What does the reservation in the Siemens G120 subscript mean?

Like Siemens, the meaning of the subscript is reserved, and it is planned that this product is not a qualified product, and this reserved product should be accidentally sent over, and you will find such a manufacturer.

1.If you have any questions like this, you can go to the G120 section of the Siemens Industry Forum, where you will be answered by a number of relevant drive experts.

w phase overcurrent.

Inverter action: off 2

Possible cause: -w phase overcurrent tripping.

Ground fault. Solution: Check the wiring of the inverter and motor.

The solution given by the fault code is to troubleshoot the wiring problem, you had better take a picture of the wiring, and then ask questions on the Siemens Industry Forum in order to better troubleshoot the cause of the fault.

Don't you know Siemens? What does the reservation in 20 subscript mean? Well, this general has to be checked on the Internet, carefully ask and call ** for after-sales service, you can know what it means.

In this case, it must be in his maintenance or later maintenance, and he must look at his thing, so he can achieve a very good effect.

There are still a lot of things kept in the Siemens subscript, and you can check the content on the Internet.

You can adjust the deceleration time of the inverter to 0, this has to go to the inverter parameter comparison table to find it, and I can't remember which parameter it is.

You should check some news about Siemens Electric on the Internet, or pay attention to his ** or something, and listen to his professional team to explain it to you.

The reservation in the Siemens G120 subscript is meaningful.

It's that you slow down too fast to activate the DC bus voltage controller due to exceeding the upper limit of the turn-on threshold (R1242, R1282).

The ramp descent time is automatically increased to keep the DC bus voltage (R0070) within the allowable limit value. There is control between the set speed and the actual speed.

system deviation. Therefore, when the DC bus voltage controller is disconnected, the output of the boot encoder is set to the speed list value.

Monitoring configuration (v f)).

Processing: If you don't want the controller to have an effect:

Increases ramp descent time.

Disconnect the VDC Max Controller (set P1240 = 0 in Vector Control; Set p1280 = 0 in V f control).

Use a clipper or feedback unit.

A07401 (N) Driver: Maximum DC bus voltage controller.

A word is two bytes (one byte is 8 bits), a total of 16 bits, each bit represents a different function, and the 0 and 1 of each bit indicate the different states of the function. Using this word to control the state of the inverter is the state control word. I don't know if you can understand if you say that.

Is there a host computer communicating with the inverter? This alarm means that the inverter cannot detect the periodic communication with the host computer.

The motor temperature exceeds the fault threshold (P0605) or the delay segment (P0606) expires after the alarm threshold (P0604) is exceeded. Execute the reaction set in P0610. The alarm is revoked when the operating threshold for disconnection monitoring is exceeded or when no sensor is connected (r > 2120 ohm).

The simplest difference, the G120 belongs to the universal inverter, which is an upgraded version of the 440, and the S120 can be used for motion control and speed control. **Poor big, S120 expensive,

One is a general-purpose inverter and the other is a dedicated inverter. The general purpose is large in size and high in price.

In fact, there is not such a big definition, sometimes the same responsibility can be used, but it is just a matter of technical parameters.

Siemens S120 series I have 380v630 kW in stock here.

One is the inverter with more servo control behind it.

SINAMICS G120 - General type ordinary inverter, G means General.

The G120 inverter is an integrated inverter, which combines the rectifier and inverter units together, and you don't have to make a separate selection. However, the G120 has limited capabilities, and it has at most vector axes for vector control. And the rectifier part is non-reciprocal.

SINAMICS S120 - Special type general inverter, S means SPECIAL.

The S120 inverter is a rectifier and inverter unit separate inverter, which can be selected and configured separately for rectifier and inverter units. The S120 is very powerful, it can not only have a vector axis, but also a servo axis, and the rectifier part has a variety of options such as non-feedback, feedback, active front end, etc.

SINAMICS S120 is a high-performance, high-precision frequency converter. The hardware has a modular structural design, which is simple and easy to install and maintain; Powerful software features make it suitable for a wide range of complex applications. It can not only do servo control, but also do vector control, can realize speed control, torque control, position control and other control methods, and can meet the requirements of motion control; A variety of cooling methods make it suitable for various occasions and applications.

Torque. The inverter cannot actively control the output torque, and can only output the corresponding torque according to the size of the load demand. For example, if you have 100kg of power, but the force you can emit is related to the weight of the object you lift, if the weight of the object is 10kg, you can only use 10kg of force.
