Using Intelligent Input Terminals
The figure below shows the operation during an overload restriction event. The overload restriction level is set by B022 and B025. The overload restriction constant is the time to decelerate to 0Hz from maximum frequency. When this function operates, the acceleration time will be longer than the normal acceleration time.
