Post a copy of the segment of your CNC program where the issue is occurring.

the error alarm happen at N382

The error is being cause by block N384. It may appear as though N382 is the cause, but due to "look ahead buffering" the cause is in N384

Have you been able to use Helical Milling with this machine before, that is X,Y, and Z with G02/G03? This alarm normally occurs when an invalid plane is specified for G02/G03. If you haven't already, make sure G17 is programmed prior to block N384 being executed. If that doesn't fix the problem with the existing program, for the purpose of testing, remove the Z addresses in all the circular interpolation blocks to see if the program runs without error. If it does, then your control does not have the Helical Interpolation option.
