SINAMICS G120C is a compact converter for control cabinet mounting in IP20 degree of protection where the Control Unit (CU) and Power Module (PM) function units are combined in one device.

The compact mechanical design and the high power density allow these devices to be installed in machine control enclosures and control cabinets for maximum space utilization. The SINAMICS G120C compact converter can be butt-mounted directly, without derating at temperatures up to 40 °C (104 °F).

SINAMICS G120C, frame size FSAA with BOP-2

SINAMICS G120C can be integrated into the widest range of applications, either using the integrated digital and analog inputs or via the integrated fieldbus interface (available in USS, Modbus RTU, PROFIBUS, PROFINET / EtherNet/IP versions). Especially the product versions with integrated PROFIBUS/PROFINET interface make full integration into the Siemens TIA family possible, therefore allowing the advantages of the seamless TIA product family to be fully utilized. SINAMICS G120C devices are preset in the factory so that they can be immediay connected to PROFIBUS and/or PROFINET fieldbus systems without parameterization.

SINAMICS G120C is also equipped with the safety function STO (Safe Torque Off) as standard, which is used to safely stop drives. As a consequence, machine manufacturers can simply comply with current machinery directives with minimum associated costs.

SINAMICS G120C can control asynchronous (induction) motors in the power range from 0.37 kW up to 132 kW (0.5 hp to 200 hp). Reliable and efficient motor operation is achieved by using state-of-the-art IGBT technology combined with vector control. The extensive range of functions integrated in the SINAMICS G120C also offers a high degree of protection for the converter and motor.

Line-side components

Line reactors

Line reactors smooth the current drawn by the converter and thus reduce harmonic components in the line current. Through the reduction of the current harmonics, the thermal load on the power components in the rectifier and in the DC-link capacitors is reduced as well as the harmonic effects on the supply. The use of a line reactor increases the service life of the converter.

Recommended line-side power components

Standard fuses can be used for the SINAMICS G120C. These must be dimensioned to comply with local regulations. In this chapter, you will find recommended components such as fuses and circuit breakers in compliance with IEC and UL regulations.

DC link components

Braking resistors

Excess energy in the DC link is dissipated in the braking resistor. The braking resistors are designed for use with the SINAMICS G120C. This has an integrated braking chopper (electronic switch).

Load-side power components

Output reactors

Output reactors reduce the rate of voltage rise (dv/dt) and the height of the current peaks, and enable longer motor cables to be connected.

Supplementary system components

Inligent Operator Panel IOP

Graphics-based, user-friendly and powerful operator panel for commissioning and diagnostics as well as local operator control and monitoring of SINAMICS G120C.

Basic Operator Panel BOP-2

A 2-line display to provide support when commissioning and troubleshooting the drive. The drive can be locally controlled.

Memory card

The parameter settings for an inverter can be stored on the SINAMICS SD memory card. When service is required, e.g. after the inverter has been replaced and the data have been downloaded from the memory card the drive system is immediay ready for use again. The associated memory card holder is integrated in the inverter.

PC inverter connection kit 2

For controlling and commissioning an inverter directly from a PC if the STARTER commissioning tool or SINAMICS Startdrive has been installed on the PC.

Spare parts

Shield plates

A set of shield plates is included in the scope of delivery for the motor and signal cables corresponding to the frame size of the SINAMICS G120C, and can also be ordered as spare parts.

Spare parts kit

This kit comprises four I/O terminals, one RS485 terminal, two pairs of Control Unit doors (1 × PN and 1 × other communication versions) and one blanking cover.

Set of connectors

A set of connectors for the line feeder cable, braking resistor and motor cable can be ordered corresponding to the frame size of the SINAMICS G120C inverter.

Roof-mounted fan

A roof-mounted fan (at the top of the device) comprising a pre-assembled unit with holder and fan can be ordered corresponding to the frame size of the SINAMICS G120C.

Fan unit

A replacement fan (at the rear of the device; heat sink) comprising a pre-assembled unit with holder and fan can be ordered corresponding to the frame size of the SINAMICS G120C.

PLC在拉力試驗系統(tǒng)中的應(yīng)用

　　1引言

　　為了煤礦生產(chǎn)的安全性，用于煤礦斜井提升設(shè)備中的絞車底盤及三環(huán)鏈等設(shè)備，均需要進(jìn)行檢驗，通過后方可允許批量生產(chǎn)和使用。而傳統(tǒng)的檢驗設(shè)備，無論在控制方式上，還是在檢驗手段上，均較落后，檢驗效率較低，而且設(shè)備的故障率也較高。因此，現(xiàn)有檢驗設(shè)備的改造問題，是目前國內(nèi)各個檢驗中心急需進(jìn)行的主要任務(wù)之一。

　　2檢驗原理及硬件系統(tǒng)設(shè)計

　　用于煤礦斜井提升的絞車、三環(huán)鏈等設(shè)備。在批量生產(chǎn)前，必須到的檢驗中心進(jìn)行性能指標(biāo)的檢測，主要測試其抗拉強(qiáng)度等性能指標(biāo)，測出其zui小拉斷拉力，并與其承載量相對應(yīng)的國家規(guī)定標(biāo)準(zhǔn)進(jìn)行比較。當(dāng)其zui小拉斷拉力大于標(biāo)準(zhǔn)所規(guī)定的允許抗拉強(qiáng)度時，則可判定該產(chǎn)品的抗拉強(qiáng)度滿足要求。

　　對上述設(shè)備進(jìn)行檢驗的PLC控制系統(tǒng)的組成框圖如圖1所示，由觸摸屏、PLC傳感器、控制按鈕、控制設(shè)備及運(yùn)行狀態(tài)指示等部分組成。

　　觸摸屏主要用于完成被檢設(shè)備的信息輸人、設(shè)備的啟?？刂?、測得的拉力數(shù)值的顯示輸出以及其他相關(guān)信息的輸出;傳感器將測得的拉力信號經(jīng)A/D轉(zhuǎn)換后送入PLC，在PLC內(nèi)部進(jìn)行相應(yīng)的運(yùn)算后，送到觸摸屏進(jìn)行顯示;PLC是控制系統(tǒng)的核心，主要用于接收觸摸屏輸人的相關(guān)信息及控制指令，輸出相應(yīng)的控制命令，同時經(jīng)A/D轉(zhuǎn)換器讀取拉力傳感器測得的數(shù)據(jù)。本系統(tǒng)中PLC選用松下電工的F印型PLC，觸摸屏選用GT一10型單色顯示觸摸屏。PLC的資源分配如表1所示。

3軟件設(shè)計

　　控制程序流程圖如圖2所示。其中對拉力值的處理是主要應(yīng)注意的問題。PLC讀取測得的拉力值，在試驗過程中，拉力值將逐漸增加，當(dāng)拉斷的瞬間，拉力值將立即減小。根據(jù)這個拉力值的變化，PLC可判斷試件是否拉斷。因此，PLC在每次讀取測得的拉力后，應(yīng)將拉力值保存在一個特定的單元內(nèi)，下一次讀取的值與所存的值進(jìn)行比較。如果當(dāng)前值小于存儲值，則可斷定試件已拉斷，存儲值為拉斷拉力。若當(dāng)前值大于存儲值，則用當(dāng)前值替換存儲值，并進(jìn)行下一次檢測，直到拉斷為止。系統(tǒng)拉力檢測梯形圖如圖3所示。其中DTloo為經(jīng)A/D轉(zhuǎn)換后所得的拉力數(shù)值，D功單元用于存儲暫存數(shù)值，DTloo單元用于存儲拉斷拉力值。
