I am working with a Siemens 6SE7016-1TA51 Simovrt MC drive, and I am encountering fault code F026. I have already checked the motor, fiber optic cable, and everything seems to be in good condition. Additionally, the current transformer (CT) on the power card was replaced, but the same fault persists.

Could you please suggest a solution to resolve this issue?
