The full range of medium voltage GD1000/GD2000/GD3000 products can provide two-quadrant or four-quadrant products.
GD5000/3300V products are designed with multi-level power units connected in series. GD3000/3300V adopts a three-level topology design scheme, mainly comparing and replacing ABB ACS1000 series and Siemens GM150 series.
As the single-phase motor contains the starting capacitor, the start-up capacitor is designed to generate a 90-degree phase difference between the primary and secondary windings of the single-phase motor, resulting in a rotating magnetic field to rotate the motor. The size of the starting capacitor is generally designed according to the frequency 50Hz, but when the single-phase motor frequency control, the frequency will not always work at 50Hz, it is difficult to produce rotating magnetic field, the common method is to remove the single-phase motor start and run Capacitor, the use of two-phase control method.
After adopt the method of removing the capacitor, the software algorithm improvements, it is necessary to ensure that limit the starting current, but also to ensure that the starting torque, so the final output voltage than the direct start voltage amplitude is low, resulting in load capacity decreased.
It mainly has two type of brake type which are permanent magnetic brake and eletro-magnetic brake. For permanent magnetic brake, the heating is small, accuracy is high, no noise but it's expensive; For electro-magnetic brake, the heating is big, accuracy is low, it has noise but it's cheap.
The screen is locked tightly, please try to loose the installation screw and power on again.
There is not factory password for it and can only format PLC.
The extension modules of IVC1L can be used in IVC1, just the height of IVC1L extension modules is about 1cm higher than the ones of IVC1. The extension modules of IVC2 is same with IVC3. IVC2L has isolated extension modules, cannot be used in other series PLC.
It can provide variable frequency control and power frequency control. Variable frequency control requires a corresponding power VFD to control the cooling fan; power frequency control uses the GD300-1A relay output to control the start and stop of the fan. The start and stop temperature of the fan can be set on the HMI.
The overload capacity of the GD300-21 main motor is 150% for 1 minute and 120% can run continuously. The fan motor overload capacity is 120% for 1 minute.
