Monitor display for operation panel (Pr.774 to Pr.776)
• The monitor displayed at power ON is the first monitor (the converter output voltage monitor in the initial setting). Display
the monitor you want to display on the first monitor and hold down
for 1 second. To monitor the converter output
voltage, display the screen of converter output voltage and hold down
for 1 second.
• The monitor to be displayed is set using
Pr.774
for the first screen,
Pr.775
for the second screen, and
Pr.776
for the third
screen.
Operation panel setting dial push display (Pr.992)
• Use
Pr.992
to select the monitor that appears when the setting dial on the operation panel is pushed. The converter output
voltage value is displayed in the initial status (
Pr.992
= "8").
Monitoring I/O terminals on the operation panel (Pr.774 to Pr.776)
• When
Pr.774 to Pr.776
= "55", the I/O terminal state can be monitored on the operation panel.
• The corresponding LED segment is ON when a terminal is ON, and the LED segment is OFF when a terminal is OFF. The
center LED segments are always ON.
• On the I/O terminal monitor (
Pr.774 to Pr.776
= "55"), the upper LEDs denote the input terminal status, and the lower LEDs
denote the output terminal status.
Monitoring and resetting cumulative power (Pr.170, Pr.891)
• When the cumulative power is monitored (
Pr.774 to Pr.776
= "25"), the input power monitor value is added up and is
updated in 100 ms increments. (The values are saved in EEPROM every hour.)
• Increments and ranges of monitoring on the operation panel (FR-DU08) or via communication (RS-485 communication)
are as follows.
*1
Energy is measured in the range of 0 to 99999.99 kWh, and displayed in five digits. After the watt-hour meter (cumulative power counter) reaches
"999.99" (999.99 kWh), the meter displays values in 0.1 increments such as "1000.0" (1000.0 kWh).
• The decimal point position on the watt-hour meter can be shifted to left. The number of digits to be shifted is equal to the
setting of
Pr.891 Cumulative power monitor digit shifted times
. For example, when
Pr.891
= "2", the cumulative power
value 1278.56 kWh is displayed as 12.78 (in 100 kWh increments) on the operation panel, or displayed as 12 on a display
used for monitoring via communication.
