Measurement start
Fig. 5-146:
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.
