For RS-485 communication, the display increments are 1. For example, 10.00kWh indicates that communication data is 10.
When using the parameter unit (FR-PU04/FR-PU07), "kW" is displayed.
REMARKS
Since four digits are displayed on the operation panel, the value is displayed in 0.1 increments when a monitor value in 0.01
increments exceeds 99.99, then rounded up to 100.0. The maximum display is "9999".
As the operation panel (FR-PU04/FR-PU07) is 5-digit display, it displays in 0.1 increments since a carry occurs, e.g. "1000.0",
when a monitor value in 0.01 increments exceeds "999.99". The maximum display is "99999".
The upper limit of RS-485 communication is "65535" when Pr. 898 Power saving cumulative monitor clear = "9999". The upper
limit of 0.01 increments monitor is "655.35" and that of 0.1 increments monitor is "6553.5"
