Measures to Take
Correct the program so that G141 is not selected before W-axis movement by side A command, or that G141 is not selected on side A when W-axis movement is executed by side B command.
1)Specify the W-axis movement command while the second workhead is unclamped.
Move the W-axis using G154(W-axis positioning command).
