1. Ability to adapt to the environment 1.1 Ability to adapt to grid voltage fluctuations When the motor on the bus starts in a group, when the largest motor unit on the bus starts, the influence on the operation of the inverter, which is related to the input voltage fluctuation range parameters promised by the inverter.

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 ...

Daily View Item 1: Check whether the sound of the motor changes abnormally during operation, including whether there is vibration during the operation of the motor. Project 2: Check if the environment of the inverter unit has changed. For example, whether the ambient temperature is normal. Familiar with Delta's inverter ...

What is the effect of speed regulation of fan inverter? According to the query materials, in industrial production, the throttling loss of the damper, baffle and other related equipment of the fan, as well as the protection and maintenance costs account for 7%-25% of the production cost.

1. Initialize parameters Before wiring, initialize the parameters. On the control card: select the control method; Reset the PID parameter to zero; When the control card is powered on, the enable signal is closed by acquiescence; Save this condition to make sure that the control card ...

(1) The wiring interval between the braking unit and the inverter, as well as between the braking unit and the braking resistor, should be as short as possible (the wire length should be less than 2m), and the wire cross-section should meet the requirements of the braking resistor discharge current. (2) The brake unit is working ...

Outstanding drive characteristics The overload capacity is up to 150% / 60 seconds, 200% / 3 seconds, suitable for constant torque, variable torque, constant power and other loads Support induction motor, permanent magnet synchronous motor, optional PG card for high ...

(1) When the speed of the motor is controlled by the Delta inverter, the noise and temperature rise of the motor are higher than that of the frequency of the motor. When the motor is running at low speed, because the speed of the motor blades is low, the temperature rise of the motor becomes high.

Delta's A2 series servo system is one of the more common and used servers on the market today, and the following describes the fault details of the azimuth controller in the repair of Delta's A2 servo drive and the corresponding repair methods Delta ...

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...

When selecting a Delta servo motor, in principle, the selection should be based on the load conditions. There are two types of loads on the motor shaft, namely damping torque and inertial load. Both loads should be calculated correctly and their values should meet the following criteria: 　　1) When the machine is running with no load, in the whole speed range, Delta ...

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.

There are three speed regulation methods for DC motors: armature loop string resistance, armature voltage regulation and speed regulation, and weak magnetic field speed regulation. The three speed regulation methods can achieve stepless speed regulation. 1. Armature loop string resistance The applied resistor is connected into the armature circuit to achieve the purpose of speed regulation. Speed Direction: Add ...

Installing a variable-frequency drive (VFD) on the power frequency motor can complete the accurate control and speed regulation of the motor, and improve the efficiency and accuracy of the motor. However, if not properly equipped and used, it may cause the following hazards: ...

1. Programmable manipulator AH series Delta's AH series modular controllers provide automation system solutions for high-end applications. The AH series adopts a comprehensive modular design, and on the basis of Delta's research and development skills, it has developed ...

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. ...

Delta-B series inverter inverter output module is damaged and the drive circuit is seriously damaged: the drive integrated circuit T250V or burst, or the output terminal and the power supply ground are short-circuited, the filter capacitor is sprayed, the regulator tube is broken down or open, the resistance is open or the resistance value increases, and the circuit board carbonization is damaged.

The speed control on Delta's inverter is mainly as follows: 1. Adjust the variable resistance directly from the surface of the Delta inverter 2. External analogue voltage or current signal to adjust 3. Take advantage of the multi-function of the inverter ...
