Note When the constant cycle time function is enabled for the Motion Control Mod- ule in ASync Mode, the Motion Control Module's cycle time will be constant.

5-6-2 Watch Cycle Time Function

If the real cycle time is longer than the set watch cycle time, operation will stop for all Modules and the Cycle Time Too Long Flag (A401.08) in the Auxiliary Area will turn ON.

System Setup

Tab page	Name	Details	Default
Timer/Peripheral Servic-	Cycle Time	0.1 to 100.0 ms	Variable
ing or Cycle Time		(unit: 0.1 ms)
	Watch Cycle Time	1 to 100 ms	50 ms
		(unit: 1 ms)

!Caution If the Cycle Time Too Long Flag turns ON for one Module in Sync Mode, the Cycle Time Too Long Flag will turn ON for all Modules.

Note The settings are made using CX-Programmer Ver. 5.0@ menus.

Cycle Time Too Long Flag

Cycle Time Too Long	A401.08	Turns ON if the cycle time PV exceeds the
Flag		Watch Cycle Time in the System Setup.

5-6-3 Cycle Time Monitoring Function

Every cycle, the maximum cycle time is stored in A206 and A207 and the PV is stored in A208 and A209 in the Auxiliary Area.

Auxiliary Area Words

Name	Addresses	Meaning
Maximum Cycle	A206 to A207	The maximum cycle time value is stored in
Time		binary each cycle. The time is measured in
		0.01-ms units.
Cycle Time PV	A208 to A209	The cycle time PV is stored in binary each
		cycle. The time is measured in 0.01-ms
		units.

The average cycle time for the last 8 scans can also be read from the CX-Pro- grammer.

Note The FQM1 can skip program areas that do not need to be executed by using the JMP-JME instructions to shorten cycle times.
