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 run freq (Currently operating freq.).
When H70 and Accel time are set to 1 {Delta frequency} and 5 sec, respectively,
(A zone: run freq 10 Hz applied first, B zone: Operating via 10 Hz, different run freq is not issued
C: 30Hz Run freq (in this case, Target freq) issued while 10 Hz run freq is applied. But the preset
accel time 5 sec is maintained. )
