50:Power saving monitor
Set the number of times to shift the
cumulative power monitor digit
(Clamps the monitor 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 179)
during commercial power supply
operation.
The motor capacity (pump capacity).
Set when calculating power saving
rate, average power saving rate,
commercial operation power.
