Load characteristics setting (Pr. 1481 to Pr. 1487)
●
Use Pr. 1481 to Pr. 1485 to set the reference value of load characteristics.
●
Use Pr. 1486 "Load characteristics maximum frequency" and Pr. 1487 "Load characteristics mini-
mum frequency" to set the output frequency range for load fault detection.
Automatic measurement of the load characteristics reference
(Load characteristics measurement mode) (Pr. 1480)
●
Setting Pr. 1480 "Load characteristics measurement mode" = "1" enables automatic measurement
of the load characteristics reference. (Load characteristics measurement mode)
●
Use Pr. 1486 and Pr. 1487 to set the frequency band for the measurement, and set Pr. 1480 = "1".
After setting, when the inverter is started, the measurement starts.
●
The automatically measured load characteristics reference is written in Pr. 1481 to Pr. 1485.
●
After the measurement is started, read Pr. 1480 to display the status of the measurement. If "8"
appears in the tens place, the measurement has not properly completed.

Setting of the load characteristics and output frequency range
NOTES
Perform measurement under actual environment with the motor connected.
Set the Pr. 1487 "Load characteristics minimum frequency" higher than the Pr. 13 "Starting fre-
quency".
