步进马达与伺服马达区分讲解

步进马达与伺服马达区分在定位系统中, 最常用的马达不外乎是步进马达和伺服马达, 其中, 步进马达主要可分为2相、5相、微步进系统, 伺服马达则主要分为DC伺服和AC伺服两种 .2相、5相和微步进系统主要是驱动器所表现出来分辨率不同, 2相步进系统马达每转最细可分为400 格, 五相则为1000 格, 微步进则可从200 ~ 50000(或以上)格, 表现出来的特性以微步进最好, 加减速时间较短, 动态惯性较低.AC 和DC 伺服马达主要的分别为DC伺服比AC伺服马达多了一个碳刷, 会有维护上的问题, 而AC 伺服马达因没有碳刷, 所以后续并不会有太大维护上的问题. 所以基本上来说AC伺服系统是较DC伺服系统为优, 但DC 伺服系统主要的优势则是价位上比AC 伺服系统较便宜. 而此两种系统的控制精度皆为相同.步进系统与伺服系统主要的特点如下:.上图为标准的步进系统(开回路)上图为脉波命令式伺服系统(半闭回路)上图为电压命令式伺服系统(全闭回路)微步进驱动技术图一(全步进,两相激磁)图二(半步进)步进驱动器脉波输入方式为何有1P(one pulse) 及2P(two pulse)之分?1. TWO pulse 方式, 亦即所谓的2P方式.所谓的TWO pulse方式,一般日系进口的定位控制器或步进驱动器皆采此种脉波格式,就是由控制器输出到步进马达驱动器的两个信号中,一个是正转脉波(CW)信号,用来输出正转方向所要移动脉波数量,另一个信号则为反转方向(CCW)信号,用来输出反转方向所要移动脉波数量,以此来控制步进马达作正反转的任意长度移动了. 此两个信号的波形如下:这种脉波输出方式会有两种不良的影响,其一,会有冲突的情况,因为若是两边因某些原因而都有输出脉波信号到驱动器,则无法确定到底驱动器是要正转还是要反转;其二,因为两边都有可能输出脉波到驱动器,若在速度变高,高频的信号较容易受到外在的干扰,所以此两个脉波信号受干扰的机率会比较大,但TWO pulse的方式,若是要让马达的转动方向颠倒,只要将此两个脉波信号互换即可,程序比较方便.2. ONE pulse方式, 也就是所谓的1P方式.所谓的ONE pulse方式,一般欧美进口的定位控制器或步进驱动器皆采此种脉波格式,就是由控制器输出到步进马达驱动器的两个信号中,有一个是脉波(pulse或step)信号,用来输出所要移动脉波数量(即长度),另一个信号为方向(direction)信号,这信号只是做信号高低准位的切换而已,用来表示马达的转动方向,如此一来,即可控制步进马达作正反转的任意长度移动了. 此两个信号的波形如下:这种脉波输出方式比TWO pulse较好,因为不会有像TWO pulse一样可能会有冲突的情形发生,且这种ONE pulse方式的受干扰可能性较TWO pulse小,因为只有一条信号有可能是高频的脉波信号(pulse),另一个方向信号(dir)则只是有时会有准位上的变化,并非高频信号,所以较不容易受到干扰,ONE pulse方式主要的缺点是若要使马达方向颠倒,不像TWO pulse方式那样方便, 而需在马达线那端互换接线来成方向颠倒的功能.。

a4982中文资料

基于A4982设计的DMOS微型步进马达驱动技术Allegro公司的A4982是集成了电平转换和过流保护的微型步进马达驱动器,适用于双极步进马达驱动,工作在全步进,半步进,1/4步进和1/6步进模式,输出驱动能力高达35V和±2 A. A4982包括固定的离线电流调节器,兼容3.3V和5V逻辑,睡眠模式电流小于10 μA.本文介绍了A4982主要特性和优势, 功能方框图, 典型应用框图以及LP和ET封装的应用电路和PCB布局框图.DMOS Microstepping Driver with Translator and Overcurrent ProtectionThe A4982 is a complete microstepping motor driver with built-in translator for easy operation. It is designed to operate bipolar stepper motors in full-,half-, quarter-, and sixteenth-step modes, with an output drive capacity of up to 35 V and ±2 A.The A4982 includes a fixed off-time current regulator which has the ability to operate in Slow or Mixed decay modes. The ET package meets customer requirements for no smoke no fire (NSNF) designs by adding no-connect pins between critical output, sense, and supply pins. So, in the case of a pin-to-adjacent-pin short, the device does not cause smoke or fire. Additionally, the device does not cause smoke or fire when any pin is shorted to ground or left open.The translator is the key to the easy implementation of the A4982. Simply inputting one pulse on the STEP input drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program.The A4982 interface is an ideal fit for applications where a complex microprocessor is unavailable or is overburdened. During stepping operation, the chopping control in the A4982 automatically selects the current decay mode, Slow or Mixed. In Mixed decay mode, the device is set initially to a fast decay for a proportion of the fixed off-time, then to a slow decay for the remainder of the off-time. Mixed decay current control results in reduced audible motor noise, increased step accuracy, and reduced power dissipation.Internal synchronous rectification control circuitry is provided to improve power dissipation during PWM operation. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection.Special power-on sequencing is not required. The A4982 is supplied in two surface mount package, the ET, a 5 mm × 5 mm, 0.90 mm nominal overall package height QFN package, and the LP package, a 24-pin TSSOP. Both packages have exposed pads for enhanced thermal dissipation, and are lead (Pb) free (suffix –T), with 100% matte tin plated leadframes.A4982主要特性和优势:▪ Low RDS(ON) outputs▪ Automatic current decay mode detection/selection▪ Mixed and Slow current decay modes▪ Synchronous rectification for low power dissipation ▪ Internal UVLO▪ Crossover-current protection▪ 3.3 and 5 V compatible logic supply▪ Thin profile QFN and TSSOP packages▪ Thermal shutdown circuitry▪ Short-to-ground protection▪ Shorted load protection▪ L ow current Sleep mode, < 10 μA▪ No smoke no fire (NSNF) compliance (ET package)图1.A4982功能方框图图2.A4982典型应用框图图3.A4982 LP封装应用电路和PCB布局框图图4.A4982 ET封装应用电路和PCB布局框图A4982 是一款完全的微步电动机驱动器，带有内置转换器，易于操作。

描述 DP4985是一种便于使用的内部集成了译码器的微步进电机驱动器。其设计为使双极步进电机能够以全、半、 1/4和1/8步进操作。步进模式由逻辑输入MSx选择。输出驱动能力达到35V和±1A。 DP4985包括一个能够控制慢或混合衰减模式的电流调节器，其截止时间固定。译码器是DP4985易于实施的关键。通过STEP简单的输入一个脉冲就可以使电机完成一次步进，省去了相序表，高频控制线及复杂的编程接口。这使其更适于应用在没有复杂的微处理器或微处理器负担过重的场合。在步进操作期间，DP4985的内部电路可以自动的控制其PWM操作工作在快、慢及混合衰减模式。在混合衰减模式下，器件初始经过一段时间的快衰减后，将切换至慢衰减模式直至固定截止时间结束。混合衰减模式控制不但降低了电机工作时产生的噪声，还增加了步进的准确性，同时减小了系统的功耗。内部的同步整流控制电路改善了PWM操作时的功耗。内部保护电路包括：利用迟滞实现的过热关机、欠压锁定及交叉电流保护。不需要特别的加电排序。 DP4985目前提供一种贴片封装：带有裸露焊盘的 QFN-24封装，能有效改善散热性能，且是无铅产品，引脚框采用100％雾锡电镀。型号选择

