►
More precise time unit can be set corresponding to load characteristics as shown below.
►
In SV-iG5H, 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.
