Set the desired Accel/Decel time at ACC/dEC in Drive group.
If H70 is set to 0 {Max frequency}, Accel/Decel time is the time that takes to reach the max
freq from 0 Hz.
Desired Accel/Decel time unit is settable at the H71.
Accel/Decel time is set based on F21 – [Max frequency]. For instance, if F21 is set to 60Hz,
Accel/Decel time 5 sec, and run frequency 30Hz, time to reach 30Hz would be 2.5 sec.