A4980KLPTR-T;中文规格书,Datasheet资料

DescriptionThe A 4980 is a flexible microstepping motor driver with built-in translator for easy operation. It is a single-chip solution, designed to operate bipolar stepper motors in full-, half-, quarter- and sixteenth-step modes, at up to 28 V and ±1.4 A. The A4980 can be controlled by simple Step and Direction inputs, or through the SPI-compatible serial interface that also can be used to program many of the integrated features and to read diagnostic information.The current regulator can be programmed to operate in fixed off-time or fixed frequency PWM, with several decay modes to reduce audible motor noise and increase step accuracy. In addition the phase current tables can be programmed via the serial interface to create unique microstep current profiles to further improve motor performance for specific applications.The current in each phase of the motor is controlled through a DMOS full bridge, using synchronous rectification to improve power dissipation. Internal circuits and timers prevent cross-conduction and shoot-through, when switching between high-side and low-side drives.The outputs are protected from short circuits, and features for low load current and stalled rotor detection are included. Chip-level protection includes: hot and cold thermal warnings, overtemperature shutdown, and overvoltage and undervoltage lockout.The A4980 is supplied in a 28-pin TSSOP power package with an exposed thermal pad (package type LP). This package is lead (Pb) free with 100% matte-tin leadframe plating.Features and Benefits• Peak motor current up to ±1.4 A, 28 V• Low R DS(on) outputs, 0.5 Ω source and sink, typical • Automatic current decay mode detection/selection • Mixed, Fast, and Slow current decay modes• Synchronous rectification for low power dissipation• Internal OVLO, UVLO, and Thermal Shutdown circuitry • Crossover-current protection• Short circuit, and open load diagnostics • Hot and cold thermal warning • Stall detect features• SPI-compatible or simple Step and Direction motion control • Highly configurable via SPI-compatible serial interfaceApplications• Automotive stepper motors • Engine management • Headlamp positioningAutomotive, Programmable Stepper DriverPackage: 28-pin TSSOP with exposed thermal pad (suffix LP)Typical ApplicationsNot to scaleA4980AutomotiveLogicAutomotive LogicSelection GuidePart Number Packing*A4980KLP-T50 pieces per tube 4.4 mm × 9.7 mm, 1.2 mm nominal heightTSSOP with exposed thermal pad A4980KLPTR-T4000 pieces per reel*Contact Allegro® for additional packing optionsAbsolute Maximum Ratings With respect to GNDCharacteristic Symbol Notes Rating Unit Load Supply Voltage V BBx Applies to V BBA and V BBB–0.3 to 50V Logic Supply Voltage V DD–0.3 to 6V Pin CP1–0.3 to V BB V Pins CP2, VCP–0.3 to V BB+8V Pins STEP, DIR, ENABLE, DIAG–0.3 to 6V Pin VREG–0.3 to 8.5V Pin RESETn Can be pulled to V BB with 38 kΩ–0.3 to 6V Pin OSC–0.3 to 6V Pins MS0, MS1–0.3 to 6V Pins SDI, SDO, SCK, STRn–0.3 to 6V Pin REF–0.3 to 6V Pins OAP, OAM, OBP, OBM–0.3 to V BB V Pins SENSA, SENSB–0.3 to 1V Ambient Operating TemperatureRangeT A Range K;

It is also suitable for other low current stepper applications such as air con-ditioning and venting. It provides a highly flexible microstepping motor driver that can be configured via the SPI-compatible serial interface. It can be controlled with simple Step and Direction inputs, for high speed stepping applications, or directly through the serial interface by writing a step change value.The two DMOS full bridges are capable of driving bipolar step-per motors in full-, half-, quarter-, eighth- and sixteenth-step modes, at up to 28 V and ±1.4 A. The current in each phase of the stepper motor is regulated by a peak detect PWM current control scheme that can be programmed to operate in fixed off-time or fixed frequency. Several decay modes can be selected to reduce audible motor noise and increase step accuracy. In addition the phase current tables, which default to a sinusoidal current profile, can be programmed via the serial interface to create unique microstep current profiles to further improve motor performance for specific applications.The outputs are