6-426.4.9 Action of the Flag concerning Linear Interpolation and CircularInterpolationKey Point:Can be used with C32T2, C28P2, C32T2H and C28P2H only.Table of flag AllocationAddress Flag conditions The uses of the flag in the programR903AControl flag(CH0)Turns on during execution of pulse outputinstructions that include a circularinterpolation instruction and then maintainsthat state during pulse output from CH0.This flag is the same for instructions F166 toF176.Use this to prohibit the simultaneousexecution of other high-speed counterinstructions and pulse outputinstructions, and to verify completionof an action.R903CControl flag(CH2)Turns on during execution of pulse outputinstructions that include a circularinterpolation instruction and then maintainsthat state during pulse output from CH2.This flag is the same for instructions F166 toF176.Use this to prohibit the simultaneousexecution of other high-speed counterinstructions and pulse outputinstructions, and to verify completionof an action.R904EControl flagfor circularinterpolationTurns on hen circular interpolationinstruction F176 starts up and maintainsthat state until the target value is reached.When the target value has not beenreached even if the circular interpolationinstruction execution condition is off, thatstate is maintained.Use this to prohibit the simultaneousexecution of other high-speed counterinstructions and to verify completion ofa circular interpolation action. Whenthis flag is on, other positioninginstructions F171 to F176 cannot bestarted.R904FConfirmationflag foroverwritingcircularinterpolationTurns on for one scan when the circularinterpolation instruction F176 starts up.(The set time is ON time when theperiodical interrupt program is executed.)When conducting control with thecontinuous mode for performingcontinuous circular interpolationactions, use this after circularinterpolation instruction startup whenoverwriting the next target value.Note:• When the target value has not been reached and the execution condition is off, circular interpolationcontrol flag R904E turns on and other positioning instructions F171 to F176 cannot be start up.• The above flags vary during scanning.Example: If the above flags are used for more than one time as input conditions, there may be thedifferent states in the same scan. Replace with internal relays at the beginning of the program as ameasure.
