● When offline auto tuning ends, press STOP/RESET key on the operation panel during PU operation.
For External operation, turn OFF the start signal (STF signal or STR signal).
This operation resets the offline auto tuning, and the PU's monitor display returns to the normal
indication.
(Without this operation, next operation cannot be started.)
NOTES The motor constants measured once in the offline auto tuning are stored as parameters and their
data are held until the offline auto tuning is performed again. However, the tuning data is cleared
by performing all parameter clear.
Changing Pr. 71 after tuning completion will change the motor constant. For example, if Pr. 71 =
"8093" is set after tuning is performed with Pr. 71 ="8090", the tuning data becomes invalid. Set
Pr. 71 = "8090" again for using the tuning data.
