F6-08
Time proportion of
S-curve start segment
0.0% to (100.0% – F6-09) 30.0%
F6-09
Time proportion of
S-curve end segment
0.0% to (100.0% – F6-08) 30.0%
F6-07 sets acceleration/deceleration mode.
● F6-07 = 0: Linear acceleration/deceleration
Output frequency increases or decreases linearly. The drive provides four groups of
acceleration/deceleration time, selected via F4-00 to F4-08.
● F6-07 = 1: Static S-curve acceleration/deceleration
Output frequency increases or decreases along S curve on the condition that target
frequency is xed. This mode is applied to applications where soft start or stop is required,
such as elevator and conveyor belt.
● F6-07 = 2: Dynamic S-curve acceleration/deceleration
Output frequency increases or decreases along S curve on the condition that target
frequency is changing at real time. This mode is applicable to applications requiring supreme
riding comfort and fast response.
F6-08 and F6-09 define time proportion of start segment and end segment of S-curve
acceleration/deceleration, respectively. They must satisfy F6-08 + F6-09 ≤ 100.0%.
