Setting Frequency References 1 to 4
3-5-2 Setting Acceleration and Deceleration Times
• The acceleration time and the deceleration time are set separately.
• The acceleration time is the time required to accelerate from 0% to 100% of the maximum output
frequency (P06), and the deceleration time is the time required to decelerate from 100% to 0% of
the maximum output frequency.
• The setting unit for the acceleration and deceleration times is 0.1 s for less than 100 s, and 1 s for
100 s or more.
• If the load inertia is high, the acceleration and deceleration times must be increased. For details,
refer to 7-1 Selecting the Inverter at the end of this manual.
• The acceleration/deceleration time between 0 and the frequency reference is calculated with the
following formula.
Acceleration/deceleration time = (Acceleration/deceleration time setting)
×
(Frequency reference)
÷
(Maximum output frequency setting)
Note When accelerating from a stopped condition, the starting DC breaking time must be added.
