Variable speed drives (VSD – variable speed Drive), operating system, precisely controlling the speed and torque of the engine by energy savings and efficiency.However, the distance between the VSD and motor, is a critical factor that directly affect the performance of the system. Appropriate cabling is not done, harmonics, noise, and electromagnetic interference may occur. In this article, it is necessary to establish how the distance between the VSD and motor, it is possible [...]

The working principle of a manometer is a device transmission is rather simple. There is a potentiometer in the manometer, manometer is connected to the potentiometer and the sliding part of the needle. When the pressure is changed accordingly, the location of the sliding potentiometer portion also varies. In manometer is supplied on both ends of the potentiometer to the inverter and the power source that is connected to the floating part and the “0V” AI1 voltage between the feedback signal. 1. Manometer the transmission [...]

In general, constant torque applications typically super-heavy or heavy-duty to VFD (conveyors, lifting equipment, such as Crusher compressor and needs. Variable torque applications (such as fans and pumps) for frequency converters is sufficient. The current overload of the inverter is usually the degree of super heavy load for 2 minutes, 150%, and constantly 115% current can operate in. Heavy load [...]

Rated current: rated current at ambient temperature of reference of electrical equipment, and heating rated voltage under operating conditions when heated for a long time does not exceed the maximum current allowed to pass through. Flow has a great impact on the maximum ambient temperature is allowed to pass through. for a long time. Because the ambient temperature of the equipment installation and reference are not the same, typically are specified in the following way: electrical equipment 40°C [...]

The solution of the button control as shown in the picture below. First, the multi-function input terminal function set li1 Advanced startup, set up and set down Li3 li2 frequency the frequency (in the following image (a), then connect the control line, as shown below. KB5 SB7 Button and the start button of the control room and the field are.SB6 SB8 field and buttons, and [...]

1. Drive output frequency and the output voltage: the output of the drive frequency, is proportional to the output voltage. For example: Input 380V 50Hz, from 50Hz output frequency is set to 30Hz when the output voltage is measured 232V. Currently, the output frequency nominal frequency 60% of the input voltage, output voltage and 60% is equal to. 2. Drive output frequency and input power: output frequency of the drive, input power [...]
