Details
The commanded G code cannot be performed during 3-dimensional coordinate conversion
modal.
Remedy
- Refer to "MITSUBISHI CNC 700/70 Series Programming Manual (Machining Center Sys-
tem)" for usable G commands.
- When the parameter "#8158 Init const sur spd" is enabled, disable the parameter or issue
the constant surface speed control cancel (G97) command.
