Chapter 5 Description of Parameter Settings

& The accel/decel time 2 determines the time for the AC drive to accel/decel

from 0Hz to Maximum Output Frequency (Pr.1-00) (accel/decel time 1 is the

default). A Multi-Function Input terminals must be programmed to select

accel/decel time 2 and the terminals must be closed to select accel/decel

time 2. See Pr.4-04 to Pr.4-08.

& In the diagram shown below, the accel/decel time of the AC drive is the time

between 0 Hz to Maximum Output Frequency (Pr.1-00). Suppose the

Maximum Output Frequency is 60 Hz, start-up frequency (1-05) is 1.0 Hz,

and accel/decel time is 10 seconds. The actual time for the AC drive to

accelerate from start-up to 60 Hz is 9.83 seconds and the deceleration time

is also 9.83 seconds.
