Hiding the decimal places for the monitors (Pr. 268)
The numerical figures after a decimal point displayed on the operation panel may fluctuate during
analog input, etc. The decimal places can be hidden by selecting the decimal digits with Pr. 268.
Minus sign display for the monitors (Pr. 290)
Values with minus signs can be output from the terminal AM (analog voltage output) and can be dis-
played on the operation panel. For a list of the monitors that can output values with minus signs, refer
to the monitor description list (on page 5-328).
Pr. 268 setting Description
9999 (initial value) No function
0
For the first or second decimal places (0.1 increments or 0.01 increments) of the monitor, numbers in
the first decimal place and smaller are rounded to display an integral value (1 increments). The
monitor value equal to or smaller than 0.99 is displayed as 0.
1
When monitoring with the second decimal place (0.01 increments), the 0.01 decimal place is
dropped and the monitor displays the first decimal place (0.1 increments). When monitoring with
the first decimal place, the display will not change.

NOTE The number of display digits on the cumulative energization time (Pr. 52 = "20"), actual operation
time (Pr. 52 = "23"), cumulative power (Pr. 52 = "25") and cumulative energy saving (Pr. 52 = "51")
does not change.
