Note: 1. The monitoring of items marked × cannot be selected.
2. By setting "0" in Pr. 52, the monitoring of "output frequency to alarm display" can be selected in
sequence by the
3. *"Frequency setting to output terminal status" on the PU main monitor are selected by "other
monitor selection" of the parameter unit (FR-PU04).
4. **The load meter is displayed in %, with the current set in Pr. 56 regarded as 100%.
5. The motor torque display is valid only in the advanced magnetic flux vector control mode.
6. The actual operation time displayed by setting "23" in Pr. 52 is calculated using the inverter
operation time. (Inverter stop time is not included.) Set "0" in Pr. 171 to clear it.
7. When Pr. 53 = "0", the level meter display of the parameter unit can be erased.
8. By setting "1, 2, 5, 6, 11, 17 or 18" in Pr. 53, the full-scale value can be set in Pr. 55 or Pr. 56.
9. The cumulative energization time and actual operation time are calculated from 0 to 65535 hours,
then cleared, and recalculated from 0.
When the operation panel (FR-DU04) is used, the display shows "----" after 9999 or more hours
have elapsed. Whether 9999 or more hours have elapsed or not can be confirmed on the
parameter unit (FR-PU04).
10.The actual operation time is not calculated unless the inverter has operated for longer than one
hour continuously.
11. When the operation panel (FR-DU04) is used, the display unit is Hz, V or A only.
12.Position pulse and orientation status function when the FR-A5AP option is used. If the option is
not used, "19" or "22" may be set in Pr. 52 and the value displayed remains "0" and the function is
invalid.
13.The cumulative power is accumulated from 0 to 99999kWh, then cleared, and accumulated again
from 0.
When the operation panel (FR-DU04) is used, the display shows "----" after 9999 or more hours
have elapsed. Whether 9999 or more hours have elapsed or not can be confirmed on the
parameter unit (FR-PU04).
REMARKS
For the monitor set in Pr. 52, its display position depends on the set value.
