 The Acceleration Time is used to determine the time required for the AC motor drive to ramp from
0Hz to Maximum Output Frequency (Pr.01-00).
 The Deceleration Time is used to determine the time require for the AC motor drive to decelerate
from the Maximum Output Frequency (Pr.01-00) down to 0Hz.
 The Acceleration/Deceleration Time is invalid when using Pr.01-44 Optimal
Acceleration/Deceleration Setting.
 The Acceleration/Deceleration Time 1, 2, 3, 4 are selected according to the Multi-function Input
Terminals settings. The factory settings are Accel./Decel. time 1.
 When enabling torque limits and stalls prevention function, actual accel./decel. time will be longer
than the above action time.
 Please note that it may trigger the protection function (Pr.06-03 Over-current Stall Prevention
during Acceleration or Pr.06-01 Over-voltage Stall Prevention) when the setting of accel./decel.
time is too short.
 Please note that it may cause motor damage or drive protection enabled due to over current during
acceleration when the setting of acceleration time is too short.
 Please note that it may cause motor damage or drive protection enabled due to over current during
deceleration or over-voltage when the setting of deceleration time is too short.
 It can use suitable brake resistor (see Chapter 06 Accessories) to decelerate in a short time and
prevent over-voltage.
 When enabling Pr.01-24~Pr.01-27, the actual accel./decel. time will be longer than the setting.
