Delta inverter failure and maintenance

In order to ensure the reliability of production, when Delta's inverter is planned to be equipped with power drive, in addition to meeting the power drive requirements, the remaining torque increases the consumption of active power. When using cost-effective Delta inverters to regulate the speed, if the flow requirements are reduced, by reducing the rotation of the pump or fan...

1. One is a triode type photocoupler, such as PC816, PC817, 4N35, etc., which is commonly used in the output voltage sampling and error voltage amplification circuit of the switching power supply circuit, and is also used in the digital signal input loop of the inverter control terminal. The structure is the simplest, and the input side consists of a light-emitting two...

(1) Considering that the power supply is inconsistent at the time of power-on, the load is short-circuited, and the rational load may present a reverse voltage, the output end of each power supply connected in series should be set up with two anti-parallel tubes, and the forward additional current of the two * tubes should not be less than the additional output current of the power supply, and the reverse breakdown voltage should not be less than ...

In the process of repairing the inverter, it is found that because of the back electromotive force in the stator winding, the electromotive force in the synchronous generator state and the self-induced electromotive force in the self-induced rotor, the current impact must have a negative impact on the motor, the inverter (Variable-frequency Drive, ...

1. What is a Delta inverter? Delta inverter is a device that converts the power supply (50Hz or 60Hz) into a communication power supply of various frequencies to realize the variable speed operation of the motor.

DC governor is a kind of motor speed regulation equipment, including motor DC governor, pulse width DC governor, thyristor DC governor, etc. Generally, it is a modular DC motor governor, which integrates power supply, control and drive circuits, selects three-dimensional structure layout, and selects micro-power consumption elements for control circuits.

1: What is the difference between servo motor and general motor? The biggest difference between servo motors and general motors is the motor rotor and reaction equipment. The surface of the servo motor rotor is pasted with a strong magnetic plate, so that the magnetic field generated by the stator coil can control the orientation of the rotor, and the acceleration and deceleration characteristics are ...

The inverter is the pioneering work of Delta Automation, and it is also the largest selling product of Delta Automation. In the highly competitive market, Delta inverters have always maintained a strong growth momentum and made great achievements in the high-end product market and the economic product market. Delta continues to launch high-end products ...

(1) Ambient temperature: The inverter is the same as other electronic equipment, and has certain requirements for the ambient temperature, which is generally "-10-+40°C". Because the inverter is a high-power electronic equipment, it is easy to be affected by the operating temperature, but in order to ensure the safety of the inverter...

If you want to reduce the fault rate of Delta inverter, it is necessary to check it daily, and what are the detailed items? Delta inverter fault repair ...

Fault 1: Overcurrent in acceleration Clarification: Overcurrent in acceleration Solution 1: Check whether the wiring from U-V-W to the motor is poorly insulated; 2: Increase acceleration and deceleration time; 3: Replace the inverter with a larger output capacity; 4: Reduced (P54) torque ...

With the increasing demand for system switching power supply by computer technology, Delta UPS uninterruptible power supply R-2K series products have been paid more and more attention, and gradually developed into a kind of electrical engineering with the effects of voltage stabilizer tube, frequency stabilization, filtration, anti-electromagnetic and frequency emission influence, anti-operation voltage swimming, etc.

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 ...

Engined DC: 1K=36V, 2K=72V, 3K=96V, 5K, 6K, 10K=192V UPS power supply accounting formula: 1KVA (volt-ampere) =700W (watt) =1000VA (volt) UPS power supply x extended time + starting DC = how big the battery is Start DC + V number of battery = how much power is distributed ...

PLC progressive scanning standard work preparation. Abundant programming language: instruction statements; ladder diagram; SFC。 Abundant instruction statements: 45 instruction varieties, including 28 root instructions and 17 usage instructions. 350 step law capacity. uS-level root directives ...

The servo system is mainly composed of a servo controller, a drive circuit, a servo motor and the corresponding reaction testing equipment. (1) Servo motor Servo motor refers to the motor that controls the mechanical components in the servo system, and the servo motor has an encoder inside, which can respond to the movement in real time.

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. ...

Short-circuit maintenance (overload maintenance) is an important function of circuit breakers, and the reason why this function is achieved is that the circuit breaker senses the temperature in the circuit through a thermal iron plate. Once the temperature in the circuit is too high, it is transmitted to the mechanical mechanism in the circuit breaker for trip maintenance. ...

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.
