您好,我在PIC16F1937的设计中使用NEMA 23步进电机来驱动电动拖曳电机。我使用的是ON半导体STK68电机驱动器,它将12V方波发送到步进电机。我的问题是当我有4针电缆连接电路板到步进电机时,即使STK68电机驱动器被禁用,它也会对它供电。我也不能通过连接到步进器的ICD3在调试模式下运行代码。当我尝试进入调试器时,它会在编程PIC时敲出ICD3。我如何发布示意图?谢谢

I'm using the On Semiconductor STK682 motor driver that sends the 12V square waves to the stepper motor. My problem is when I have the 4-pin cable connecting the circuit board to the stepper motor it has I high pitch whine on powering it even though the STK682 motor driver is disabled. I also cannot run the code in debug mode via the ICD3 with the stepper connected. When I try to enter the debugger it knocks out the ICD3 when programming the pic. How can I post the schematic? Thanks |

这里是STK62数据表中的一张图片:你可以将你的示意图作为屏幕截图(如我上面所说的那样)。如果运行步进电机敲除调试器,则很可能是电源或EMI的尖峰在CLK和数据线上被拾取。您可能希望使用光电耦合器或数字隔离器来驱动信号,并使用单独的隔离电源来驱动电机和驱动器。适当的电容旁路,良好的接地技术,铁氧体磁珠,和屏蔽可能是必要的。
以上来自于百度翻译 以下为原文 Here is an image from the STK682 data sheet: You can post your schematic as an image from a screen shot (as I did above). If running the stepper motor knocks out the debugger, it is most likely spikes in the power supply or EMI being picked up on the CLK and DATA lines. You might want to use opto-couplers or digital isolators for the drive signals, and use a separate isolated supply for the motor and driver. Proper capacitive bypassing, good grounding techniques, ferrite beads, and shielding may be necessary. |

步进电机驱动器通常通过线圈限制电流。这可能引起抱怨。如果是这样,减少VM应该降低啸叫的频率。或在开发过程中增加引脚8, 12的感测电阻器的值。这将减少抱怨-不幸的是扭矩。但在开发过程中,减少的扭矩是可以接受的。我所缺少的是VCC和GND之间的某种限制。
以上来自于百度翻译 以下为原文 Stepper drivers usually limit the current through the coils. This might cause the whine. If so, reducing VM should lower the whine's frequency. Or increasing the value of the sense resistors at pins 8, 12 during development. This would reduce the whine - unfortunately the torque as well. But during development a reduced torque may be acceptable. What I'm missing is some cap between VCC and GND. |

电池电压是多少?你使用的是真正的电池还是一些电源(额定值?)在开发过程中?
以上来自于百度翻译 以下为原文 What is the battery voltage? And do you use a real battery or some power supply (ratings?) during development? |
