5-13 Soft Start
Function
• This function accelerates and decelerates the Servomotor in the set acceleration and deceleration
times.
• You can set the acceleration and deceleration independently of each other using the trapezoidal
acceleration and deceleration curve.
• The soft start processes speed command input (REF) or internally set speed control switching to
reduce impact during acceleration and deceleration.
• This function is effective for simple positioning and speed switching operations.
• Do not use this function for a position controller with an acceleration/deceleration function.
Parameters Requiring Settings
• If the soft start function is not used, set this parameter to 0 (default setting).
• The actual acceleration and deceleration time is as follows:
Parameter
No.
