Energy Saving Monitoring - Mitsubishi Electric 800 Series Instruction Manual

11.5

Energy saving monitoring

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

Description
50: Energy saving effect monitoring,
51: Cumulative energy saving monitoring
50: Energy saving effect monitoring
Set the number of times to move the digit of cumulative power
monitored value. The readout peaks out at the upper limit of
readout.
The function of moving the decimal point is not available. The
readout is reset to 0 when it exceeds the upper limit.
Set the load factor for the commercial power supply operation.
The setting is used for calculation of the estimated power
consumption during commercial power supply operation by
being multiplied by the power consumption rate
Set the motor capacity (pump capacity). Setting this parameter
is required for calculating the rate of saved power, the rate of
average energy saving, and the commercial power.
Discharge damper control (fan)
Inlet damper control (fan)
Valve control (pump)
Commercial power supply drive (fixed value)
Consider the commercial power as 100%.
Consider the power set in Pr.893 as 100%
No function
Set the power unit cost. Setting this parameter is required for
displaying the energy cost savings in the energy saving
monitoring.
No function
The time period for averaging is 30 minutes.
Set the number of hours for averaging.
No function
Clear the cumulative monitor value
Hold the cumulative monitor value
Continue accumulation (upper limit communication data is 9999)
Continue accumulation (upper limit communication data is
65535)
Setting this parameter is required for calculating the annual
energy saving. Set an annual operating rate (considering a 24-
hours-a-day and 365-days-a-year operation as 100%).
