你好， 使用L6472时，我听到电机在听到时会发出声音（高音）噪音。 噪声量随着保持电流的增加而增加。电机是否装载无关紧要。当我查看带有示波器的绕组时，典型的pwm信号锁定和占空比适合保持设定值另一对绕组看起来“解锁”，频率比其他绕组高得多。 EVAL Bd硬件 24v电源，电流设定点.35amp Nema17,18mh / 8.9ohms，0.9度步进角有一个我忽略的环境L6470不会发生这种情况。 感谢您的支持 ！以上来自于谷歌翻译以下为原文 Hello, With L6472 I hear audible (high pitch) noise from motor when holding. volume of noise increase with increase hold current. It does not matter if the motor is loaded or not.When I look at winding with scope one pair is the typical pwm signal locked and duty cycle appropriate for the hold setpoint The other pair of windings appear ‘unlocked’ and much higher in frequency than the other winding. EVAL Bd hardware 24v supply, current set point .35amp Nema17, 18mh / 8.9ohms, 0.9degree step angleIs there a setting I am overlooking This does not occur with L6470. thanks for your support !
