Delta's inverter adjusts the motor speed mode

1. Circuit breaker A circuit breaker is a device that can be manually or automatically controlled, and is used to control the on/off of the system power supply in the equipment circuit system. When there is a suspicion that there is a defect in the electrical system of the equipment, the primary functional part of the power supply should be checked. Under normal circumstances, when in the ON state, the input input ...

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...

Inverter is a kind of speed regulation equipment, where is there a place to use motor speed regulation, especially asynchronous motor speed regulation, will use inverter, now it is mainly used in industrial equipment on a large scale, because the motor is the heart of industry, and three-phase asynchronous motor occupies the vast majority of the share, ...

(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 ...

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.

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 ...

In view of the rapid transformation of the industry, Delta has specially proposed a total linear motor solution, deploying various communication interfaces, extending the evolved model ASDA-A2R from ASDA-A2 as a linear horse driver, and deploying Delta's high-speed bus controller and axis card to form a complete linear motor ...

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 ...

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: 1. After the equipment is powered on, it becomes ...

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 to the armature circuit.

1. No-load energizing test of inverter 1. Ground the grounding terminal of the inverter. 2. Connect the power input terminal of the inverter to the power supply through the leakage maintenance switch. 3. Check whether the factory display window of the inverter is normal, if it is incorrect, it should be reset, no ...

In the inverter problem, it is often encountered that the energized panel does not appear. Generally speaking, the problem of the inverter panel not showing up is usually caused by three parts, one is the poor contact of the contactor, the second is the control panel of the inverter, and the third is the damage of the power module that supplies power to the control panel.

1. Set temperature: Press the SET button to set or view the temperature set point. Press the SET key digital tube character beginning flash, indicating that the appearance has entered the setting state, press the △ key to increase the set value, press the ▽ key to decrease the set value, press and hold the △ key or ▽ key The data will change rapidly, press the SET key again The appearance back ...

Driven by consumption promotion and product diversification, the manufacturing industry's demand for automation and intelligent promotion in production and processing is also increasing. In the production process, the processing of "large and heavy" items is often difficult to control accurately, and the deviation of orientation is not as easy as that of "small" items. To this end ...

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 ...

Delta's inverter should be thoroughly inspected for initial installation or long-term use. The items and methods to check are as follows: 1) Check whether the Delta inverter is damaged, whether the metal parts are rusty, and whether there is frost. If there is frost and condensation, it should be dry for 4 hours (60°C) or in ...

As we all know, the inverter has many maintenance functions, such as overcurrent, overvoltage, overload maintenance and so on. With the continuous improvement of industrial automation, frequency converters have also been widely used. This article will explain to you how to use a multimeter to measure the quality of the inverter. Need...

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 ...

1. Control the starting current of the motor: when the motor is directly started through the I frequency, it will generate 7 to 8 times the rated current of the motor, and this current value will greatly increase the electrical stress of the motor winding and generate heat, thereby reducing the life of the motor. The acid frequency speed regulation can be started at zero speed and zero voltage (can also be ...
