6.2.5. Using the Soft Start Function
The soft start function adjusts progressive speed reference input inside
the servo amplifier so that acceleration and deceleration can be as
constant as possible. To use this function, set the following parameters.

Speed Control
In the servo amplifier, a speed reference is smoothed by the acceleration
or deceleration value set in Pn305 or Pn306 to provide speed control.
The soft start function enables smooth speed control when non-
progressive speed references are input or when contact input speed
control is used.
Set both Pn305 and Pn306 to “0” for normal speed control, i.e when the
speed reference does not need to be smoothed.
Set these parameters as follows:
• Pn305: The time interval from the time the motor starts until the
maximum speed is reached.
• Pn306: The time interval from the time the motor is operating at the
maximum speed until it stops.
