The UC5180C includes an input noise filter and is intended for applications employing data rates up to 200 KBPS. A failsafe function allows these devices to "fail" to a known state under a wide variety of fault conditions at the inputs.FEATURES•Meets EIA 232E/423A/422A and CCITT V.10,V.11, V.28, X.26, X.27•Single +5V Supply--TTL Compatible Outputs•Differential Inputs Withstand ± 25V •Low Open Circuit Voltage for Improved Failsafe Characteristic•Reduced Supply Current--35 mA Max •Input Noise Filter •Internal Hysteresis1/94DC ELECTRICAL CHARACTERISTICS:Figure 1. V tL , V tH , V H DefinitionUnless otherwise stated these specifications apply for T A = 0°C to +70°C, V CCAC ELECTRICAL CHARACTERISTICS: V CC = 5V ± 5%, T A = 0°C to + 70°C, Figure 2, T A = T J.Note 2:R S is a resistor in series with each input.Note 3:Measured after 100ms warm up (at 0°C)Note 4:Only 1 output may be shorted at one timeand then only for a maximum of 1 sec.APPLICATIONS INFORMATIONFailsafe OperationThese devices provide a failsafe operating mode to guard against input fault conditions as defined in EIA422A and EIA423A standards. These fault condi-tions are (1) drive in power-off condition, (2) receiver not interconnected with driver, (3) open-circuited intercon-necting cable, and (4) short-circuited interconnecting cable. If one of these four fault conditions occurs at the inputs of a receiver, then the output of that receiver is driven to a known logic level. The receiver is pro-grammed by connecting the failsafe input to V CC or ground. A connection to V CC provides a logic "1" output under fault conditions, while a connection to ground provides a logic "0". There are two failsafe pins (F S1and F S2) on the UC5180C where each provides com-mon failsafe control for four receivers.Input Filtering (UC5180C)The UC5180C has input filtering for additional noise re-jection. This filtering is a function of both signal level and frequency. For the specified input (5.5 MHz at ±500mV) the input stage filter attenuates the signal such that the output stage threshold levels are not exceeded and no change of state occurs at the output.EIA422A/V.11 DATA TRANSMISSIONUNITRODE INTEGRA TED CIRCUITS7 CONTINENTAL BLVD. • MERRIMACK, NH 03054TEL.

The capacitor C S is charged from 0V with a constant current of 1µA. The soft-start time for the duty cyclet S = 0.8 x C S (µF)When V SCP reaches 0.8V, the G5180 leaves the soft-start mode to enter the normal mode and enable the SCP function. If the output load conditions change rapidly causing the output to drop suddenly, the ex-ternal capacitor C S will start to charge because the error amplifier output (FB pin) is fixed at V OMax +. When the external capacitor is charged above 0.8V, the out-put pin is set low. Once the latch circuit has set, the capacitor C S will be discharged to low state and the latch circuit will not reset until power is turned off or the power supply is restarted.Short-circuit detection time (or full soft-start time):t PE = 0.8 x C S (µF)Setting Oscillating FrequencyThe oscillator circuit generates a triangular sawtooth wave with a peak of 0.8V and a trough of 0.1V using the timing capacitor (C T ) and the timing resistor (R T ) that are connected to the OSC pin. This oscillator can provide oscillating frequency in the range from 20kHz to 1MHz. The waveform of the OSC pin is shown as Figure 1.Figure 1 The cycle (T) can be determined as follows:V X V X = V H x e - t / (CTx R T )t = -C T x R T x ln (V H)()[]s R C 1.28.0/1.0ln R C T T T T T ××≈××−=Switching Regulator FunctionReference Voltage circuitA temperature-compensated reference voltage (~1.25V) is generated by the reference voltage circuit from the voltage supplied by the power supply pin (pin 3). The circuit also sets the idle period besides providing the reference voltage for the switching regulator.Error AmplifierThe error amplifier detects the output voltage of the switching regulator and sets the PWM control signal. The voltage gain is fixed. The system is made stable by connecting a phase compensation capacitor to the FB pin (pin 8).PWM ComparatorThe voltage comparator includes one inverting and three non-inverting inputs. The comparator is a voltage to pulse width converter that controls the ON time of the output pulse depending on the level of input volt-age. The output level remains high when the sawtooth wave is lower than the error amplifier output voltage, the soft start setting voltage, and the idle period setting voltage.Output CircuitThe output circuit can drive an external NPN transistor or NMOS directly. The value of the ON/OFF current can be set by a resistor connected to the BR/CTL pin (pin 4). Stand-by mode (supply current 1µA or less) can be set by connecting the BR/CTL pin (pin 4) to V CC or by making the pin open.Under-Voltage Lockout (UVLO)Transients during powering on or instantaneous glitches in the supply voltage can cause the control IC to malfunction and damage the system. To prevent malfunction at low input voltage, the circuit compares the supply voltage to the internal reference voltage to detect a low input voltage. Once detected, the circuit sets the output pin low.V O S C V HV XV LT im ePackage InformationSOP-8 PackageNote:1. Package body sizes exclude mold flash and gate burrs2.

CW6180C卧式车床说明书【范本模板】

CW6180C卧式车床说明书车床是机床中应用最广泛的一种，它可以用于切削各种工件的外圆、内孔、端面及螺纹.车床在加工工件时，随着工件材料和材质的不同，应选择合适的主轴转速及进给速度.但目前中小型车床多采用不变速的异步电动机拖动，它的变速是靠齿轮箱的有级调速来实现的，所以它的控制电路比较简单。

为满足加工的需要,主轴的旋转运动有时需要正转或反转，这个要求一般是通过改变主轴电动机的转向或采用离合器来实现的.进给运动多半是把主轴运动分出一部分动力，通过挂轮箱传给进给箱来实现刀具的进给。

有的为了提高效率，刀架的快速运动由一台进给电动机单独拖动。

车床一般都设有交流电动机拖动的冷却泵,来实现刀具切削时冷却。

有的还专设一台润滑泵对系统进行润滑。

一、机床的主要结构和运动形式卧式车床的电气控制车床的种类很多，其中卧式车床是应用极为广泛的金属切削机床。

它用于对具有旋转表面的工件进行加工，如车削外圆、内圆、端面、螺纹等，也可用钻头、铰刀、镗刀等刀具进行加工.1、卧式车床的主要结构卧式车床的结构外形如图3—1所示。

它主要由床身10、主轴变速箱3、挂轮箱2、进给箱1、溜板箱6、刀架5、尾座7、光杆9与丝杠8等部分构成。

图3-1卧式车床的外形结构示意图1一进给箱；2一挂轮箱；3一主轴变速箱;4一卡盘；5一刀架；6一溜板箱;卜尾座；8一丝杠;9一光杆；2、卧式车床的主要运动车床的切削加工包括主运动、进给运动和辅助运动。

主运动为工件的旋转运动，由主轴通过卡盘或顶尖带动工件旋转。

进给运动为刀具的直线运动,由进给箱调节加工时的纵向或横向进给量。

辅助运动为刀架的快速移动及工件的夹紧、放松等.二、车床对电气控制的要求主要控制电器为三台电机：主电动机、冷却泵电机、快速移动电机。

三台电机都要有短路保护措施。

信号说明如表1所示。

主电动机和冷却泵电机采用热继电器进行过载保护；主电动机要采用降压起动方式起动；主电动机要求能够正反转控制，并且有点动调整控制和长动控制，采用反接制动；主回路负载的电流大小能够监控，但要防止启动电流对电流表产生冲击；机床要有照明设施。
