NOTES Online auto tuning does not operate if the MRS signal is input, if the preset speed is less
than the Pr. 13 "Starting frequency" (V/f control or advanced magnetic flux vector control), or
if the starting conditions of the inverter are not satisfied, e.g. inverter error.
Online auto tuning does not operate during deceleration or at a restart during DC brake
operation.
Online auto tuning is invalid for jog operation.
Automatic restart after instantaneous power failure overrides when automatic restart after
instantaneous power failure is selected. (Start-time online auto tuning is not performed at
frequency search.)
Perform online auto tuning at a stop with the X28 signal when using automatic restart after
instantaneous power failure together.(Refer to the following for details.).
Zero current detection and output current detection are valid during online auto tuning.
The RUN signal is not output during online auto tuning. The RUN signal turns on at a start.
If the period from an inverter stop to a restart is within 4s, start-time tuning is performed but
the tuning results are not reflected.
