7-3 Description of Functions
(Example) In case of change from 20Hz to 50Hz acceleration in 1st acceleration/deceleration,
F1011=50[Hz]: The setting value of acceleration/deceleration reference time.
F1012=5[s]: The setting value of acceleration time.
F1022=50[%]: S-shaped curve with medium-curvature start.
F1023=50[%]: S-shaped curve with medium-curvature arrival.
F1024=0[%]: The slope of middle part is the same with that in linear acceleration.

●
Examples of S-shaped curves combined according to the set values are shown below. In each of these examples,
acceleration/deceleration reference time and acceleration/deceleration time settings are set to the same value.
F1011=50[Hz] / F1012=5[s] / F1016=5[s]
Example 1) F1022=100 F1023=100 F1024=100 F1025=100 F1026=100 F1027=100

The arrival time is equal to that in linear acceleration / deceleration. However, since the slope of the middle
portion is twice as that in linear acceleration/deceleration mode, the current limiting function may operate
depending on the magnitude of the load inertia.

Example 2) F1022=100 F1023=100 F1024=100 F1025=100 F1026=100 F1027=100.

The curvature of the S-shaped acceleration/deceleration's start portion and end portion become maximum, and
the slope of the S-shaped acceleration/deceleration‘s middle portion becomes the same as that in the linear
acceleration/deceleration mode.

Acceleration Deceleration Time
Example 3) F1022=0 F1023=0 F1024=0 F1025=0 F1026=0 F1027=0.
The result is the same with that in the linear acceleration/deceleration mode.
