P10. This parameter is used to determine the time required for the AC
drive to ramp from 0 Hz to its Maximum Output Frequency (P03). The
rate is linear unless the S-Curve (P14) is Enabled .
P11. This parameter is used to determine the time required for the AC
drive to decelerate from the Maximum Output Frequency (P03) down
to 0 Hz. The rate is linear unless the SCurve (P14) is
P12 and P13: Provide an additional Accel/Decel time although Time 1
is the default. A Multi-Function input terminal must be programmed
to select Accel/ or Decel/ Time 2 and the terminal must be closed to
select Accel/Decel Time 2 (See P38 to P42).
In the below diagram, suppose the Maximum Output Frequency is 50 Hz
(Master Freq),Minimum Output Frequency (star t-up) is 1.5 Hz, and
accel/decel time 1 is 10 seconds. The actual time for the AC drive to
accelerate from start-up to 50 Hz is 9.7 seconds (deceleration time is
also 9.7 seconds), can be determined by the formula.

Settings

This parameter is used whenever the motor load needs to be accelerated
or decelerated smoothly. The desired accel/decel effect is selectable
from 0 to 7, in which the larger the number, the greater the effect
achieved. If the default value of P111 Deceleration S Curve is unchanged
("0"), then P14 sets both acceleration and deceleration S-Curves. If
P111 is set to any value other than"0", then P14 will set the acceleration
S-Curve and P111 will set the deceleration S-Curve.
