Start-Up Instructions
3.1 Commissioning of
an Asynchronous
MachinewithGearbox
3. Start-Up
Instructions
The following procedure is recommended for the commissioning of
theKEBCOMBIVERTF4-Flift version3.0withasynchronous machine
and gearbox:
Adjust the parameters in ascending sequence, as this initiates partial
presettings of the unit. Start with the lift data (LF-parameter). Save
the adjusted data by activating the „Enter key“.
LF.00: Enter password (440)
LF.02: Enter setpoint setting/rotation setting
1 = Binary coded setpoint setting
2 = Input coded setpoint setting
3 = Analog setpoint setting 0...+10V
4 = Analog setpoint setting -10...+10V
LF.04: Check, if the value „0“ is adjusted (asynchronous machine)
LF.20: Enter system speed in m/s
LF.21: Enter the diameter of the traction sheave in mm, if necessary,
remeasure
LF.22: Enter gear reduction, if necessary, count
LF.23: Enter rope suspension (1 for 1:1, 2 for 2:1 etc.)
LF.24: Enter nominal load (lifting capacity) of the cabine in kg
LF.30: Select control procedure (0 = without feedback, 2 = with
feedback)
LF.40: Enter correction speed in m/s
LF.41: Enter crawl speed in m/s
LF.42: Enter rated speed in m/s
LF.43: Enter inspection speed in m/s
dr.00: Enter rated motor power in kW (1 kW = 1.36 PS)
dr.01: Enter rated motor speed in rpm (not synchronous speed)
dr.02: Enter rated motor current in A
dr.03: Enter rated motor frequency in Hz
dr.04: Enter cos phi of the motor
dr.12: Enter rated motor voltage in V (if the value to be adjusted is
already entered, it is essential to acknowledge the value with
ENTER)
EC.01: Enter encoder pulse number
With inspection speed check, whether the lift moves. In case of error
message „E.EnC“ execute an encoder track change with EC.2=1.
Reset the error message through switch off and switch on.

GB-12
Start-Up Instructions
LF.30=0must beadjusted,if themotorshall bedrivenwithoutencoder.
If the load cannot be lifted with this, increase LF.37 (torque increase).
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/s3
LF.51 Acceleration in m/s3
LF.52 Deceleration jerk in m/s3
LF.53 Deceleration in m/s3
LF.54 Stopping jerk in m/s3
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.
If the lift does not reach the rated speed during ‘empty-downward-
drive’ (display LF.90), do the following:
- Set cos phi (dr.04) to 0.9
- Decrease field weakening speed (dr.19) to approx. 2/3 of the
synchronous speed (approx. 1000 rpm with 4-pole motors; approx.
680 rpm with 6-pole motors)
- decrease rated motor speed (dr.01) in steps of 20 until the rated
speed is reached during a downward drive.

3.2 Commissioning of a
Gearless Permanent
Magnet Machine
Start-Up Instructions
The following procedure is recommended for the commissioning of a
KEB COMBIVERT F4-F lift version 3.0 with a gearless permanent
magnet machine:
Adjust the parameters in ascending sequence, as this initiates partial
presettings of the unit. Start with the selection of the motor and the
resolution and adjustment of the lift data (LF-parameter). Save the
adjusted data by activating the „ENTER key“.
When using a synchronous machine with Hiperface-encoder (inverter
part no. xx.F4.Fxx-xi5x), the motor, encoder and control data are
automatically transferred from the encoder to the inverter at the first
switch on.However, the encoder must be preset with the data.Please
inquire at your motor manufacturer, whether this has been done. If
the data is stored in the encoder, the entire „dr“ and „EC“-parameters
aswellas LF.30- LF.36 neednot tobeentered intheinverter anymore.
LF.00: Enter password (440)
LF.02: Enter setpoint setting/rotation setting
1 = Binary coded setpoint setting
2 = Input coded setpoint setting
3 = Analog setpoint setting 0...+10V
4 = Analog setpoint setting -10...+10V
LF.04: Adjust value “1”
LF.06: Adjust value “1”
LF.20: Enter system speed in m/s
LF.21: Enter the diameter of the traction sheave in mm, if necessary,
remeasure
LF.22: Enter gear reduction 1
LF.23: Enter rope suspension (1 for 1:1, 2 for 2:1 etc.)
LF.24: Enter nominal load (lifting capacity) of the cabine in kg
LF.31 to LF.33: Enter speed controller data (Use pracmatical values
or inquire about adjustment at KEB.)
LF.40: Enter correction speed in m/s
LF.41: Enter crawl speed in m/s
LF.42: Enter rated speed in m/s
LF.43: Enter inspection speed in m/s

