I OUT = (1.5 V / 5) / 0.3 Ω = 1.0 A(3) Chip enable terminal/ VCC functionWhen Chip enable terminal/ V CC pin is at low levels, the IC enters stand-by mode, all logic is reset and outputis turned OFF.When Chip enable terminal/ V CC pin is at high levels, the stand-by mode is released(4) Step pin function(5) Forward / reverse switching functionCW/CCW OperationL CW H CCW(6) Output enable functionWhen the ENABLE pin is set Low, the output is forced OFF and goes to high impedance. However, the internallogic circuits are operating, so the excitation position proceeds when the CLK is input. Therefore, when ENABLE pin is returned to High, the output level conforms to the excitation position proceeded by the CLK input.(7) DECAY modeThe DECAY mode of the output current becomes only MIXED DECAY.(8) Chopping frequency setting functionChopping frequency is set as shown below by a capacitor between OSC1 pin and GND.Fch = 1 ／(C1+20pF／10×10-6) (Hz)(Example) When Cosc1=100pF, the chopping frequency is shown below.Fch = 1 ／((20+ 100)×10-12／10×10-6) (Hz)=83.3（kHz）Note・The 20pF is a stray capacitance which is involved by the package of THB7128-E.(9) Output short-circuit protection circuitBuild-in output short-circuit protection circuit makes output to enter in stand-by mode. This function prevents the IC from damaging when the output shorts circuit by a voltage short or a ground short, etc. When output short state is detected, short-circuit detection circuit starts the operating and output is once turned OFF. After the timer latch time (typ: 256µs), output is turned ON again. Still the output is at short state, the output is turned OFF and fixed instand-by mode.When output is fixed in stand-by mode by output short protection circuit, output is released the latch by setting Chip enable terminal/ V CC="L"(10) Output current tolerance/cn/(11) When mounting multiple drivers on a single PC boardWhen mounting multiple drivers on a single PC board, the GND design should mount a VCC decoupling capacitor, C2 and C3, for each driver to stabilize the GND potential of the other drivers.

上面的设置中，L 代表拨码开关拨到ON 的位置，H 代表拨码开关拨到OFF 的位置.(备注：在1细分设置下，速度与力度是最高的，1/128设置是转速最低最平稳的)2. 最大输出电流为2.2A,可以适配2A 以内的各种2相小型步进电机，电流0.2-2A 无级可调，任意设置。

