■ D8192 to D8203, D8210 to D8213, D8216 to D8229, D8232 to D8237: High-speed Counter
These special data registers are used with the high-speed counter function and the frequency measurement function.
For details on high-speed counters, see Chapter 5 "High-Speed Counter" in the "FC6A Series MICROSmart User's Manual".
D8210 to D8213, D8216, D8217 = High-speed counter (group 1/I0)
D8218 to D8221, D8234, D8235 = High-speed counter (group 3/I3)
D8222 to D8225, D8236, D8237 = High-speed counter (group 4/I4)
D8226 to D8229, D8232, D8233 = High-speed counter (group 5/I6)
D8192 to D8197 = High-speed counter (group 2/I1)
D8198 to D8203 = High-speed counter (group 6/I7)
■ D8239: Absolute Position Control Status
This register indicates the status of absolute position control.
The allocation of the absolute position counter initialized flags in the device (bit assignment) is as follows. For details on the
absolute position control status, see "ABS (Set Absolute Position)" on page 18-68.

0: Not initialized
1: Initialized
■ D8240 to D8247: Absolute Position Counter 1 to 4
The absolute position is written to these registers according to pulse output. The absolute position can be initialized with the
ABS instruction.
When reversible control is set in the pulse output instructions (RAMP/ARAMP/ZRN/JOG), the absolute position is incremented or
decremented according to the output result. For details on absolute position counters, see "ABS (Set Absolute Position)" on page
18-68.
D8240, D8241 = Absolute position counter 1
D8242, D8243 = Absolute position counter 2
D8244, D8245 = Absolute position counter 3
