The bit [Axis Not Used/Used] indicates the status of whether the concerned
axis can be used or not. The bit [Axis Not Used/Used] reflects the execution
status as compared to the bit [Busy] will not be turned OFF until the command
output is turned OFF. The bit [Busy] does not reflect status in Automatic Mode
while the bit [Axis Not Used/Used] reflects status in Automatic Mode.
Name
Axis Not Used/Used 0: Axis is not being used.
1: Axis is being used.
(In Manual Mode: Axis is used for JOG etc., In Automatic
Mode: Axis is declared in the operating program)
• In Manual Mode, the bit [Axis Not Used/Used] is turned ON during execu-
tion of the following functions to indicate that the axis is being used in
Manual Mode.
Function
Axis Control Bit: JOG
Axis Control Bit: STEP
Axis Control Bit: Origin Search
Axis Control Bit: Machine Origin Return
• In Automatic Mode, the bit [Axis Not Used/Used] for the axis declared in
PROG command will be turned ON when the program is started to indi-
cate that the axis is being used.
• 1-shot output may occur. In that case, depending on the Scan Time of the
ladder program and the Unit Scan Time of the MC Unit, the output may
not be reflected in the ladder program.
• In Manual Mode
No effect. (The bit [Busy] also has effect on the functions affected by this
bit. Duration of the bit [Busy] staying ON is longer than that of the bit [Axis
Not Used/Used], which means that the bit [Busy] includes the bit [Axis Not
Used/Used] consequentially.
• In Automatic Mode
The axis for which the bit [Axis Not Used/Used] is ON cannot be used in
other motion programs. When starting a program that declared an axis
already in use, the bit [Start Warning] will be turned ON. Therefore, the
motion program cannot be executed.
