KEB COMBIVERT F4-F Lift Version 3.0 Kurzanleitung Seite 49

LF.36: Check the maximum torque in Nm of the motor and, if
With inspection speed check, whether the lift moves.
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
LF.51 Acceleration in m/s
LF.52 Deceleration jerk in m/s
LF.53 Deceleration in m/s
LF.54 Stopping jerk in m/s
The ramps becomes steeper by increasing the values, e.g. the jerk
values becomes 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.
Start-Up Instructions
If the error „E.EnC" or E.OS" occurs during the alignment or if
the alignment is not automatically completed, it must be
checked, if the motor cables UVW inverter correspond to UVW
motor. If the position of the encoder is known the value can be
entered directly as hexadecimal value in EC.07.
Let the motor rotate without ropes and with inspection speed
after the position alignment. If the error message „E.EnC" or
„E.OS" occurs during the alignment, check if the motor cables
UVW inverter are correspond to UVW motor, if necessary
change. The position alignment must be done again if the motor
cables are changed.
necessary, adjust it.
(Attention: If this parameter is adjusted too high for synchronous
machines and if the machine is permanently overloaded, it will
lead to demagnetization of the permanent magnets and the
destruction of the motor!)
