*3 About the minimum revolution speed (minimum ow)
*4 About the frequency of the moving average
*5 About the pre-arithmetic function
When you set a value larger than 1 in the function item “F7 Minimum revolution speed (minimum ow)”,
the following functions can be used.
● In mode 1 and mode 2, the display value is “0” when the measurement revolution speed becomes less than
the minimum revolution speed(In mode 2, the display shows “-.-.-.-.-.-.”).●●
● In mode 4, the display value is “0” when the measurement display value becomes less than the minimum ow.
Mode
1: Judgment condition: (Input frequency/P1 setting value)
*
60 ● Minimum revolution speed ● Display value = “0”
Mode
2: Judgment condition: (Input frequency/P1 setting value)
*
60 ● Minimum revolution speed ● Display value = “-.-.-.-.-.-.”
Mode 3: No judgment
Mode 4: Judgment condition: Display value < Minimum ow ● Display value = “0”
When you select values other than “0” in the function item “F8 Frequency of moving average”, the frequency of the
moving average function can be used.
Displays the measurement value per display cycle averaged by the frequency of the moving average.
When you select “1” in the function item “F9 Pre-arithmetic function”, the pre-arithmetic function can be used.
Promptly performs the deceleration display when the input signal is lost.
● When the moving average function is not set (F8 setting value “0”)
When the auto zero function is activated, the display becomes “0” (“-.-.-.-.-.-.” in mode 2 and mode 3).
Displays the measurement value per display cycle averaged by the frequency of the moving average.
The gure below shows the relationship between the display update in the F8 setting “0” (moving average: 3 times) and
averaging.
● When the moving average function is set (F8 setting value “1”, “2”)
