Parameter Monitor display and monitor output signals
FR-D700 SC EC 6 - 113
Frequency setting to output terminal status on the PU main monitor are selected by "other
monitor selection" of the parameter unit (FR-PU04/FR-PU07).
The cumulative energization time and actual operation time are accumulated from 0 to 65535
hours, then cleared, and accumulated again from 0.When the operation panel is used, the
time is displayed up to 65.53 (65530h) on the assumption that 1h = 0.001, and thereafter,
it is added up from 0.
Actual operation time is not accumulated when the cumulative operation time is less than
1h until turning off of the power supply.
When using the parameter unit (FR-PU04/FR-PU07), "kW" is displayed.
Since the panel display of the operation panel is 4 digits in length, the monitor value of more
than "9999" is displayed "----".
Larger thermal value between the motor thermal and transistor thermal is displayed.
A value other than 0% is displayed if the ambient temperature (heatsink temperature) is high
even when the inverter is at a stop.
