 Use S Curve parameters where a smooth acceleration or deceleration action is required, this will
prevent possible damage to driven machines by sudden acceleration/deceleration.

※ Note:
 Regardless of the stall prevention period, actual acceleration and deceleration time =preset
acceleration / deceleration time + S curve time.
 Please set the required individual S curve times in the parameters (11-04~11-07)
 When S curve time (11-04~11-07) is set as 0, the S curve function is disabled.
 The calculation of S curve time is based on the Maximum output frequency of motor (01-02), Please
refer to the parameter (00-14/00-15/00-16/00-17).

Skip frequency parameters can be used to avoid mechanical resonance in certain applications.
Example：11-08=10.00(Hz); 11-09=20.00(Hz); 11-10=30.00(Hz); 11-11=2.00(Hz).
10Hz ±2Hz=8~12Hz
20Hz ±2Hz=18~22Hz Skip frequency
30Hz ±2Hz=28~32Hz
