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. ...

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.

The transformer DC resistance tester uses the 32-bit ARM core as the processing center to control the whole machine, actively complete the functions of self-calibration, current stabilization judgment, data processing, resistance value display, etc., and can measure the DC resistance of various types of transformers and transformers. ...

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 ...

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 ...

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 ...

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. Because usually the inverter has a built-in overvoltage maintenance function, the main circuit overvoltage (O...

Intelligent houses are selected with fully automatic automatic control systems to consider the diverse requirements of community owners, managers and users in housing management methods. In the new project of Yili Group's Food Science R&D Trend Management Center, under the framework of opening to the outside world, Damei has made use of Loytec ...

1. Use a vacuum cleaner with a plastic nozzle to completely clean the inside and outside of the inverter cabinet to ensure that there is no excessive dust around the equipment. 2. Check the ventilation and lighting of the inverter room, and the ventilation equipment can work normally. 3. Check the inverter ...

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 ...

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.

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.

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 ...

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...

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 ...

Before operating the MS300 series products, please read and pay attention to the relevant safety information to ensure your own safety and product safety. When operating the wiring and installing the inverter, it is necessary to confirm that the power supply is closed. After blocking the communication power supply, the inverter POWER indicator (located in ...

Delta's thermostat is a commonly used temperature control device, which can adjust the temperature according to the user's needs, and then achieve the intention of saving energy. The effect and use of Delta thermostats are also very widespread, so let's introduce the effects and uses of Delta thermostats. ...

Delta's inverters should be thoroughly inspected for the first time or after long-term installation. The items and methods of inspection 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 dried for 4 hours (60°C) or ...
