WARNING
1. Items related to operation
If the operation start position is set in a block which is in the middle of the program and
the program is started, the program before the set block is not executed. Please confirm
that G and F modal and coordinate values are appropriate. If there are coordinate system
shift commands or M, S, T and B commands before the block set as the start position,
carry out the required commands using the MDI, etc. If the program is run from the set
block without carrying out these operations, there is a danger of interference with the
machine or of machine operation at an unexpected speed, which may result in breakage
of tools or machine tool or may cause damage to the operators.

Under the constant surface speed control (during G96 modal), if the axis targeted for the
constant surface speed control moves toward the spindle center, the spindle rotation
speed will increase and may exceed the allowable speed of the workpiece or chuck, etc.
In this case, the workpiece, etc. may jump out during machining, which may result in
breakage of tools or machine tool or may cause damage to the operators.