电位器是无级的，电流刻度标记是供参考用的。

如果你的电机是0.5A的调到0.4A与0.6A刻度的中间即可。

3.输入工作电压为DC9-32V.配有电源指示灯。

4.输入电路有防电源接反设计，更安全。

为靠近LED 指示灯位置的电位器设置。

匹配电机时，调该电位器，使电机的震动与噪声最小即可。

7.行业标准的输入输出接口，兼容性强，可以支持共阴或共阳接法。

8.配有大型散热器，与安装固定柱，螺丝，使用更方便。

注意事项：1.驱动器匹配的电源容量最少都要有2A以上。

否则工作不稳定。

2.电机线不得AB相线交叉接，否则烧驱动器。

3.配PLC使用时，要加串2K左右限流电阻，否则烧驱动器。

附录：步进电机驱动使用注意事项1.关于电机驱动器电源的选用：每个驱动器的工作电源必须大于驱动器的最大驱动电流安数以上的容量。

平时工作作电流一般不是很大。

但电机在换向与启动时，一般电流会提升3-4倍左右或以上，视电机负载而定。

在选用电源时，要选用大容量的，浪涌冲击能力好的电源。

尽量选用开关电源供电。

在要求稳定性高的场合，不建议使用没有稳压功能的工频变压器整流滤波后的电源供电，因为这样会给步进电机的正常工作带来很多不稳定因素。

Description of functions 9-1) Stand-by functionWhen ST/VCC pin is at low levels, the IC enters stand-by mode, all logic is reset and output is turned OFF. When ST/VCC pin is at high levels, the stand-by mode is released. 9-2) Step pin functionCLK pin step signal input allows advancing excitation step.9-3) Excitation setting methodSet the excitation setting as shown in the following table by setting M1 pin, M2 pin and M3 pin.Input Initial position M3 M2 M1 Mode(Excitation ) A phase current B phase current L L L 2 phase 100% -100% L L H 1-2 phase 100% 0% L H L W1-2 phase 100% 0% L H H 2W1-2 phase 100% 0% H L L 4W1-2 phase 100% 0% H L H 8W1-2 phase 100% 0% H H L 16W1-2 phase 100% 0% H H H 32W1-2 phase 100% 0%The initial position is also the default state at start-up and excitation position at counter-reset in each excitation mode.9-4) Output current settingOutput current is set as shown below by the VREF pin (applied voltage) and a resistance value between NFA (B) pin and GND. Iout = (VREF / 5)/ NFA (B) resistance* The setting value above is a 100% output current in each excitation mode.※(Example) When VREF=1.5V and NFA (B) resistance is 0.3 Ω, the setting current is shown below.Iout = (1.5 V / 5) / 0.3 Ω = 1.0 A9-5) Output enable functionWhen the ENABLE pin is set Low, the output is forced OFF and goes to high impedance. However, the internal logic circuits are operating, so the excitation position proceeds when the CLK is input. Therefore, when ENABLE pin is returned to High, the output level conforms to the excitation position proceeded by the CLK input.CLKB phMOHigh impeda nce outpu t9-6) Reset functionWhen the RESET pin is set Low, the output goes to initial mode and the excitation position is fixed in the initial position for CLK pin and CW/CCW pin input. MO pin outputs at low levels at the initial position. (Open drain connection)CLK RESET A phase out B phase ou MOInitial positionCW/CCW OperationL CWH CCWThe internal D/A converter proceeds by a bit on the rising edge of the step signal input to the CLK pin. In addition, CW and CCW mode are switched by CW and CCW pin setting.In CW mode, the B phase current is delayed by 90°relative to the A phase current. In CCW mode, the B phase current is advanced by 90°relative to the A phase current.9-8) DECAY mode settingCurrent DECAY method is selectable as shown below by applied voltage to the FDT pin.FDT voltage DECAY method3.5V to SLOW DECAY1.1V to 3.1Vor OPEN MIXED DECAYto 0.8V FAST DECAY9-9) DOWN, MO output pinOutput pin is an open drain connection. Each pin is turned ON at predetermined state and outputs at low levels.Pin state DOWN MOLowHoldingcurrent state Initial positionOFF Normalstate Non initial positionChopping frequency is set as shown below by a capacitor between OSC1 pin and GND.Fcp = 1 / (Cosc1 / 10×10-6) (Hz)(Example) When Cosc1=100pF, the chopping frequency is shown below.Fcp = 1 / (100×10-12 / 10×10-6) = 100 (kHz)9-11)Output current vector locus (1 step normalized 90°)Current setting ratio in each excitation mode9-12)Current wave example in each excitation mode (2 phase, 1-2 phase, W1-2 phase, 4W1-2 phase)2 phase excitation (CW mode)1-2 phase excitation (CW mode)CLKIA IB1000 －100 1000 －100 (%) (%)MOW1-2 phase excitation (CW mode) CLKIA IB1000 －1001000－100 (%) (%)MO4W1-2 phase excitation (CW mode)9-13) Output short-circuit protection circuitBuild-in output short-circuit protection circuit makes output to enter in stand-by mode. This function prevents the IC from damaging when the output shorts circuit by a voltage short or a ground short, etc. When output short state is detected, short-circuit detection circuit starts the operating and output is once turned OFF. After the timer latch