protected from short circuits, and features for open load and stalled rotor detection are included. Chip level pro-tection includes hot and cold thermal warning, overtemperature shutdown, and overvoltage and undervoltage lockout.Pin FunctionsVBBA, VBBB Main motor supply and chip supply for internal regulators and charge pump. VBBA and VBBB should be con-nected together and each decoupled to ground with a low ESR electrolytic capacitor and a good ceramic capacitor.Note: Any reference to “VBB” in this specification is defined as applying to both VBBA and VBBB.CP1, CP2 Pump capacitor connection for charge pump. Connect a 100 nF (50 V) ceramic capacitor between CP1 and CP2.VCP Above-supply voltage for high-side drive. A 100 nF (16 V) ceramic capacitor should be connected between VCP and VBB to provide the pump storage reservoir.VDD Logic supply. Compatible with 3.3 V and 5 V logic. Should be decoupled to ground with a 100 nF (10 V) ceramic capacitor. VREG Regulated supply for bridge gate drive. Should be decou-pled to ground with a 470 nF (10 V) ceramic capacitor.AGND Analog reference ground. Quiet return for measurement and input references. Connect to PGND (see Layout section).PGND Digital and power ground. Connect to supply ground and AGND (see Layout section).OAP, OAM Motor connection for phase A. Positive motor phase current direction is defined as flowing from OAM to OAP. OBP, OBM Motor connection for phase B. Positive motor phase current direction is defined as flowing from OBM to OBP.SENSA Phase A current sense. Connect sense resistor between SENSA and PGND.SENSB Phase B current sense. Connect sense resistor between SENSB and PGND.REF Reference input to set absolute maximum current level for both phases. Defaults to internal reference when tied to VDD. STEP Step logic input. Motor advances on rising edge. Filtered input with hysteresis.DIR Direction logic input. Direction changes on the next STEP rising edge. When high, the Phase Angle Number is increased on the rising edge of STEP. Has no effect when using the serial interface. Filtered input with hysteresis.MS0 Microstep resolution select input.MS1 Microstep resolution select input.RESETn Resets faults when pulsed low. Forces low-power shut-down (sleep) when held low for more than the Reset Shutdown Width, t RSD. Can be pulled to VBB with 30 kΩ resistor. ENABLE Controls activity of bridge outputs. When held low, deactivates the outputs, that is, turns off all output bridge FETs. Internal logic continues to follow input commands.SDI Serial data input. 16-bit serial word input MSB first.SDO Serial data output. High impedance when STRn is high. Out-puts bit 15 of the diagnostic registers (Fault Register 0 and Fault Register 1), the Fault Register flag, as soon as STRn goes low. SCK Serial interface clock. Data is latched in from SDI on the rising edge of the SCK clock signal. There must be 16 rising edges per write and SCK must be held high when STRn changes. STRn Serial data strobe and serial access enable. When STRn is high any activity on SCK or SDI is ignored, and SDO is highimpedance allowing multiple SDI slaves to have common SDI, SCK, and SDO connections.DIAG Diagnostic output. Function selected via the serial inter-face, setting Configuration Register 1. Default is Fault output. OSC With bit 13 in Configuration Register 1 set to 0, either con-nect this pin to AGND to use the internal oscillator running at the default frequency of 4 MHz, or connect a resistor to VDD to set the internal oscillator frequency. (The approximate frequency is calculated from:f OSC = 10 000 / (48 R OSC – 20)where f OSC is the internal oscillator frequency in MHz, and R OSC is the value, in kΩ of the resistor between OSC and VDD.)If bit 13 in Configuration Register 1 is set to 1, then OSC is the input for an external system clock, which must have a frequency between 3 and 5 MHz. In this mode a watchdog is provided to detect loss of the system clock. If the OSC pin remains high or low for more than the watchdog time, t WD , 1 μs typical, then the Fault Register flag (bit 15 in the diagnostic registers) is set and the outputs are disabled until the clock restarts.Driving a Stepper MotorA two-phase stepper motor is made to rotate by sequencingthe relative currents in each phase. In its simplest form, each phase is simply fully energized in turn by applying a voltage to the winding. For more precise control of the motor