Page 230 • 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 the SU signal is ON).
Page 231  Setting example • The load characteristics are calculated from the parameter setting and the output frequency. • A setting example is as follows. The reference value is linearly interpolated from the parameter settings. For example, the reference when the output frequency is 30 Hz is 26%, which is linearly interpolated from values of the reference 2 and the reference 3.
Page 232 • To prevent the repetitive on/off operation of the signal due to load fluctuation near the detection range, Pr.1492 Load status detection signal delay time / load reference measurement waiting time can be used to set the delay time.
