What to do if YASKAWA Control Unit shows A.02 Parameter Breakdown error?
If the YASKAWA Control Unit displays the A.02 Parameter Breakdown error, it could be due to several reasons. It might be that the power was turned off while writing parameters. In this case, initialize parameters using Fn005 and re-input your settings. Alternatively, the SERVOPACK or NS115 might be defective, requiring replacement.
