CP-Parameter for open-loop operation
4* DC-braking at switch off of the direction of rotation and upon reaching 4 Hz.
5* DC-braking when the real frequency falls below 4 Hz and the drives decelerates
6* DC-braking as soon as the set value falls below 4 Hz.
7* DC braking if prog. input I4 is set
8 DC braking as long as prog. input I4 is set
9 DC-braking after switching on the modulation.
10 The input occurs by the sum of the desired conditions + “10”.

* Braking time depends on the actual frequency.
CP23 DC braking time
Co-domain Setting Description
0.00…100.00 s 10 s If the braking time is depending on the actual frequency
(CP22 = 2...7) it is calculated as follows:

CP24 LAD load level
This function protects the frequency inverter against switching off through overcurrent during
the acceleration ramp. When the ramp reaches the adjusted value, it is stopped so long until
the current decreases again. "LA stop" is displayed (CP03) when the function is active.
