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.
Pr.01-45=0: 0.00~600.00 seconds
Pr.01-45=1: 0.00~6000.00 seconds
