High-speed counter function of ELC-PC/PA series is the same as that of ELC-PH series with
the addition of 1-phase 1 input and 2-phase 2 inputs. For 1-phase 1 input, the highest
frequency of X10 (C243) and X11 (C245) can each be up to 100kHz with total bandwidth
130kHz. For 1-phase 2 inputs (X10, X11) C250, the highest frequency is 100kHz. For
2-phase 2 inputs (X10, X11) C255, the highest frequency is 50kHz.
d) C243 can be set for rising-edge counting, falling-edge counting or rising and falling edge
counting. C245 and C250 can only be set as rising-edge counting or falling-edge counting.
C255 can only be used in 4 times frequency counting and cannot be set as rising-edge or
falling-edge counting.
e) When C243 or C245 is used, C250 or C255 cannot be used. Also, when C250 or C255 is in
use, C243 or C245 cannot be used.
Input X5 has two functions:
1.
When M1260=OFF, C240 is a general U/D high-speed counter.
2.
When M1260=ON, X5 is the global reset for C235~C239.

a) When DHSCS and DHSCR use an additional high-speed counter, the maximum high-speed
the instruction can use are the settings of two sets of high-speed comparison instructions.
b) When additional high-speed counter is used with DHSZ, only a set of comparison
instructions can be used.
