Processing details
• The G00 command is modal. It remains in effect until another G-code from the same group is used. When G00 is
continuous, from the next block and after, it can only be commanded by coordinate language.
• ",F" command is only valid in the block specified. When an ",F" command is in the same block as G00 command,
positioning is performed at the ",F" command speed. When there is no ",F" command, positioning is performed at the speed
set in [Motion Control Parameter][G-code Control Parameter][G-code Control Axis Parameter]"Speed/Time
Constant""Fast Forward Speed".
• When there is no ",F" command during high-accuracy control mode, positioning is performed at the speed set in [Motion
Control Parameter][G-code Control Parameter][G-code Control Axis Parameter]"High-accuracy control""Rapid
traverse rate during high-accuracy control mode". However, when the setting value of rapid traverse rate during high-
accuracy control mode is "0", positioning is performed at the speed set in [Motion Control Parameter][G-code Control
Parameter][G-code Control Axis Parameter]"Speed/Time Constant""Fast Forward Speed".
• The setting of the movement path (linear, or non-linear) to the specified coordinate axis position is made in [Motion Control
Parameter][G-code Control Parameter][G-code Control System Parameter]"Control Setting""G00 Non-
Interpolation". The positioning time of linear path and non-linear path are the same.
• In a G00 command, acceleration and deceleration are always performed at the start point and end point. A deceleration
check is performed at the end point, and all moving axes in each line are checked for completion before moving to the next
block.
• There are three methods for deceleration check. They are command deceleration check method, smoothing check method,
and in-position check method. Set the deceleration check method to be used in fast forward/cutting in [Motion Control
Parameter][G-code Control Parameter][G-code Control System Parameter]"Control Setting""Deceleration Check".
Refer to deceleration check for deceleration check. (Page 178 Deceleration check)
