Differs according to capacities. (FR-A820-03160(55K) or lower, FR-A840-01800(55K) or lower/
FR-A820-03800(75K) or higher, FR-A840-02160(75K) or higher)
When the output current is less than the specified current level (5% of the rated inverter current),
the output current is monitored as 0 A. Therefore, the monitored value of an output current and
output power may be displayed as "0" when using a much smaller-capacity motor compared to
the inverter or in other instances that cause the output current to fall below the specified value.
Setting of Pr. 1018 "Monitor with sign selection" is required.
The setting is available only for standard models.
The setting is available only with terminal AM (Pr. 158).
