KEB COMBIVERT F4-F, Quick Reference

GB-14

dr.00: Enter rated motor power in kW
dr.01: Enter rated motor speed in rpm
dr.02: Enter rated motor current in A
dr.03: Enter rated motor frequency in Hz
dr.09: Enter rated motor torque in Nm
dr.17: Enter EMK voltage constant in V/1000 rpm (if only the rated

motor voltage is known, EMK can be calculated according to
following formula: U

EMK

 = U

N

 / n

N

 x 1000 rpm)

dr.41: Enter winding resistance in Ohm
dr.42: Enter winding inductivity in mH

EC.01: Enter encoder pulse number

EC.04: Enter value „1“ to execute a position alignment and give a

drive command. Cancel drive command, when value „5“ is
displayed.  In doing so make sure that the machine is unloaded,
i.e. the ropes may not rest upon the traction sheave.
If the position alignment is successful completed, value „7“ is
displayed.
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 ente-
red 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.

LF.36: Check the maximum torque in Nm of the motor and, if

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!)

With inspection speed check, whether the lift moves.
