Set the desired Accel/Decel time at ACC/dEC in Drive group.
If H70 in function group 2 is set to 0 (Max frequency), Accel/Decel time is the time that takes to reach
the max freq from 0 Hz, it does not relate with the operation frequency.
Desired Accel/Decel time unit is settable at the H71.
Frequency reference for Accel/Decel (H70)is set to 0 (Max frequency), if Max frequency(F21) is set to 60Hz,
Accel/Decel time 5 sec, when run frequency is set to 30Hz, time to reach 30Hz would be 2.5 sec.
Corresponding to load property, when more precious Accel/Decel time is desired, the setting unit can be
changed as follows.
In LTVF-Cx2000, 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., with changes as follows:
