More precise time unit can be set corresponding to load characteristics as shown below.

In SV-iG5A, number display is available up to 5. Therefore, if time unit is set to 0.01 sec, Max
Accel/Decel time would be 600.00 sec.


Accel/Decel time is set at the ACC/dEC .

If you set H70 to 1 {Delta frequency}, Accel/Decel time is the time that takes to reach a
target freq from constant run freq (Current operating freq.).

When H70 and Accel time are set to 1 {Delta frequency} and 5 sec, respectively,

The below graph in Section A shows the change in operating frequency when target frequency is
set to 10Hz at first and then changed to 30Hz.
