(M) Monitor display and monitor output signal
Energy saving monitor list
• The items that can be monitored on the power saving monitor (Pr.52, Pr.54, Pr.158, Pr.774 to Pr.776 = "50") are indicated
below. (Only [1 Power saving] and [3 Average power saving] can be set to Pr.54 (terminal FM) and Pr.158 (terminal AM).)

• The items that can be monitored on the cumulative energy saving monitor (Pr.52, Pr.774 to Pr.776 = "51") are indicated
below.
(The monitor value of the cumulative monitor can be shifted to the right with Pr.891 Cumulative power monitor digit
shifted times.)


For communication, (RS-485 communication, communication option), the display increments are 1. For example, "10.00 kWh" is displayed as
"10" for communication data.

When using the LCD operation panel or the parameter unit, "kW" is displayed

The increment differs according to capacities. (FR-A860-01080 or lower / FR-A860-01440 or higher.)
NOTE
• The operation panel and the parameter unit have a 5-digit display. This means, for example, that when a monitor value in
0.01 units exceeds "999.99", the decimal place is moved up as in "1000.0" and the display changes to 0.1 units. The
maximum display number is "99999".
• The maximum value for communication (RS-485 communication, communication option) when Pr.898 Power saving
cumulative monitor clear = "9999" is "65535". The maximum value for the 0.01-unit monitor is "655.35", and the maximum
value for the 0.1-unit monitor is "6553.5".
