Acceleration time
Deceleration time
S-curve time
The parameter determines the time needed to accelerate from 0 Hz to
100 Hz. The actual acceleration time is proportional to the frequency
change.
100 Hz
–––––– x actual acceleration time = CP.12
delta f
Adjustment range:
Resolution:
Factory setting:
Example: actual acceleration time = 5s; the drive should accelerate from
10 Hz to 60 Hz. delta f = 60 Hz - 10 Hz = 50 Hz
CP.12 = (100 Hz / 50 Hz) x 5 s = 10 s
The parameter determines the time needed to decelerate from 100 Hz to
0 Hz. The actual deceleration time is proportional to the frequency change.
100 Hz
–––––– x actual deceleration time = CP.13
delta f
Adjustment range:
Resolution:
Factory setting:
At -1 deceleration time –> see CP.12 (Display: "=Acc")!
Example: actual deceleration time = 5s; the drive should decelerate from
60 Hz to 10 Hz. delta f = 60 Hz - 10 Hz = 50 Hz
CP.12 = (100 Hz / 50 Hz) x 5 s = 10 s
For some applications it is of advantage when the drive starts and stops
jerk-free. This is achieved through a straightening of the acceleration and
deceleration ramps. The straightening time, also called S-curve time, can
be adjusted with CP.14.
Adjustment range:
Resolution:
Factory setting:
In order to drive defined ramps with activated S-curve time,
the acceleration and deceleration times (CP.12 and CP.13)
must be adjusted higher than the S-curve time (CP.14).
