Delta inverter is a device that converts the power supply (50Hz or 60Hz) into a communication power supply of various frequencies to complete the variable speed operation of the motor, in which the control circuit completes the control of the main circuit, the rectifier circuit converts the communication power into direct current, and the output input of the DC center circuit to the rectifier circuit is ...

One is hardware, similar to the CPU reset circuit, which gives the downtube a short high-level drive pulse during the initial power-up, and then the voltage drops to 0 to cut off the downtube. The second is the software, when the CPU is operating normally, it outputs a square wave pulse that only needs to be turned on by the lower three tubes, so that the upper tube ...

A3, B3 servo P5-97 Motion Control Mobilization Commands 0x0003 Maintenance Activation (Successful Return 0x1003) 0x0004 Maintenance Waiver (Successful Return 0x1004) If the wrong cipher code is entered, the error code Ennn will be sent back to exempt the loss, during which nnn indicates that there is a ...

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, ...

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. ...

If you want to reduce the fault rate of Delta inverter, it is necessary to check it daily, and what are the detailed items? Delta inverter fault repair ...

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) The AC servo motor works by means of a dedicated drive. Do not connect the commercial power supply (100/200V, 50/60Hz) directly to the line of the servo motor, otherwise the servo motor will not work properly and the servo motor will be permanently damaged. ...

1. The transmitter does not return to zero under no pressure? Answer: The cleaning method is to remove the transmitter from the device position, investigate whether the zero position is normal, and replace the pipeline sealing ring if it is normal. Check together whether the transmitter is perpendicular to the piping assembly, and if not, adjust the transmitter zero. ...

The low-voltage fuse cannot be used as an overload maintenance for the motor. It is necessary that the additional voltage of the fuse is greater than or equal to the operating voltage of the distribution line. The additional current of the fuse must be greater than or equal to the additional current of the melt. ...

1. The touch screen is controlled by PLC inverter 1. Now the general control of the inverter needs to use PLC to communicate with the inverter, read the information of the inverter, and then the touch screen communicates with the PLC in order to complete the control of the inverter to start, stop, and monitor the operation of the inverter.

Delta inverter is a device that converts the power supply (50Hz or 60Hz) into AC power supply of various frequencies to realize the variable speed operation of the motor.

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...

In order to ensure the reliability of production, when Delta's inverter is planned to be equipped with power drive, in addition to meeting the power drive requirements, the remaining torque increases the consumption of active power. When using cost-effective Delta inverters to regulate the speed, if the flow requirements are reduced, by reducing the rotation of the pump or fan...

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: ...

After the inverter is installed, 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, ensure that there is no short circuit, and then turn on the working power supply of the inverter.
