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.

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.

Three fixed frequencies can be adjusted. The selection of the fixed frequencies
occurs with the inputs I1 and I2 (terminal X1.4 and X1.5).

If presetting occurs outside of the fixed limits of CP.9 and CP.10, then the
frequency is internally limited.