torque over temperature and voltage ranges, current control is required. For efficiency this is usually accomplished using pulse width modula-tion (PWM) techniques. In addition current control also allows the relative current in each phase to be controlled, providing more precise control over the motor movement and hence improve-ments in torque ripple and mechanical noise. Further details of stepper motor control are provided in Appendix 1.For bipolar stepper motors the current direction is significant,so the voltage applied to each phase must be reversible. This requires the use of a full bridge (also known as an H-bridge) which can switch each phase connection to supply or to ground. Phase Current ControlIn the A4980, current to each phase of the two-phase bipolar stepper motor is controlled through a low impedance N-channel DMOS full bridge. This allows efficient and precise control of the phase current using PWM switching. The full-bridge con-figuration provides full control over the current direction during the PWM on-time, and over the current decay mode during the PWM off-time. Due to the flexibility of the A4980 these control techniques can be completely transparent to the user or can be partially- or fully-programmed through the serial interface.Each leg (high-side, low-side pair) of a bridge is protected from shoot-through by a fixed dead time. This is the time between switching off one FET and switching on the complementary FET. Cross-conduction is prevented by lock-out logic in each driver pair. The phase currents and in particular the relative phase currents are defined in the Phase Current table (table 7). This table defines the two phase currents at each microstep position. For each of the two phases, the currents are measured using a sense resistor, R S, with voltage feedback to the respective SENSx pin. The target current level is defined by the voltage from the digital-to-analog converter (DAC) for that phase. The sense voltage is amplified by a fixed gain and compared to the output of the DAC.There are two types of maximum current: the absolute maximum, I SMAX , the maximum possible current defined by the sense resis-tor and the reference input; and the phase maximum, I PMAX , the maximum current delivered to a motor phase.The absolute maximum current, I SMAX, is defined as:I SMAX = V REF / (16 × R S )where V REF is the voltage at the REF pin, and R S is the sense resistor value.The phase maximum, I PMAX, is the 100% reference level for the phase current table and may be a fraction of the absolute maxi-mum current, I SMAX, depending on the value of the MXI0 and MXI1 bits in Configuration Register 0.For example:• if R S = 180 mΩ and V REF = 2 V, then I SMAX = 694 mA• if MXI1= 1 and MXI0 = 0, then I PMAX = 520 mAThe actual current delivered to each phase at each Step Angle Number is determined by the value of I PMAX and the contentsof the Phase Current table. For each phase, the value in the table is passed to the DAC, which uses I PMAX as the reference 100% level (code 63) and reduces the current target depending on the DAC code. The output from the DAC is used as the input to the current comparators.The current comparison is ignored at the start of the PWMon-time for a duration referred to as the blank time. The blank time is necessary to prevent any capacitive switching currents from causing a peak current detection.The PWM on-time starts at the beginning of each PWM period. The current rises in the phase winding until the sense voltage reaches the required current level. At this point the PWM off-timestarts and the bridge is switched into one of two decay modes, slow decay or fast decay:• Slow decay is most effective when the current is rising from step to step. and it occurs when the phase winding is effectively shorted by switching-on either both high-side FETs or both low-side FETs in the full bridge.