Delta's power supply series application considerations

1. Open-loop control There is no reverse connection between the controller and the controlled target, and the control is carried out in one direction. Strengths: Simple, stable and reliable. If the characteristics and parameter values of the components that make up the system are relatively stable, and the external disturbance is small, the open-loop control energy Enough...

1. Vibration circuit: the leakage-source and R4 of the main winding N1 and Q1 of the switching transformer are the channels of the power supply operation current; R1 provides the starting current; The self-powered windings N2, D1, and C1 constitute the power supply voltage of the vibrating chip. The normal operation of these three links is the prerequisite for the power supply to vibrate.

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 ...

With the development of electronic semiconductor information technology, technologies such as the Internet of Things, big data, and cloud channels are showing a trend of hundreds of schools of thought, which also drives the rapid development of intelligent production. Intelligent production also puts forward new requirements for controllers: high speed, large capacity, miniaturization, networking...... In order to ...

This example is an example of the equipment used to connect a Modbubs to Profinet gateway to a Delta inverter, and the equipment used is a Siemens 1200 PLC, a Delta inverter, and a DJI Modbus to Profinet gateway. 1、Mo ...

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.

Delta's VFD drives have now established a wide range of brand awareness in the industrial automation market. Each series of products is designed for different operation needs such as torque, loss, overload, overspeed work, etc., and is adjusted according to different industrial machinery attributes; It can provide customers with a variety of choices, and a wide range of ...

1. Touch screen download program (1) Device software DOPSoft; (2) The communication line uses a square port data line; (3) device drive; (4) Configuration screen; (5) In the Stuff, select Download All Materials. 2. Communication settings (1) Touch screen settings ...

First, the selection of output module The output modules are divided into transistors, triacs, and contact types: (1) The switching speed of the transistor type is fast (generally 0.2ms), but the load can be small, about 0.2-0.3A, 24VDC, suitable for fast switching, signal contact...

1. The necessity of braking resistance If the regenerative energy that occurs during deceleration and descent in the application is too large, there is a possibility that the voltage of the main circuit inside the inverter will rise, causing damage. Due to the built-in overvoltage maintenance function in the inverter, the overvoltage of the main circuit (O ...

The inverter used in industry is divided into two types: single-phase and three-phase, which is distinguished from the voltage supplied by the main circuit, which is the main circuit to be connected to RST three-phase 380 volt alternating current, and the output is connected to the UVW three-phase line to the motor; And the single-phase is the main circuit connected to the single-phase 220 volt LN alternating current, the output is the same ...

Delta's thermostats are only available in the DTE series (variety 1.5 and above) with the "slope control" function. Illustrate the following examples: For example: PV=20°C, SV=100°C, slope 10.0°C/min Then (100 – 20)/10.0 ...

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 ...

We really talked a lot about the relevant knowledge of inverter repair, but we talked less about the main reasons for protecting the main power supply circuit. Then take a look at the introduction below: When there is a fault in the main power supply circuit of the inverter, in addition to selecting each component to match the corresponding power, it should also ...

1. When the device is installed, leave the place with high voltage and strong high-frequency noise to prevent disturbance. Prevent use in places where the following conditions occur: (a) Excessive dust and corrosive gases; (b) high humidity and very high radiation; （c） ...

Delta's inverter problem 1: Communicate with the motor driver to explore the formation of overvoltage conditions on the internal DC high-voltage power supply side Check whether the keyed operating voltage is in the field of the additional value of the communication motor driver keying operating voltage, and detect whether there is a surge operating voltage formation If it is due to ...

1. Restore the inverter to factory settings, press the "ENTER" button to enter the parameter setting interface, and press it continuously until it is 00-00 and then stop. Press the number up button to change to 00-02. Press the "ENTER" key again, the panel value will show 0, press the number up key to change it to 9. Press the "ENTER" key, break ...

The main problems of the iron core of the small electromagnetic relay are that the armature cannot be sucked after being electrified: This may be due to broken coils, foreign matter between the moving and static cores, and low power supply voltage. It should be patched on a case-by-case basis. When energized, the armature is noisy: This may be because of the ...

Delta's inverter energy-saving method is mainly manifested in the application of fans, pumps, and hoists. In order to ensure the reliability of production, all kinds of production machinery are designed with power drive, and there is a certain amount of surplus. Power Factor Supplement ...

1. To switch the motor of the power frequency, the parking method is set to free parking, and it is important not to park softly 2. Intercept the contactor of the motor from the output end of the inverter, and the control stop button and the inverter parking button are the same composite button, that is, when the inverter is pressed, the inverter parking will be followed by the contactor line.