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: UEMK = UN/ nNx 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. Indoingso makesure thatthemachineisunloaded,
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 themotor cables UVWinverter correspondtoUVW
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.Theposition alignmentmustbedoneagain ifthemotor
cables are changed.
LF.36: Check the maximum torque in Nm of the motor and, if
necessary, adjust it.
(Attention:Ifthisparameterisadjusted toohigh forsynchronous
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.

- Set cos phi (dr.04) to 0.9
- Decrease field weakening speed (dr.19) to approx. 2/3 of the
synchronous speed (approx. 1000 rpm with 4-pole motors; approx.
680 rpm with 6-pole motors)
- decrease rated motor speed (dr.01) in steps of 20 until the rated
speed is reached during a downward drive.

3.4 Commissioning of a
Permanent Magnet
MachinewithGearbox
The following procedure is recommended for the commissioning of
the KEB COMBIVERT F4-F lift version 3.0 with permanent magnet
machine and gearbox:
Adjust the parameters in ascending sequence, as this initiates partial
presettings of the unit. Start with the selection of the motor and the
resolution and adjustment of the lift data (LF-parameter). Save the
adjusted data by activating the „Enter key“.
LF.00: Enter password (440)
LF.02: Enter setpoint setting/rotation setting
1 = Binary coded setpoint setting
2 = Input coded setpoint setting
3 = Analog setpoint setting 0...+10V
4 = Analog setpoint setting -10...+10V
LF.04: Adjust value „1“
LF.20: Enter system speed in m/s
LF.21: Enterdiameter ofthe tractionsheave,if necessary,remeasure
LF.22: Enter gear reduction, if necessary, count
LF.23: Enter rope suspension (1 for 1:1, 2 for 2:1 etc.)
LF.24: Enter additional load (lifting capacity, payload) of the cabine in kg
LF.31 to LF.33: Enter speed controller data (use pracmatical values
or inquire about adjustment at KEB)
LF.40: Enter correction speed in m/s
LF.41: Enter crawl speed in m/s
LF.42: Enter rated speed in m/s
LF.43: Enter inspection speed in m/s
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 motor
voltageisknown, EMKcan becalculatedaccordingto following
formula: UEMK = UN/ nNx 1000 rpm)
dr.41: Enter winding resistance in Ohm
dr.42: Enter winding inductivity in mH
EC.01: Enter encoder pulse number. (If a resolver is used, the
parameter must not be changed).
EC.04: Enter value „1“ to execute a position alignment and give a
drive command. Cancel drive command, when value „5“ is
displayed. Indoingsomake surethatthemachineis unloaded,
i.e. the ropes may not rest upon the traction sheave.
If the position alignment is successful completed, value „7“ is
displayed.

Optimization
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 themotor cables UVWinverter correspondtoUVW
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 positionalignmentmustbe doneagainifthe motor
cables are changed.
LF.36: Check the maximum torque in Nm of the motor and, if
necessary, adjust it.
(Attention:Ifthisparameterisadjusted toohigh forsynchronous
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.
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/s3
LF.51 Acceleration in m/s3
LF.52 Deceleration jerk in m/s3
LF.53 Deceleration in m/s3
LF.54 Stopping jerk in m/s3
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.
