CP-Parameter for open-loop operation
CP12 acc. time forward
CP13 dec. time forward (-1 = CP12)
Co-domain Setting Description
0.00…300.00 s 5.00 s The parameter determines the time needed to accelerate
from 0 Hz to100 Hz or to decelerate from 100 Hz to 0 Hz.
The actual acceleration-/ deceleration time is proportion-
al to the frequency change (∆f).

time for ∆f
Example A drive shall accelerate from 10Hz to 60Hz in 5s.
∆f = 60 Hz - 10 Hz = 50 Hz
∆t = 5 s
∆t 5 s
CP12 = –––– x 100 Hz = ––––– x 100 Hz = 10 s
∆f 50 Hz
