Pr.10. This parameter is used to determine the time required for the AC drive to ramp from 0
Hz to its Maximum Output Frequency (Pr.03). The rate is linear unless the S-Curve (Pr.14) is
"Enabled".
Pr.11. This parameter is used to determine the time required for the AC drive to decelerate
from the Maximum Output Frequency (Pr.03) down to 0 Hz. The rate is linear unless the S-
Curve (Pr.14) is "Enabled".
Pr.12 and Pr.13: 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 Pr.38 to Pr.42).
In the below diagram, suppose the Maximum Output Frequency is 60 Hz (Master Freq),
Minimum Output Frequency (start-up) is 1.0 Hz, and accel/decel time 1 is 10 seconds. The
actual time for the AC drive to accelerate from start-up to 60 Hz is 9.83 seconds (deceleration
time is also 9.83 seconds), can be determined by the formula.
