Settings 0.1~3600.0 Sec Factory Setting: 10.0/60.0
Factory setting for 30HP and higher models is 60.0 seconds.
Acceleration time is the time required for the AC drive to ramp from 0 Hz to its Maximum
Output Frequency (Pr.1-00). Deceleration time is the time required for the AC drive to
decelerate from Maximum Output Frequency (Pr.1-00) down to 0 Hz.
An Acceleration or Deceleration time that is too quickly, may cause the AC drives protection
features to enable (over-current stall prevention during Accel 06-01 or over-voltage stall
prevention 06-00). If this occurs, the actual Accel/Decel time will be longer than this setting.
Warning: An acceleration or deceleration that is too quickly, may cause excess loads on the
AC drive and may permanently damage the drive.
If you want to decelerate the AC drive in short time period, we recommend adding an external
braking module and braking resistor.
You can set 1st to 4th Accel/Decel time via multi-function input terminals 04-00 to 04-03.
