我购买了L6229Q评估板并连接到三相BLDC电机(H1,H2,H3,OUT1,OUT2,OUT3)。我将VDD和EN连接到5V电源,SGND和VS连接到带PGND的12V电源。当我将0-5V信号施加到Vref(SGND参考)时,我没有响应,当我手动旋转电机时,TACHO上没有输出(但我可以看到PIN 25-27获得正确的5V输入。)
这是一个糟糕的设备还是我误解了连接? #l6229-l6229q 以上来自于谷歌翻译 以下为原文 I purchased the L6229Q eval board and have connected to a 3-phase BLDC motor (H1, H2, H3, OUT1, OUT2, OUT3). I have VDD and EN connected to a 5V supply with SGND and VS connected to a sceond 12V supply with PGND. I am getting no response when I apply 0-5V signal to Vref (SGND reference) and there is no output on TACHO when I rotate the motor by hand (but I can see PIN 25-27 getting correct 5V inputs.) Is it a bad device or have I misunderstood connections? #l6229-l6229q |

更多信息:我现在还将F / R和BRAKE连接到+ 5V,电路板吸收大电流~0.2A,电机在停止前瞬间旋转。董事会在这个时候变得非常热。断开F / R并允许其浮动和循环供电将导致反向旋转的短暂操作(如手册中所建议的那样将F / R连接到GROUND甚至没有任何操作。)
即使电机相断开,电路板也会消耗大电流 - 设备内的输出电路似乎很短。 以上来自于谷歌翻译 以下为原文 Further info: I have also connected F/R and BRAKE to +5V now, the board draws high current ~0.2A and motor spins momentarily before stopping. The board gets very hot in this time. Disconnecting F/R and allowing this to float and cycling power will cause brief operation in reverse rotation (connecting F/R to GROUND as suggested in manual does not have any operation even briefly.) Board also draws high current even with motor phases disconnected - seems like short in output circuit inside device. |

嗨,谢谢你的帖子。
是的,我已经确认手动旋转时大厅状态发生变化(引脚8-10上出现+ 5V)。根据我的电机数据表,OUT1似乎与H1正确同步,所以我已经订购了额外的评估板,以防这个损坏。 以上来自于谷歌翻译 以下为原文 Hi, thanks for your post. Yes, I have confirmed when rotating by hand the hall states change (+5V appearing on pin 8-10). OUT1 appears to be correctly synchnozied with H1 according to the motor datasheet I have, so I have ordered additional eval boards in the case this one is damaged. |
