Energy Saving Operation And Energy Saving Monitor; Energy Saving Monitor (Pr. 891 To Pr. 899) - Mitsubishi Electric FR-B-750 to 75K Instruction Manual

Energy saving operation and energy saving monitor

4.15 Energy saving operation and energy saving monitor
Purpose
How much energy can be saved

4.15.1 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.

Clamps the monitoring value at maximum.
No shift
Clears the monitor value when it exceeds
the maximum value.
Set the load factor for commercial power-
supply operation. Multiplied by the power
consumption rate (page 163) during
commercial power supply operation.
