Q
Does MG/ BG support wake-up diesel generators?
2021-03-31
A

No, there is no internal outpuit terminal for wake up generator.

Q
Can GD5000 be configured with PID?
2021-03-31
A

GD5000 comes standard with built-in PID regulator, which can realize closed-loop control.

Q
Does the GD3000 have a four-quadrant function?
2021-03-31
A

The full range of medium voltage GD1000/GD2000/GD3000 products can provide two-quadrant or four-quadrant products.

Q
What is the difference between GD3000/3300V and GD5000/3300V?
2021-03-24
A

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.

Q
Why the pump water flow is lower, after removed the capacitor?
2021-03-24
A

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.

Q
How many types of DA200 braking? What are they and what's the difference?
2021-03-24
A

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.

Q
What's the reason when the screen of VT HMI shows 'download: wait?
2021-03-24
A

The screen is locked tightly, please try to loose the installation screw and power on again.

Q
What should we do if the password of PLC has been forgotten?
2021-03-24
A

There is not factory password for it and can only format PLC.

Q
The extension modules can be used for different series of PLC?
2021-03-17
A

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.