time (typ: 256us), output is turned ON again. Still the output is at short state, the output is turned OFF and fixed in stand-by mode.When output is fixed in stand-by mode by output short protection circuit, output is released the latch by setting ST/VCC=”L”.9-14) Open-drain pin for switching holding currentThe output pin is an open drain connection.This pin is turned ON when no rising edge of CLK between the input signals while a period determined by a capacitor between OSC2 and GND, and outputs at low levels.The open-drain output in once turned ON, is turned OFF at the next rising edge of CLK.Holding current switching time (Tdown) is set as shown below by a capacitor between OSC2 pin and GND.Tdown = Cosc2 × 0.4×109 (s)(Example) When Cosc2=1500pF, the holding current switching time is shown below.Tdown = 1500 pF × 0.4×109 = 0.6 (s)10. Current control operation10-1) SLOW DECAY current control operationWhen FDT pin voltage is a voltage over 3.5 V , the constant-current control is operated in SLOW DECAY mode. (Sine-wave increasing direction)Coil cufch opC H AR G E CLKC u r r e n t m ode(Sine-wave decreasing direction)C oil c u rfch o pC L KS et t i n g C u r re n tEach of current modes operates with the follow sequence.● The IC enters CHARGE mode at a rising edge of the chopping oscillation.(A period of CHARGE mode (Blanking Time) is forcibly present in approximately 1 μs, regardless of the current value of the coil current(ICOIL)and set current (IREF)).● After the period of the blanking time, the IC operates in CHARGE mode until ICOIL ≥IREF. After that, the mode switchesto the SLOW DECAY mode and the coil current is attenuated until the end of a chopping period.At the constant-current control in SLOW DECAY mode, following to the setting current from the coil current may take time (or not follow) for the current delay attenuation.When FDT pin voltage is a voltage under 0.8V , the constant-current control is operated in FAST DECAY mode. (Sine-wave increasing direction)Coil cufch opCLKC ur r en t(Sine-wave decreasing direction)C oil c u rfch o pC L KS e t t i n g C u r r e n tEach of current modes operates with the follow sequence.● The IC enters CHARGE mode at a rising edge of the chopping oscillation.(A period of CHARGE mode (Blanking Time) is forcibly present in approximately 1 μs, regardless of the current value of the coil current (ICOIL) and set current (IREF)).● After the period of the blanking time, The IC operates in CHARGE mode until ICOIL ≥ IREF. After that, the modeswitches to the FAST DECAY mode and the coil current is attenuated until the end of a chopping period.At the constant-current control in FAST DECAY mode, following to the setting current from the coil current takes short-time for the current fast attenuation, but, the current ripple value may be higher.When FDT pin voltage is a voltage between 1.1 V to 3.1 V or OPEN, the constant-current control is operated in MIXED DECAY mode. (Sine-wave increasing direction)Coil cufch opC H AR G ES TPC u r r en t m ode(Sine-wave decreasing direction)C oi l c u rfc h opC L KS e t t i n g c C u r r e n t mEach of current modes operates with the follow sequence.●The IC enters CHARGE mode at a rising edge of the chopping oscillation.(A period of CHARGE mode (Blanking Time) is forcibly present in approximately 1 μs, regardless of the current value of the coil current (ICOIL) and set current (IREF)).●In a period of Blanking Time, the coil current (ICOIL) and the setting current (IREF) are compared.If an ICOIL < IREF state exists during the charge period:The IC operates in CHAGE mode until ICOIL ≥ IREF. After that, it switches to SLOW DECAY mode and then switches to FAST DECAY mode in the last approximately 1 μs of the period.If no ICOIL < IREF state exists during the charge period:The IC switches to FAST DECAY mode and the coil current is attenuated with the FAST DECAY operation until the end of a chopping period.The above operation is repeated.Normally, in the sine wave increasing direction the IC operates in SLOW (+FAST) DECAY mode, and in the sine wave decreasing direction the IC operates in FAST DECAY mode until the current is attenuated and reaches the set value and the IC operates in SLOW (+FAST) DECAY mode.11.
