7.14.3 Operation timing 

(1) Operation cycle alarm, operation cycle warning occurrence timing 

A timing chart for when the operation cycle exceeds the warning level (95% of the control cycle) and alarm 
level (100% of the control cycle) is shown below.

(2) Operation cycle monitor clear timing 

When the operation cycle monitor clear signal (OCMC) is turned on, the during operation cycle monitor 
clear (OCMCO) is turned on. Then, the operation cycle alarm signal (OCME) and operation cycle warning 
signal (OCMW) are turned off, and each data item in the operation cycle monitor data is cleared to 0.

POINT 

 

• When the operation cycle alarm signal (OCME) and operation cycle warning 

(OCMW) are turned on, the load of the motion operation is high. Review the 
following contents. 

• Extend the control cycle in the setting. 

(Example. When the control cycle is 0.44 ms, change it to 0.88 ms.) 

• Set less control axes. 

• Reexamine the operation pattern so that each axis does not start operation 

simultaneously. 

• For software version A4 or later, when operation cycle alarm (OCME) turns 

ON operation cycle alarm (system alarm 35, detail No.01) occurs. Operation 
continues even when operation cycle alarm (system alarm 35, detail No.01) 
has occurred. When clearing operation cycle alarm (system alarm 35, detail 
No.01) turn ON system alarm reset signal (CRST).
