Note 3: Acceleration/deceleration time varies depending on fluctuations in current value, even with
the same motor.
Note 4: The automatic optimum acceleration/deceleration setting is enabled only during V/f control.
When sensorless vector control is selected, the Inverter performs normal operation.
Note 5: If the jogging operation is performed when the automatic operation is selected, the Inverter
performs automatic acceleration, which is different from normal jogging operation.
Note 6: When the applied load is larger than the rating, deceleration time may be prolonged.
Note 7: If acceleration and deceleration are frequently repeated, the Inverter may trip.
Note 8: When the internal braking circuit is used, or when the regenerative braking unit is externally
installed, the motor cannot stop within the specified deceleration time because of braking
resistance. In this case, do not use the automatic optimum acceleration/deceleration
function.
Note 9: When using a lower rank motor size than specified for the Inverter, enable the overload limit
function (b021), and set the overload limit level (b022) to 1.5 times the rated current of the
motor.
2-step Acceleration/Deceleration Function
• By setting this function, you can change the acceleration/deceleration time during acceleration/
deceleration.
* To switch to the 2nd/3rd control, allocate 08 (SET)/17 (SET3) to the desired multi-function input and then turn it
on.
