Tilting protection
Avoids an uncontrolled tilting of the speed.
Functionality:
The motor current is recorded by a
fi
lter (parameter "s_FIL").
If the setted limit value for the current (Parameter "I_KIPP") is exceeded, the setpoint for the speed
will be reduced linear to the motor current.

Improvements with Open-Loop-operation
Information
The described possibilities for improvements apply only to parameter which are available only in the
U/f-operation mode (Open-Loop).
Possibilities for improving travel curve or the signal-timing are described in the chapter
"Commissioning".
15.8.4.1
Optimizing start up behavior
If the motor turns back when starting up, does not start or an overcurrent occurs immediately after
opening the mechanical brake, the minimum current that is fed to the motor is too low. In this case, the
Control / I_IxR
parameter can be increased to minimise travel.

15.8.4.2
Slip-compensation
Due to the different speeds in upwards and downwards direction the different positioning travels or
inexactness during the stopping can occur. By having nearly the same speed in both directions these
inaccuracies can be minimised. The adjustment of the speed is carried out by the slip-compensation.
The slip-compensation will be activated with the parameter
Controller/s_COMP=On
.
