Speed Search (Speed
Estimation Type)
Srch Im Lvl2
Sets the amount of output current during Speed Estimation Speed Search as a
coefficient for the no-load current (output current during Speed Search is
automatically limited by the drive rated current).
Increase this setting value in increments of 0.1 if the drive fails to perform
Speed Estimation.
Default: 1.0
