Energy Saving Monitor (Pr. 891 To Pr. 899) - Mitsubishi Electric FR-A720-0.4K Instruction Manual

Energy saving operation and energy saving monitor

4.19.2 Energy saving monitor (Pr. 891 to Pr. 899)

From the power consumption estimated value during commercial power supply operation, the energy saving
effect by use of the inverter can be monitored/output.

Clear the monitor value when it
exceeds the maximum value.
Set the load factor for commercial
power-supply operation. Multiplied by
