(3) Operation panel I/O terminal monitor (Pr. 52)
When Pr. 52 = "55", the I/O terminal status can be monitored on the operation panel.
The I/O terminal monitor is displayed on the third monitor.
The LED is ON when the terminal is ON, and the LED is OFF when the terminal is OFF. The center line of LED is always
ON.
On the I/O terminal monitor (Pr. 52 = "55"), the upper LEDs denote the input terminal status and the lower the output
terminal status.

(4) Cumulative power monitor and clear (Pr. 170, Pr. 891)
On the cumulative power monitor (Pr. 52 = "25"), the output power monitor value is added up and is updated in 100ms
increments. (The values are saved in EEPROM every hour.)
The operation panel, parameter unit (FR-PU07) and communication (RS-485 communication) display increments and
display ranges are as indicated below.


Power is measured in the range of 0 to 9999.99kWh, and displayed in 4 digits.
When the monitor value exceeds "99.99", a carry occurs, e.g. "100.0", so the value is displayed in 0.1kWh increments.

Power is measured in the range of 0 to 99999.99kWh, and displayed in 5 digits.
When the monitor value exceeds "999.99", a carry occurs, e.g. "1000.0", so the value is displayed in 0.1kWh increments.

In monitoring with communication, cumulative power is displayed in 1kWh increments. And cumulative power 2 is displayed in 0.01kWh. (Refer to page 191
for communication.)
The monitor data digit can be shifted to the right by the number of Pr. 891 settings.
For example, if the cumulative power value is 1278.56kWh when Pr. 891 = "2", the operation panel display or parameter
unit (FR-PU07) display is 12.78 (display in 100kWh increments) and the communication data is 12.
If the maximum value is exceeded at Pr. 891 = "0 to 4", the power is clamped at the maximum value, indicating that a digit
shift is necessary. If the maximum value is exceeded at Pr. 891 = "9999", the power returns to 0 and is recounted.
If the maximum value is exceeded at Pr. 891 = "9999", the power returns to 0 and is recounted.
Writing "0" in Pr. 170 clears the cumulative power monitor.
REMARKS
 If "0" is written to Pr. 170 and Pr. 170 is read again, "9999" or "10" is displayed.