• Fast decay is most effective when the current is falling from step to step, and it occurs when the voltage on the phase is reversed.One disadvantage of fast decay is the increased current ripple in the phase winding. However, this can be reduced while main-taining good current control, by using a short time of fast decay followed by slow decay for the remainder of the PWM off-time. This technique is commonly referred to as mixed decay.The A4980 provides two methods to determine the PWM frequency: fixed off-time and fixed frequency. At power-up the default mode is fixed off-time. Fixed frequency can be selected through the serial interface. Fixed off-time provides a marginal improvement in current accuracy over a wide range of current levels. Fixed frequency provides a fixed fundamental frequency to allow more precise supply filtering for EMC reduction. In both cases the PWM off-time will not be present if the peak current limit is not attained during the PWM on-time.Phase Current TableThe relative phase currents are defined by the Phase Current table. This table contains 64 lines and is addressed by the Step Angle Number, where Step Angle Number 0 corresponds to 0° or 360°. The Step Angle Number is generated internally by the step sequencer, which is controlled either by the STEP and DIR inputs or by the step change value from the serial input. The Step Angle Number determines the motor position within the 360° electri-cal cycle and a sequence of Step Angle Numbers determines the motor movement. Note that there are four full mechanical steps per 360° electrical cycle.Each line of the Phase Current table (table 7) has a 6-bit value per phase to set the DAC level for that phase, plus an additional bit per phase to determine the current direction for that phase. The Step Angle Number sets the electrical angle of the stepper motor in one-sixteenth microsteps, approximately equivalent to electri-cal steps of 5.625°.On first power-up or after a VDD power-on reset, the Phase Cur-rent table values are reset to define a sinusoidal current profile and the Step Angle Number is set to 8, equivalent to the electri-cal cycle 45° position. This position is defined as the “home” position. The maximum current in each phase, I PMAX, is defined by the sense resistor and the Maximum Current setting (bitsMXI[0..1]) in Configuration Register 0. The phase currents for each entry in the Phase Current table are expressed as a percent-age of this maximum phase current.When using the STEP and DIR inputs to control the stepper motor, the A4980 automatically increases or decreases the Step Angle Number according to the step sequence associated with the selected step mode. The default step mode, reset at power-up or after a power on reset, is full step. Half-, quarter-, and sixteenth-step sequences are also available when using the STEP and DIR inputs, and are selected using the logical OR of the MS0 and MS1 inputs and the MS0 and MS1 bits in Configuration Reg-ister 0. The eighth-step sequence is shown in the Phase Current table for reference only.When using the serial interface to control the stepper motor, a step change value (6-bit) is input through the serial interfaceto increase or decrease the step angle. The step change valueis a two’s complement (2’sC) number, where a positive value increases the step angle and a negative value decreases the Step Angle Number. A single step change in the Step Angle Number is equivalent to a single one-sixteenth microstep. Therefore, for cor-rect motor movement, the step change value should be restricted to no greater than 16 steps, positive or negative.This facility enables full control of the stepper motor at any microstep resolution up to and including sixteenth-step, plusthe ability to change microstep resolution “on-the-fly” from one microstep to the next.In both control input method cases, the resulting Step Angle Number is used to determine the phase current value and current direction for each phase, based on the Phase Current table. The decay mode is determined by the position in the Phase Current table and the intended direction of rotation of the motor. DiagnosticsThe A4980 integrates a number of diagnostic features to protect the driver and load as far as possible from fault conditions and extreme operating environments. At the system level the sup-ply voltages and chip temperature are monitored. A number of these features automatically disable the current drive to protect the outputs and the load. Others only provide an indication of the likely fault status, as shown in the Fault table (table 1). A single diagnostic output pin (DIAG) can be programmed through the serial interface to provide several different internal signals. At power-up, or after a power-on-reset the DIAG pin outputs a simple Fault Output flag which will be low if a fault is present. The Fault Output flag remains low while the fault is present or if分销商库存信息: ALLEGROA4980KLPTR-T。
