SINAMICS G120C, frame sizes FSAA to FSF, with Inligent Operator Panel IOP
SINAMICS G120C compact inverters offer a well-balanced combination of features to address a wide range of applications. They are compact, rugged devices that are easy to operate and can be optionally equipped with a basic or advanced operator panel.
SINAMICS G120C inverters are especially suitable when it comes to meeting the requirements of system integrators, OEMs and distributors regarding high productivity and tailored performance.
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.

1 引言
PLC在机械制造的设备控制中应用非常广泛，但在普通车床数控化改造中，用PLC作数控系统的核心部件还是一个新的课题。随着PLC技术、功能不断完善，这将是一种发展趋势。本文对此加以讨论。
2 车床的PLC数控系统控制原理设计
2.1 车床的操作要求
车床一般加工回转表面、螺纹等。 要求其动作一般是X、Z向快进、工进、快退。加工过程中能进行自动、手动、车外圆与车螺纹等转换;并且能进行单步操作。
2.2 PLC数控系统需解决的问题
车床的操作过程比较复杂，而PLC一般只适用于动作的顺序控制。要将PLC用于控制车床动作，必须解决三个问题：
图1 数控系统原理图
1)如何产生驱动伺服机构的信号及X、Z向动作的协调;
2)如何改变进给系统速度;
3)车螺纹如何实现内传动及螺纹导程的变化。
将PLC及其控制模块和相应的执行元件组合，这些问题是可以解决的。
2.3 数控系统的控制原理
普通车床数控化改造工作就是将刀架、X、Z向进给改为数控控制。根据改造特点，伺服元件采用步进电机，实行开环控制系统就能满足要求。Z向脉冲当量取0.01mm，X向脉冲当量取0.005mm。选用晶体管输出型的PLC。驱动步进电机脉冲信号由编程产生，通过程序产生不同频率脉冲实现变速。X、Z向动作可通过输入手动操作或程序自动控制。车螺纹的脉冲信号由主轴脉冲发生器产生，通过与门电路接入PLC输入端，经PLC程序变频得到所需导程的脉冲。刀架转位、车刀进、退可由手动或自动程序控制。图1为数控系统原理图。
3 PLC输入、输出(I/O)点数确定
所设计的车床操作为：起点总停、Z、X向快进、工进、快退;刀架正、反转;手动、自动、单步、车螺纹转换。因此，输入需14点。根据图1得输出需9点。I/O连接图如图2所示(以三菱F1S-30MT)为例。
图2 I/O连接图
4 驱动程序(梯形图)设计
4.1 总程序结构设计
手动、自动、单步、车螺纹程序的选择采用跳转指令实现。图3是总程序结构框图。若合上X12(X13、X14、X15断开)，其常闭断开，执行手动程序;若X12断开，X13全上，程序跳过手动程序，指针到P0处，执行自动程序。
图3 总程序框图
4.2 手动程序梯形图设计
手动程序、自动程序需根据具体零件设计，这里仅以Z向快进、工进、快退的动作为例加以说明。其梯形图如图4所示。
图4 Z向手动程序梯形图
在执行手动程序状态下，按X0，Y1接通，作好起动准备。按X2，辅助继电器M0接通。通过T63计时及Y2触点组合，产生频率为103/2i的脉冲信号(i为计时时间，根据需要设定，单位为ms)，驱动Z向快进。当按下X3时(M0断开)，M1接通，M1与定时器T32组合使Y2产生频率为103/2j的脉冲(j>i)，由Y2输出，实现工进。按下X4时，M0、Y3同时接通，电机快速反转，实现快退。限于篇幅，其它程序梯形图略。[2]
