z

Acceleration/deceleration time (Pr. 7, Pr. 8, Pr. 20, Pr. 21, Pr. 44, Pr. 45, Pr. 110, Pr. 111)

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"
Pr. 110 "third acceleration/deceleration time"
Pr. 111 "third deceleration time"
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.

·
Use Pr. 21 to set the acceleration/deceleration time and minimum setting increments:
Set value "0" (factory setting)........ 0 to 3600 seconds (minimum setting increments: 0.1 second)
Set value "1".................................. 0 to 360 seconds (minimum setting increments: 0.01 second)
·
Use Pr. 7, Pr. 44 and Pr. 110 to set the acceleration time required to reach the frequency set in Pr. 20 from
0Hz.
·
Use Pr. 8, Pr. 45 and Pr. 111 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, and Pr. 110 and Pr. 111 are valid when the X9 signal
is on. When both RT and X9 are on, Pr. 110 and Pr. 111 are valid.
·
Use any of Pr. 180 to Pr. 186 to assign the terminal used to input the X9 signal.
·
Set "9999" in Pr. 45 and Pr. 111 to make the deceleration time equal to the acceleration time (Pr. 44, Pr. 110).
·
When "9999" is set in Pr. 110, the function is made invalid.
