The parameter determines the time needed in order to decelerate from 100
to 0 Hz. The actual deceleration time is proportional to the frequency change.
actual acceleration time =
Adjustment range:

Factory setting:
Customer adjustment: _______ s
Example: CP. 8 = 10 s ; the drive should decelerate from 60 Hz to 10 Hz
delta f = 60 Hz - 10 Hz = 50 Hz
actual deceleration time = (50 Hz / 100 Hz) x 10s = 5 s
Frequency on which the inverter runs without presetting an analog set
value. Internal limiting of the fixed frequencies CP.11...CP.13.
Adjustment range: 0.0...409.58 Hz

Factory setting:
Customer adjustment: _______ Hz
Frequency on which the inverter runs with maximum analog set value.
Internal limiting of the fixed frequencies CP.11...CP.13.
Adjustment range: 0.0...409.58 Hz

Factory setting:
Customer adjustment: _______ Hz
Three fixed frequencies can be adjusted. The selection of the fixed
frequencies occurs with the terminals X1.4 and X1.5.
Adjustment range:0.0...±409.58 Hz

Factory setting:
Customer adjustment 1: ______ Hz
Customer adjustment 2: ______ Hz
Customer adjustment 3: ______ Hz
If presetting occurs outside of the fixed limits of CP.9 and CP.10, then the
frequency is internally limited.
