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 quick, 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 quick, 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 to add an
external brake module and brake resistor.
You can set 1

Accel/Decel time via multi-function input terminals 04-00 to 04-07.
