Acceleration/Deceleration Time Setting

• Set the motor acceleration/deceleration time.
• The set time here is the acceleration/deceleration time from 0 Hz to the maximum frequency. The
actual acceleration/deceleration time varies depending on the frequency reference value.
• This parameter is for setting the time constant of the primary delay filter with respect to the output
frequency during acceleration/deceleration when V/f control (F42/A14 = 0 to 3) is selected. Set this
parameter when an overshoot or undershoot occurs when the frequency arrives at the target fre-
quency or the rotation of the motor stops and this causes mechanical problems. Setting a large val-
ue stabilizes the output frequency but worsens response.

[DI1] to [DI7].
Additional Information
When a short deceleration time is set, the regenerative amount that is fed back at deceleration
increases. When the regenerative amount exceeds the allowable capacity of the inverter, either
the deceleration time is extended by the setting of Anti-regenerative Control Function Selection
(H69), or overvoltage (OU2) is detected. To shorten the deceleration time, use the regenerative
braking function. For details on the regenerative braking function, refer to 5-12 Regenerative
Braking Function on page 5-75.
