online auto tuning is not activated.
2. For a restart during deceleration or DC injection brake operation, the online auto tuning is not
3. The online auto tuning is invalid for programmed operation or jog operation.
4. When automatic restart after instantaneous power failure is selected, it overrides the online
auto tuning.
5. For use in vertical lift application, examine the use of a brake sequence for brake opening
timing at the start. Though the tuning ends in about a maximum of 500ms after a start, enough
torque is not provided during that period. Therefore, note that the load may drop with gravity.
6. Zero current detection and output current detection are also valid during the online auto
7. The RUN signal is not output during the online auto tuning. The RUN signal switches on at a
8. When programmed operation is selected (Pr. 79 = 5), the online auto tuning is invalid and is
not executed.

but operation will not reflect the tuning results.
