Hello everyone, I have a problem that Our acs550 don't triggers a fault when overload but the frequency reduce to 3Hz. The driver use for xxxx to transport cement. I don't find anything related to this problem in 3AFE64804588 document. Anyone can help me to understand this mode and change the mode to triggers overload fault when overload. Thank you so much.
I would suspect, Current limiter or torque limiter function is getting enabled and reducing the motor speed. Please check your limit settings and increase the maximum current and torque with respect to the application requirement.
