Siemens SINAMICS V20 inverter serialization (1)-selection

SINAMICS V20 series inverters are basic inverters for small-scale automated production lines launched by Siemens. They can be used with Siemens S7 series PLCs (S7-200 Smart, S7-1200/1500) used together. Founderchip (founderchip) will serialize SINAMICS V20 is introduced. In today’s article, let’s first introduce SINAMICS Selection of V20 inverter

Encoder|Transmitter|Soft starter|Power supply|VFD|Light curtain|Servo products|Human-machine interface|Solenoid valve|Cylinder|Actuator|Flow meter|Transformer|Thyristor|Sensor|Deceleration drive gearbox reducer|Linear guide|Circuit breaker|Refrigeration compressorAll industrial products of okplazas are purchased from the original factory or formal channels of agents to ensure the original authenticity, which perfectly solves the problem of industrial product sample procurement and small-batch procurement for the majority of engineers and purchasing personnel.

Divided from the appearance size, SINAMICS V20 includes: FSA, FSB, FSC, FSD, FSE five products (FS is the abbreviation of "Frame Size", that is, "external size"), among them, FSA also includes FSA-A, FSA -B and FSA-C three sub-series, inverters of different sizes have different power sizes. The following table is the specific size data, which can be used as a reference when designing the electrical cabinet:

Encoder|Transmitter|Soft starter|Power supply|VFD|Light curtain|Servo products|Human-machine interface|Solenoid valve|Cylinder|Actuator|Flow meter|Transformer|Thyristor|Sensor|Deceleration drive gearbox reducer|Linear guide|Circuit breaker|Refrigeration compressorAll industrial products of okplazas are purchased from the original factory or formal channels of agents to ensure the original authenticity, which perfectly solves the problem of industrial product sample procurement and small-batch procurement for the majority of engineers and purchasing personnel.

Divided from the type of supply voltage, SINAMICSV20 includes two voltage types: single-phase 230V AC and three-phase 400VAC.

The FSA-A and FSAB models of single-phase 230V AC inverters do not have a cooling fan; the FSA-C, FSB and FSC inverters have a cooling fan; the rated power and current of inverters of different sizes are shown in the following table:

The rated power and current of different sizes of three-phase 400V AC inverters are shown in the following table:

Encoder|Transmitter|Soft starter|Power supply|VFD|Light curtain|Servo products|Human-machine interface|Solenoid valve|Cylinder|Actuator|Flow meter|Transformer|Thyristor|Sensor|Deceleration drive gearbox reducer|Linear guide|Circuit breaker|Refrigeration compressorAll industrial products of okplazas are purchased from the original factory or formal channels of agents to ensure the original authenticity, which perfectly solves the problem of industrial product sample procurement and small-batch procurement for the majority of engineers and purchasing personnel.

The nameplate of the SINAICS V20 frequency converter contains the order number and serial number of the product. The supply voltage, power and built-in filter type of the inverter can be seen from the order number.

Take the following nameplate as an example:

Encoder|Transmitter|Soft starter|Power supply|VFD|Light curtain|Servo products|Human-machine interface|Solenoid valve|Cylinder|Actuator|Flow meter|Transformer|Thyristor|Sensor|Deceleration drive gearbox reducer|Linear guide|Circuit breaker|Refrigeration compressorAll industrial products of okplazas are purchased from the original factory or formal channels of agents to ensure the original authenticity, which perfectly solves the problem of industrial product sample procurement and small-batch procurement for the majority of engineers and purchasing personnel.

The order number is: 6SL3210-5BE25-5CV0.

Sort the letters in the order number from left to right, mark the number of digits on it, and get the following picture:

Encoder|Transmitter|Soft starter|Power supply|VFD|Light curtain|Servo products|Human-machine interface|Solenoid valve|Cylinder|Actuator|Flow meter|Transformer|Thyristor|Sensor|Deceleration drive gearbox reducer|Linear guide|Circuit breaker|Refrigeration compressorAll industrial products of okplazas are purchased from the original factory or formal channels of agents to ensure the original authenticity, which perfectly solves the problem of industrial product sample procurement and small-batch procurement for the majority of engineers and purchasing personnel.

Let's take a look at the information it contains: No. 1~9: "6SL3210-5B" is the family name of SINAMICS V20;

10th bit: Indicates the type of power supply voltage of the inverter. E-means three-phase 400V power supply; B means single-phase 230V power supply;

The 11th bit: represents the power of 10, used to calculate the power;

12th place: the tens digit of power;

13th digit: the single digit of power;

The power of the inverter is calculated according to the following formula: Assuming:

The 11th bit = n;

12th place = x;

13th place=y;

then:

Inverter power = (x*10 +y)/1000 * 10^n, unit: KW;

Note: 10^n means 10 to the nth power;

Take the nameplate above as an example:

x=5,y=5,n=2;

The power of the inverter = (5*10+5)/1000*10^2=55/1000*100=5.5 KW

Bit 14: Indicates the type of built-in filter.

A: means A type filter; C: means C3 type filter; U: means no filter;

The 15th to 16th digits: the version number, currently all "V0";

Well, the selection of the SINAMICS V20 inverter will be introduced here first, and the following articles will introduce the components, wiring, and debugging of the V20.
