- Programmable mirror image
The mode switching between hypothetical axis command mode and real axis
command mode must be commanded after canceling programmable mirror image
mode.
If the mode switching is commanded during programmable mirror image mode, the
alarm (P/S5359) is generated.
- Coordinate system rotation
The mode switching between hypothetical axis command mode and real axis
command mode must be commanded after canceling coordinate system rotation
mode.
If the mode switching is commanded during coordinate system rotation, the alarm
(P/S5359) is generated.
- Canned cycle
The mode switching between hypothetical axis command mode and real axis
command mode must be commanded after canceling canned cycle mode.
If the mode switching is commanded during canned cycle, the alarm (P/S5359) is
generated.

- Rapid traverse (G00)
Rapid traverse command (G00) is allowed in case the parameter LRP (No.1401#1) is
set to “1”.
In case parameter LRP (No.1401#1) is set to “0”, the alarm (P/S5359) is generated at
mode change between the hypothetical axis command mode and the real axis
command mode.

And in order to keep linear motion during G00 command, the parameter
RTC(No.1603#4) has to be set to “1”.
- Simple synchronous control
Simple synchronous control can be applied to the real axis out of the hypothetical
plane. The hypothetical axes and the real axes in the hypothetical axes cannot be
applied the simple synchronous control.

allowed on the hypothetical axes in the hypothetical axis command mode or on the
real axes in the real axis command mode.

- Page 31 General By this function, the machine having two linear axes and one rotary axis, not having 3 linear axes, can be controlled as a normal X-Y-Z axes machine. The linear axis not having a real axis becomes a hypothetical axis and it is necessary that hypothetical axis is set as one of CNC controlle
