Delta's inverter external positive and reverse operation mode

Delta's motors are the most frequently used rotating things so far, and with the development and spread of Delta inverters, they need to be used in conjunction with inverters. However, in the process of combining inverters and motors, it is inevitable to encounter a lot of ...

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 ...

Step 1 Two inverters, two wires, and one power supply. Step 2 The inverter wiring defines the two inverters as a master and a slave respectively, the host port 485A is connected to the slave port 485A, and the host port 485B is connected to the slave port 485B. ...

Most inverter brand products can rely on the heat of internal electrical components to remove moisture during normal use. If you don't use it for a long time, it's easy to get wet. The chip pins, penetrating resistors, capacitors, and inductor pins of the DIP package will be severely rusted or desoldered, resulting in on-resistance ...

1. How to set the acceleration and deceleration time of Delta inverter? Solution(s): The acceleration time of Delta's inverter is the time it takes for the driver to accelerate from 0.0Hz to "high operating frequency". Deceleration time refers to the deceleration time required for the inverter to decelerate from "high operating frequency" to 0.00Hz.

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 ...

When you are using the motor, if you simply change the frequency, your motor will most likely be burned out. This problem is especially acute when the frequency is reduced. In order to prevent the motor from burning out, the inverter must change the voltage at the same time as the frequency. ...

Inverter is a modern factory in the use of a very ubiquitous equipment, this is a new type of equipment, the price is very noble, and the price of inverter repair is also very expensive, so in the process of using inverter, pay attention to the use of inverter, on the one hand, inverter, delay inverter ...

1. Control mode: i.e. speed control, torque control, PID control or other methods. After the control method is adopted, static or dynamic identification should generally be carried out according to the control accuracy. 2. Minimum operating frequency: That is, the minimum speed of the motor. When the motor is working at low speed, the ...

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.

The low voltage of the inverter mainly refers to the low voltage of the central DC circuit, and the reasons for the low voltage of the central DC circuit generally come from two aspects: ​ (1) Low voltage from the input side of the power supply The power supply under normal conditions ...

Rectifier circuits It consists of six rectifier diodes from VD1 to VD6 to form an uncontrollable full-wave rectifier bridge. Regarding the rated power supply of 380V, the reverse withstand voltage value of the diode should be 1200V, and the forward current of the diode is 1.414-2 times of the rated current of the motor. ...

Inverter acceleration form and deceleration form selection, also known as acceleration and deceleration curve selection. Generally, there are several forms of inverter, such as linear, S-shaped, semi-S-shaped, etc., and the characteristics and uses of each form are as follows: 1. Linear form This form makes the inverter's ...

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 ...

Delta's VFD-C200 series inverters adopt the design concept of ultra-miniature structure: small size, compact structure, reliable performance, and optimal heat dissipation design, which is convenient for users to install and debug. Taking into account the possibilities of the industrial production environment, this inverter is made of special materials and complies with the requirements of the IEC...

1. Acceleration and deceleration time The acceleration and deceleration time is usually confirmed by the rise and fall of the frequency setting signal. In the commissioning of Delta inverters, it is often used to set a long acceleration and deceleration time according to the load and experience value, and the frequency rise rate of the motor must be constrained when it accelerates to avoid overcurrent. When slowing down, ...

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...

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 ...

1. Delta's PLC power on running light does not light up, and the ERROR flashes, the reason may be: no program 2. Delta's PLC cannot communicate with the computer, which may be: RS23 port is broken 3. Delta's PLC power light does not light up: The power supply is bad ...

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 ...
