[St.1046] Operation cycle over flag (R: M30054/Q: M2054)
This flag turns on when the time concerning motion operation exceeds the "Motion setting operation cycle (SD523)". Refer to
the following for details.
MELSEC iQ-R Motion controller Programming Manual (Common)
Perform the following operation, in making it turn off.
• Turn the Multiple CPU system power supply ONOFF
• Reset the Multiple CPU system
• Reset using the user program
■Countermeasures for operation cycle over
• Change the operation cycle to a larger value in the [Motion CPU Common Parameter]  [Basic Setting]  "Operation
Cycle".
• Reduce the number of executions of event task and NMI task instructions in the Motion SFC program.
[St.1040] Start accept flag (R: M30080+n/Q: M2001+n)
• This flag turns on when axis control is started by the servo program or the command signals. The start accept flag of the
controlled axis turns ON.
• The start accept flag turns ON when the following control is being executed.
• Servo program
• Direct positioning control by the Motion dedicated PLC instruction (M(P).SVSTD/D(P).SVSTD)
• JOG operation
• Manual pulse generator operation
• Speed-torque control
• Synchronous control operation (output axis)
• Current value change
• Pressure control
• Machine program operation
• Machine JOG operation
• G-code control
• The state of the start accept flag during positioning control by servo program is shown below.
