Delta's soft starter component role

After the installation of the Delta inverter is completed, disconnect the output of the inverter, use the diode file of the digital meter to measure the input and output of the inverter before the power is not turned on to ensure that there is no short circuit, and then turn on the operating power supply of the inverter.

Robot harmonic reducer is a kind of power transmission organization, which uses the speed converter of the gear to reduce the number of revolutions of the motor (motor) to the required number of revolutions, and obtains a larger torque organization. The scale of use of the reducer is quite extensive, if the noise of the reducer is too loud, it will hinder people ...

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 ...

　　After the long-term operation of the industrial tablet, there is a lot of dust in the chassis and the temperature of the chassis is high. At this time, it is very simple to cause the disk failure of the industrial tablet computer, the product quality problems of the hard disk itself and the failure problems caused by the working environment. ...

Parameter settings P1-XX are the basic parameters P1-00 pulse method selection, *** bit selection is 2, that is, pulse train + direction P1-00 signal logic picking, the third digit is selected as 0 or 1, which is the positive logic or anti-logic, X0XX or X1XX P1-01 Control form selection, pick ...

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 ...

There are many setting parameters of the inverter, each parameter has a certain selection range, and the phenomenon that the inverter can not operate normally is often encountered in the application due to the improper setting of a single parameter, so the relevant parameters must be set correctly. ...

Optimized structure with lock-free screw terminals to plan the supply of bento ...

1. Before the inverter is energized The temperature and humidity of the surrounding environment should be detected first. Too high a temperature will cause the inverter to overheat the alarm. When severe, it will directly lead to damage to the power supply device of the inverter and short circuit of the circuit; Excessive humidity of the air can lead to a direct short circuit inside the inverter. When the inverter is in operation ...

When using the motor dragged by the inverter, sometimes the motor flutters and the over-fire flutter may burn out the motor and cause immeasurable losses. So what is the reason for this phenomenon? 1. The motor is damaged ...

Delta's VFD series of inverters has established a wide 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 the most diversified choices ...

　　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 steel sheet, so that it can be produced by the stator coil.

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 ...

Static quizzes 1. Test the rectifier circuit Find the P and N ends of the DC power supply inside the inverter, adjust the multimeter to the resistance X10 gear, connect the red watch rod to P, and separate the black watch rod to R, S, T. Instead, connect the black watch rod to the P...

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 ...

In life and production, leakage switches are often used. But the inverter is not used much at some times. Most manufacturers often use leakage switches as the main switch when installing switches in the workshop. When the frequency conversion control is elected, the problem comes out, and the leakage switch is always tripped after a little moment...

1. The inverter must be selected correctly. 2. Read the product manual carefully, and wiring, device and application in accordance with the requirements of the manual. 3. The inverter device should be firmly grounded to suppress radio frequency disturbance and avoid electric shock caused by leakage of the inverter. 4、 ...

The ways to reduce the soft fault of the inverter are: 1. Detect the overvoltage and undervoltage of the inverter; 2. Detecting overcurrent is the most frequent phenomenon of frequency conversion alarm. Generally, the overvoltage alarm is generally presented at the time of shutdown, and the primary reason is that the deceleration time is too short or the braking resistance and braking unit have ...
