I have ATV71 with Error SCF1 , what is that error and how to solve it ?

SCF1 to SCF5 is a  Motor short-circuit fault

The causes could be :
• Short-circuit or earthing at the drive output
• Significant earth leakage current at the drive output if several motors are connected in parallel

To Solve it
• Check the cables connecting the drive to the motor, and the insulation of the motor.
• Reduce the switching frequency.
• Connect chokes in series with the motor.
