Why does my YAKO Servo Drives show a resettable NO.1 fault?
- JjwebsterAug 6, 2025
A resettable NO.1 fault in YAKO Servo Drives can be triggered by several factors, including a main circuit DC voltage that is abnormally high or low. It can also be caused by the speed command exceeding the maximum speed value, a UVW phase sequence error, a speed response that's too high and severely exceeds the adjustment range, or a drive failure. Another cause is assigning different Digital Inputs (DI) with the same function repeatedly, assigning different Digital Outputs (DO) with the same output, or a reference position failure.
