Basic Functions
3.3.5 Acceleration/deceleration time (Pr. 7, Pr. 8)
<Setting>
•Use Pr. 7 to set the acceleration time required to reach the set frequency of 60Hz
from 0Hz.
•Use Pr. 8 to set the deceleration time required to reach 0Hz from 60Hz.
Used to set motor acceleration/
deceleration time.
Set a larger value for a slower
speed increase/decrease or a
smaller value for a faster speed
increase/decrease.

Range
7 Acceleration time 5s 0 to 999s
8 Deceleration time 5s 0 to 999s
CAUTION
1. If the Pr. 7/Pr. 8 setting is "0", the acceleration/deceleration time is 0.04s.
2. If the acceleration/deceleration time is set to the shortest value, the actual
motor acceleration/deceleration time cannot be made shorter than the
shortest acceleration/deceleration time which is determined by the
mechanical system's J (moment of inertia) and motor torque.
