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 the I/O terminal monitor (Pr. 52 = "55"), the upper LEDs denote the input terminal status and the lower the output
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 value is stored in EEPROM in 1h increments.)
The operation panel, parameter unit (FR-PU04/FR-PU07) and communication (RS-485 communication) display
increments and display ranges are as indicated below.
0 to 99.99kWh
100.0 to 999.9kWh
1000 to 9999kWh
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 226
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-PU04/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.
If "0" is written to Pr. 170 and Pr. 170 is read again, "9999" or "10" is displayed.
