Pr. 7 "acceleration time"

Pr. 8 "deceleration time"

Pr. 20 "acceleration/deceleration reference frequency"

Pr. 21 "acceleration/deceleration time increments" Pr. 44 "second acceleration/deceleration time" Pr. 45 "second deceleration time"

Related parameters

Pr. 3 "base frequency"

Pr. 29 "acceleration/deceleration pattern"

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.

<Setting>

•Use Pr. 21 to set the acceleration/deceleration time and minimum setting increments:

Set value "0" (factory setting)	0 to 3600 s (minimum setting increments: 0.1 s)
Set value "1"	0 to 360 s (minimum setting increments: 0.01 s)

•Use Pr. 7 and Pr. 44 to set the acceleration time required to reach the frequency set in Pr. 20 from 0Hz.

•Use Pr. 8 and Pr. 45 to set the deceleration time required to reach 0Hz from the frequency set in Pr. 20.

•Pr. 44 and Pr. 45 are valid when the RT signal is on.

•Set "9999" in Pr. 45 to make the deceleration time equal to the acceleration time Pr. 44.
