tion time increments"
(1) Confirmation of acceleration time setting range and
minimum setting increments
Use Pr. 21 "accelerationldeceleration time increments" to
set the acceleration time setting range and minimum set-
ting increments. Before setting the acceleration time, the
set value must be checked.

Set value "1" 0 to 360 seconds

(2) Setting of acceleration time
In acceleration time (Pr. 7),
set a period of time required
to reach the accelerationlde-
celeration reference
frequency (Pr. 20) from OHz.
Set a longer time to acceler-
ate more slowly; and a
shorter time to accelerate
Accelerati6n

more rapidly. (Note)
Vote: 1. In only S-pattern accelerationldeceleration A (see page 77), the set
time is a period of time required to reach the base frequency (Pr. 3).
2. If Pr. 20 (accelerationldeceleration reference frequency) setting is
changed, the set values of calibration Pr. 903 and Pr. 905 (frequency
setting signal gain) remain unchanged. To adjust the gains, adjust
calibration Pr. 903 and Pr. 905.
3. When the set value of Pr. 7 is "0" the acceleration time is set to 0.04
