• The following can be monitored with the PLC function special register.
NOTE
• For the details of the monitor selection, refer to page 359 of the Instruction Manual (Detailed).
• For the details of the PLC function special register, refer to page 22 of the PLC Function Programming Manual.
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  (Cumulative pulse carrying-over times 
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 carrying-over 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 clearance method for the cumulative pulse
monitor and the cumulative pulse carrying-over times.
Cumulative pulse storage
• The cumulative pulse monitor value can be retained when the power is turned OFF or the inverter is reset.
NOTE
• When the power is turned OFF during the reset process, the cumulative pulse monitor value and the cumulative
pulse carrying-over times are not stored in the EEPROM.
