Operation
Chapter Section Page Date
When connecting the frequency inverter onto a decelerating motor, an error can be
triggered by the differing rotating field frequencies. With activated speed search the
inverter searches for the actual motor speed, adapts its output frequency and
accelerates with the adjusted ramp to the given set value. During speed search CP.3
displays "SSF". The parameter determines, under what conditions the functions
operate. In case of several conditions the sum of the value must be entered.
Example: CP.26 = 12 means after reset and after auto-reset UP.

Quick stop time The fast-stop function is activated depending on CP.28. The parameter determines
the time needed to decelerate from 100 Hz to 0 Hz. The actual deceleration time is
proportional to the frequency change. The response to overtemperature (CP.28) is
disabled in the factory setting. If it is activated then the modulation switches off
automatically after 10 s if the motor is still too hot.

delta f
Adjustment range: 0,00...300,00 s
Resolution: 0,01 s
Factory setting: 2,00 s
Example: actual deceleration time = 5s; the drive should decelerate from 50 Hz to
0 Hz. delta f = 50 Hz - 0 Hz = 50 Hz
CP.27 = (100 Hz / 50 Hz) x 5 s = 10 s
