FR-A800 5 - 175
Cumulative pulse division scaling factor (Pr. 636, Pr. 637)
●
Set the division scaling factor on the cumulative pulse in Pr. 636 or Pr. 637.
●
Cumulative pulse count value calculation method
(Cumulative pulse count value) = (Cumulative pulse division scaling factor) x ((Cumulative pulse
overflow times) x 32768 + (Cumulative pulse monitor value))
Cumulative pulse count value: Number of pulses multiplied by 4
Cumulative pulse division scaling factor: Pr. 636 or Pr. 637
Cumulative pulse monitor value clear (Pr. 635)
●
The cumulative pulse monitor and the cumulative pulse overflow times can be cleared by X52
signal or X53 signal.
●
To input the X52 or X53 signal, set "52 (X52)" or "53 (X53)" in any of Pr. 178 to Pr. 184 (input terminal
function selection) to assign the function to a terminal.
●
Use Pr. 635 "Cumulative pulse clear signal selection" to select the clearing method for the
cumulative pulse monitor and the cumulative pulse overflow times.

0 Cleared at the edge when the signal is switched to ON. Cleared at the edge when the signal is switched to ON.
1 Cleared while the signal is ON. Cleared at the edge when the signal is switched to ON.
2 Cleared at the edge when the signal is switched to ON. Cleared while the signal is ON.
3 Cleared while the signal is ON. Cleared while the signal is ON.
