The settings of related function parameters in the preceding gure are as follows:
Function Code Parameter Name Setting Description
Any of F4-00 to F4-09 DIx function selection 25 Counter input
Any of F4-00 to F4-09 DIx function selection 26 Counting reset
Any of F5-00 to F5-05 DOx function selection 8 Set counting value reached
Any of F5-00 to F5-05 DOx function selection 9 Designated counting value reached
● For high pulse frequency, use terminal DI5.
● You cannot allocate "Set counting value reached" function and "Designated
counting value reached" function to the same DO terminal.
● The counter keeps counting in the drive running/stop status. It stops counting
until the set counting value is reached.
● The counting value is retentive at power down.
● An automatic stop system can be implementing by connecting the output
counting value reached signal of DO to the stop input terminal.
