Settings 0.1 to 600.0 sec / 0.01 to 600.0 sec Factory Setting: 10.0
 Acceleration/deceleration time 1 or 2 can be switched by setting the external terminals MI3~
MI12(MI7~MI12 are optional) to 7 (set Pr.04.05~Pr.04.08 to 7 or Pr.11.06~Pr.11.11 to 7). The
factory settings are acceleration time 1.

The Acceleration Time is used to determine the time required for the AC motor drive to ramp
from 0 Hz to Maximum Output Frequency (Pr.01.00). The Deceleration Time is used to
determine the time required for the AC motor drive to decelerate from the Maximum Output
Frequency (Pr.01.00) down to 0 Hz.
 If the setting of the acceleration/deceleration time is too short, it may trigger the protection
(Pr.06.01(Over-Current Stall Prevention during Accel) or Pr.06.00(Over-Voltage Stall
Prevention)) and make the actual acceleration/deceleration time be larger than this setting.
 If the setting of the acceleration time is too short, it may cause over-current during acceleration
and damage the motor or trigger the protection function.
 If the setting of the deceleration time is too short, it may cause over-current during deceleration
or over voltage of the AC motor drive and damage the motor or trigger the protection function.
 It can use suitable brake resistor to decelerate the AC motor drive in short time and prevent
internal over voltage. Refer to Appendix B for brake resistor.
 When enabling Pr.01.17(Acceleration S-Curve) and Pr.01.18(Deceleration S-Curve), the
actual acceleration/deceleration time will be longer than the setting.
 Related parameters: Pr.01.16(Auto acceleration / deceleration (refer to Accel/Decel time
setting)), Pr.01.17(Acceleration S-Curve), Pr.01.18(Deceleration S-Curve), Pr.04.05(Multi-
function Input Terminal (MI3)), Pr.04.06(Multi-function Input Terminal (MI4)), Pr.04.07(Multi-
function Input Terminal (MI5)) and Pr.04.08(Multi-function Input Terminal (MI6))
