[St.2124] Base/tool translation change complete (M43908+32m)
This signal turns ON with the completion of base/tool transformation change. The signal turns OFF at the trailing edge
(ONOFF) of "[Rq.2244] Base/tool translation change command (M43620+32m)".
Refer to base/tool transformation change function for details on base/tool transformation change. (Page 101 Base/Tool
Transformation Change Function)
[St.2127] Machine start accept flag (M43911+32m)
• This flag turns ON when the machine is started. The machine start accept flag, and "[St.1040] Start accept flag (R:
M30080+n/Q: M2001+n)" of the machine configuration axes turns ON. "[St.2127] Machine start accept flag (M43911+32m)"
also turns ON when any of the machine configuration axes is started.
• The machine start accept flag turns ON when the following controls are being executed.
Machine operation
Other than machine operation
(Machine configuration axis)
• A current value change by servo program CHGA instruction to the machine configuration axes, or by the Motion dedicated
PLC instruction (M(P).CHGA/D(P).CHGA), turns ON "[St.1040] Start accept flag (R: M30080+n/Q: M2001+n)", and
"[St.2127] Machine start accept flag (M43911+32m)" of the axes that execute the current value change.
• A base/tool transformation change by "[Rq.2244] Base/tool translation change command (M43620+32m)" does not turn ON
"[St.1040] Start accept flag (R: M30080+n/Q: M2001+n)" of the machine configuration axes, and "[St.2127] Machine start
accept flag (M43911+32m)".
CAUTION
Do not turn the machine start accept flags ON/OFF in the user side.
• If the machine start accept flag is turned OFF using the program or user operation while this flag is ON, no error will occur but the positioning operation will
not be reliable. Depending on the type of machine, unpredictable operations can occur.
• If the machine start accept flag is turned ON using the program or user operation while this flag is OFF, no error will occur but the "start accept on error" will
occur at the next starting and cannot be started.
[St.2128] Machine servo ready (M43912+32m)
• When "[St.1075] Servo ready (R: M32415+32n/Q: M2415+20n)" of all axes that make up the machine are turned ON,
"[St.2128] Machine servo ready (M43912+32m)" turns ON.
• When "[St.1075] Servo ready (R: M32415+32n/Q: M2415+20n)" of one of the configuration axes turns OFF, "[St.2128]
Machine servo ready (M43912+32m)" turns OFF.
