Setting Of Acceleration/Deceleration Time And Acceleration/ Deceleration Pattern; Setting Of The Acceleration And Deceleration Time (Pr. 7, Pr. 8, Pr. 20, Pr. 21, Pr. 44, Pr. 45, Pr. 147) - Mitsubishi Electric FR-E720-008 Instruction Manual

Setting of acceleration/deceleration time and acceleration/ deceleration pattern

4.8 Setting of acceleration/deceleration time and acceleration/
deceleration pattern
Purpose
Motor acceleration/deceleration
time setting
Starting frequency
Set acceleration/deceleration
pattern suitable for application
Automatically set optimum
acceleration/deceleration time.
4.8.1 Setting of the acceleration and deceleration time
(Pr. 7, Pr. 8, Pr. 20, Pr. 21, Pr. 44, Pr. 45, Pr. 147)
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.
For the acceleration time at automatic restart after instantaneous power failure, refer to Pr. 611 Acceleration time at a
restart (page 161).
