Mitsubishi Electric FR-A800, Instruction Manual

Page: 523 / 1042

Parameters (M) Monitor display and monitor output signal
FR-A800 5 - 343
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.
