KEB COMBIVERT F4-F Lift Version 3.0 Kurzanleitung Seite 45

Start-Up Instructions
Optimization
In case of error message „E.OL2" adjust LF.38=0 (8 kHz operating
frequency).
In case of wrong travel direction (up and down exchanged) activate
the reversal of driving direction with LF.05=1.
The driving comfort can be optimized with the following parameters:
LF.50 Starting jerk in m/s 3
LF.51 Acceleration in m/s 3
LF.52 Deceleration jerk in m/s 3
LF.53 Deceleration in m/s 3
LF.54 Stopping jerk in m/s 3
The ramps become steeper by increasing the values, e.g. the jerk
value becames harder.
If the cabine rolls back when releasing the brake, increase LF.33 in
steps of 500.
If the lift at the beginning of the drive runs against the brake, increase
LF.70 (brake release time) because the brake release is not fast
enough.
The brake engage time can be increased with parameter LF.79, if the
brake is not closed after stopping when the inverter switches off the
modulation.
