem repair ...

Programming equipment: simple programmer, most only accept mnemonic programming, and some can also be programmed graphically (such as Japan's Toshiba EX programmable controller). The cluttered one has a graphical programmer, which can be programmed in the trapezoidal language. Some also have dedicated computers that can be used for other ...

1. Fault code: SE1 parameter replication error Fault Description: Keypad replication function error correct Solution: Keypad replication action errors, including communication delays, communication errors (Keypad received FF86 errors), and parameter value errors ...

Delta's programmable controllers, also known as Delta programmables, delta programmable controllers, delta programmable controllers, etc., are electronic devices specially designed by Delta for the industrial automation category to complete digital operations. Delta's PLC uses programmable memory to store execution logic inside it.

1. The shaft current of the motor is generated The current in the shaft-housing-base circuit of the motor is called the shaft current. Causes of shaft current: 1) Magnetic field asymmetry; 2) There is a wave in the supply current; 3 ...

In order to ensure the reliability of production, all kinds of production machinery are designed with power drive, and there is a certain surplus when designing and matching power drive. When the motor cannot operate at full load, in addition to reaching the power drive requirements, the residual torque increases ...

1. The transmitter does not return to zero under no pressure? Answer: The cleaning method is to remove the transmitter from the device position, investigate whether the zero position is normal, and replace the pipeline sealing ring if it is normal. Check together whether the transmitter is perpendicular to the piping assembly, and if not, adjust the transmitter zero. ...

If the inverter is to run the equipment again after being shelved for more than half a year, the probability of damage may be greatly increased due to many factors such as the placement environment, the service life of the inverter, and the load rate, and the failure usually presents the following problems: ...

Belt conveyor is a kind of continuous conveyor, which is one of the most important types of stationary or escorted cranes. The belt conveyor is the use of friction to convey the dynamics, with belts, steel belts, steel fiber belts and chemical fiber belts as a kind of adaptation to the transmission of materials and traction operations.

Low-voltage circuit breakers, commonly known as active air switches, are one of the primary electrical switches in low-voltage distribution networks. It can not only turn on and off normal load current, motor operation current and overload current, but also turn on and off short circuit current. It is mainly used as a low-voltage distribution line or a switch cabinet that is not often operated ( ...

The first step is type recognition: acknowledging whether the type of inverter is common to the type of inverter purchased. If not, ask the agent to return the item. Step 2: Shipping Acknowledgement: After opening the package, check whether the inverter is damaged during transportation. If there is damage, let the agent return ...

The external use resistor is an external operation form of the inverter, which controls the inverter through the external operation signal generated by the external starting switch and frequency setting potentiometer. The regular external voltage signal of different inverters is different. ...

Correct installation, operation and maintenance of the reducer is an important part of ensuring the normal operation of mechanical equipment. Therefore, when you install a planetary reducer, it is necessary to carefully assemble and operate it in strict accordance with the following matters related to the operation of the device. ...

1. Acceleration and deceleration time The acceleration and deceleration time is usually confirmed by the rise and fall of the frequency setting signal. In the commissioning of Delta inverters, it is often used to set a long acceleration and deceleration time according to the load and experience value, and the frequency rise rate of the motor must be constrained when it accelerates to avoid overcurrent. When slowing down, ...

The inverter of Delta's brand A series locks the keypad to correct the parameters, forming that most of the parameters cannot be corrected, and the manual does not clearly explain how to unlock the keypad lock, press MODE and RESET together to display P256 (P256 does not explain what it means in the manual), press ENTER...

1. The touch screen is controlled by PLC inverter 1. At present, the general control of the inverter needs to choose PLC to communicate with the inverter, read the information of the inverter, and then the touch screen communicates with the PLC to complete the control of the inverter to start, stop, and monitor the operation of the inverter.
