3.4.10 Measuring load factor
-- Menu #9 "Load Factor Measurement" --
Menu #9 "Load Factor Measurement" in Programming mode allows you to measure the maximum output
current, the average output current, and the average braking power. There are two modes of measurement:
"hours set" and "start to stop" modes. In the former mode, the measurement takes place for a specified length of
time; in the latter mode, the measurement takes place from the start of running to the stop.
If the "start to stop" mode is entered while the inverter is running, the measurement takes place until it
is stopped. If the "start to stop" mode is entered while the inverter is stopped, the measurement will
take place from the next start of running until it is stopped.
