02-19
Terminal Counting Value Reached (returns to 0)

Settings
 The counting function is enabled when Pr.02-19 ≠ 0.
 You can set the input point for the counter using the multi-function terminal MI6 as a trigger
terminal (set Pr.02-06 to 23). When counting is completed, the specified multi-function output
terminal is activated (Pr.02-13, Pr.02-16, or Pr.02-17 is set to 18). Pr.02-19 cannot be set to 0 at
this time.
For example, if the keypad displays c5555, it means that the counting value is 5,555. If the
keypad displays c5555●, then the actual counting value is 55,550–55,559.

Preliminary Counting Value Reached (does not return to 0)

Settings
 Use this parameter with Pr.02-19.
 When the count value counts from 1 to reach this value, the corresponding multi-function output
terminal is activated (Pr.02-13, Pr.02-16, or Pr.02-17 is set to 17) and keeps counting to the last
count value. You can use this parameter as the end of counting to make the drive run from the
low speed to stop.
 The timing diagram is RY1 activates when the count value is three, and the display returns to
zero when counts to five:
