Motor Cumulative Run Time (Motor 0 to 8)
In the pump control, each motor cumulative run time (J480 to J488) is cumulated. The motor
cumulative run time can be used for maintenance plan.
The motor cumulative run time is counted when the gate is turned ON and the dew
condensation prevention function is not operated.
This is counted even during commercial operation due to the output signal, “M
_L”
from the
inverter.
The cumulative run time is cumulated in the range from 0 to 65,535 hours and reset to zero as
it exceeds 65,535 hours, and then the time is cumulated continually. For the display of
cumulative run time, 1 hour is displayed as 1 hours in the keypad.
The cumulative run time can be specified to any value from the keypad. The initial time of
replacing machine parts or inverter can be specified to any value.
The chart below indicates cumulative operating times and corresponding motor numbers for
each pump control mode selection (J401) setting.
