 Actual operation time monitoring (Pr.171, Pr.564)
• On the actual operation time monitoring (Pr.52 = "23"), the inverter running time is added up every hour. (Time is not added
up during a stop.)
• The time is displayed in 1-hour increments.
• The values are stored in EEPROM every 10 minutes. The EEPROM is also updated at power OFF.
• When the cumulative energization time counter reaches 65535, it starts from 0 again. The number of times the actual
operation time counter reaches 65535 can be checked with Pr.564.
• Setting "0" in Pr.171 clears the actual operation time meter.
NOTE
• The actual operation time does not increase if the cumulative running time before power OFF is less than an hour.
• Once "0" is set in Pr.171, the setting of Pr.171 is always turned to "9999" afterwards. Setting "9999" does not clear the
actual operation time meter.
 Hiding the decimal places for the monitors (Pr.268)
• The numerical figures after a decimal point displayed on the operation panel may continuously fluctuate during analog
input, etc. The decimal places can be hidden by selecting the decimal digits with Pr.268.

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.
 Negative output selection for monitoring (Pr.290)
• Negative output is available for FR Configurator2 or the trace function.

*1 The following communication does not support the negative output.
RS-485 communication (Mitsubishi inverter protocol, MODBUS RTU, BACnet), LONWORKS communication (FR-A8NL), and SLMP
communication
*2 Under the condition that the high-speed sampling and the negative output are selected for FR Configurator2, the display range of the output
frequency (Monitor No.1) is -300.00 Hz to 300.00 Hz. A value outside the range is clamped at -300.00 Hz or 300.00 Hz. Under the same condition,
the display range of the running speed (Monitor No.6) is -30000 r/min to 30000 r/min. A value outside the range is clamped at -30000 r/min or
30000 r/min. During the trace sampling, the same display ranges are applied. A value outside the ranges is clamped.

5.8 (M) Monitor display and monitor output signal
No function
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.
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.
