MAX22216

Thread Summary

The user is experiencing a HHF fault when using the Max22216 to control an electromagnetic valve in CDR mode with VM at 24V and a 240Ω resistor. The final answer suggests checking if the current ever reaches 90mA and adjusting both Kp and Ki parameters, as the issue may be due to inappropriate PI settings.

我在使用Max22216控制电磁阀时,VM为24V,电磁阀电阻为240欧,我使用CDR模式进行闭环控制,我设置DC_L2H为90mA,DC_H为60mA,最终电流稳定在60mA,但会产生一个故障告警HHF,调大L2H_TIME或者改大kp,仍然报这个错误,调小DC_L2H的值,问题依旧存在。
