Operation during compensation mode
Program paths commanded by movement commands (G00, G01, G02, G03) are compensated to get the tool center path
from a line/arc.
• If the same compensation command (G41/G42) is commanded during compensation mode it is ignored.
• If four blocks or more that do not command movement are consecutively commanded during compensation
mode, overcutting or undercutting occurs.
• During compensation mode, if M00 or M01 are commanded, pre-read becomes prohibited.
