● While measuring automatically, the During load characteristics measurement signal (Y213) is
output. For the Y213 signal, assign the function by setting "213 (positive logic)" or "313 (negative
logic)" in any of Pr. 190 to Pr. 196 (output terminal function selection).
● Setting "8888" in Pr. 1481 to Pr. 1485 enables fine adjustment of load characteristics. When setting
Pr. 1481 to Pr. 1485 = "8888" during operation, the load status at that point is set in the parameter.
(Only when the set frequency is within ±2 Hz of the frequency of the measurement point, and SU
signal is in the ON state)

Fig. 5-72:
NOTES Even if the load measurement is not properly completed, the load characteristics fault is detected
based on the load characteristics found by the already-completed portion of the measurement.
During the load characteristics measurement, the load characteristics fault detection is not per-
formed.
During the load characteristics measurement, linear acceleration/deceleration is performed even
if the S-pattern acceleration/deceleration is set.
Changing the terminal assignment using Pr. 190 to Pr. 196 (output terminal function selection)
may affect the other functions. Set parameters after confirming the function of each terminal.
