Switching Acceleration and Deceleration Time Automatically
Use this setting when you want to switch acceleration/deceleration time automatically using the set frequency.
When the output frequency reaches the set value in C1-11, the Inverter switches the acceleration/deceleration
time automatically as shown in the following diagram.
Set C1-11 to a value other than 0.0 Hz. If C1-11 is set to 0.0 Hz, the function will be disabled.

Adjusting Acceleration and Deceleration Time Using an Analog Input
If you set H3-09 (Multi-function Analog Input Terminal A2 Function Selection) or H3-05 (Multi-function
Analog Input Terminal A3 Function Selection) to 5 (acceleration/deceleration time gain), you can adjust the
acceleration/deceleration time using terminal A2's input voltage.
The Inverter's acceleration time when the acceleration time has been set in C1-01 is as follows:
Acceleration time = C1-01 set value x acceleration/deceleration time gain

When output frequency ≥ C1-11, acceleration and deceleration are performed using
Acceleration/deceleration Time 1 (C1-01, C1-02).
When output frequency < C1-11, acceleration and deceleration are performed using
Acceleration/deceleration Time 4 (C1-07, C1-08).
