Set the number of times to shift the
cumulative power monitor digit
Clamp the monitoring value at
maximum.
No shift
Clear 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 122) during commercial
power supply operation.
Set the motor capacity (pump
0.1 to 55kW
capacity). Set when calculating
power saving rate, average power
