1.1 Product Description
In selecting the KEB COMBIVERT you have chosen a frequency inverter with the
highest demands for quality and dynamic.
It exclusively serves for a stepless speed regulation of the three-
phase motor.
The operation of other electrical loads is forbidden an can lead to
disturbances of the unit.
This manual describes the control of the standard series
COMBIVERT F4-Small
It includes: General installation and connection instructions
Explanation of the parameter structure
Operation of the keyboard surface
Description of all parameters
Parameter reference list to produce individual communication
program
KEB COMBIVERT is conditionally short-circuit proof (VDE 0160). After the internal
protector is reset the normal function is guaranteed.
Exceptions: If an earth-leakage fault or short-circuit proof often occur, this can
lead to a defect in the unit.
If a short-circuit occurs during regenerative operation (2nd or 4th
quadrant, feedback into the intermediate circuit), then this can lead
to a defect in the unit.
1.2 Safety Instructions
The KEB COMBIVERT is operated with voltage, which can cause an extremely
dangerous shock when come into contact with. Therefore the installation of the unit
and accessories is only permissible by qualified electro-personnel. A safe and trouble-
free operation is only possible when the valid regulations according to DIN VDE 0100,
IEC1000, EN 60204-1, EN 55014, EN 50082-2 and the relevant regulations for your
area are observed.
After clearing the frequency inverter the intermediate circuit capacitors are still charged
with high voltage for a short period of time. The unit can be worked on again after it
has been switched off for 5 minutes.
KEB COMBIVERT is adjusted so that after a voltage breakdown or an UP-error it can
restart alone. The machine manufacturer is responsible for the corresponding safety
precautions.

2.1 Connection Instructions
A trouble-free and safe operation of the frequecy inverter is only guaranteed when the
following connection instructions are observed. When deviated from malfunctions and
damages may occur in isolated cases.
•KEB COMBIVERT is only intended for a stationary connection
(discharge current > 3.5mA).
•Protective conductor cross section must be at least 10mm2copper or a 2nd
conductor must be electrically parallel to the protective conductor on separate
terminals (VDE 0160).
•Install electric power cable and control cable separately.
•Do not connect/disconnect the electric power cable and control cable when the
frequency inverter is energized.
•Observe mains voltage and motor rated voltage.
•Use shielded/drilled control lines. Shield on PE.
•Connection of the control cables is only possible on switch and adjustment
elements (relay, switch, potentiometer), which are suited for low voltages.
•Use shielded motor cables. Lay extensive shield on the motor housing.
•Connection of the braking module/braking resistor with shielded/drilled cables.
•Ground frequency inverter (asteroid; avoid earth circuits; shortest connection
to main earth).
All control wires should be included in further protective measures (e.g. doubly
insulated or shielded, grounded and insulated), since this deals with voltages in
accordance with VDE 0160, which are not securely separated from the mains circuit,
because basic insulation is used.
2.2 RCD (FI-Protective Switch)
If personnel protection is required during installation of the system the frequency
inverters must be protected according to EN 50178 (VDE 0160):
– 1-phase inverters by RCD type A (pulse-current sensitive FI’s) or type B (all-current
sensitive FI’s)
– 3-phase inverters (with B6 bridge-connected rectifier) by RCMA’s with separation
(used privileged) or RCD’s type B (all-current sensitive FI’s)
The tripping current should be 300mA or more, in order to avoid a premature triggering
of the inverter by discharge currents (about 200mA).
Dependent on the load, the length of the motor cable and the use of a radio
interference filter, substantially higher leakage current can occur.
The connection instructions from the manufacturer and the valid local reqirements
must be observed.
Dependent on the available mains form (TN, IT, TT) further protective measures are
necessary in accordance with VDE Part 410 (Part 4; Chapter 41). For example, with
TN-mains this protection is made with overcurrent protective devices. With IT-mains it
is insulation monitoring with a pulse-code measuring method. A protective separation
can be used with all mains forms as long as the required power and cable lengths
permit this.

2.3 Insulation Measuring
In order to prevent damages to KEB COMBIVERT the insulation measurements may
only be done in observance with important test conditions (see VDE 0558). The in- and
outputs of KEB COMBIVERT must be disconnected before insulation measurements
are done on the unit.
2.4 Connection of the Power Circuit
Dependent on the type of unit, not all power circuit terminals decsribed here are
available. A detailed description is found in the Instruction Manual for the Power
Circuit.
2.4.1 Mains Connection
1 - phase
(only 230V - class)
3 - phase
(230V and 400V class)
Exchanging the mains and motor connection causes immediate destruction of the unit.
2.4.2 Motor Connection
Note the supply voltage and
the correct polarization of
the motor!
With line lengths > 15m overvoltages can occur in the motor, which can endanger the
insulation system.

3 Parameter Structure
Each parameter is divided into 3 groups:
1. Parameter number
2. Parameter group
3. Parameter set (only with programmable parameters)
The parameter numbers distinguish between each parameter in a group. Parameter
groups are combined according to their functions. This means all parameters needed
to set a function are found in a parameter group. Combivert F4-S has the following
parameter groups.
Run(ru) - Parameter Contains all operating displays, i.e. all values
that change during operation, without changing
the parameter.
Operational(oP) - Parameter All parameters for the setpoint input, limitation,
ramp presetting etc.
Protection(Pn) - Parameter All protective functions (e.g. LA-Stop) and all
Keep-on-runnig functions (e.g. Auto Restart).
(uF) - Parameter Setting of volt/hertz-characteristic as well as the
modulation parameter (e.g. switching
frequency).
Drive(dr) - Parameter All motor specific parameters.
Control(cn) - Parameter Control parameters for speed and torque
User-definition(ud) - Parameter All parameters for individual setting of the
operating surface and the serial interface.
Free-prog.(Fr) - Parameter Programs and activates parameter sets.
Analog-I/O(An) - Parameter Programs the analog in-/outputs
Digital-In(di) - Parameter Programs the digital inputs.
Digital-Out(do) - Parameter Programs the digital outputs.
Level(LE) - Parameter Switching conditions for the digital outputs.
Information(In) - Parameter Information about inverter type, serial no. and
diagnostic parameter like error counter, Quality
Assurance number.

(op - Parameter)
There are 4 programmable parameters (parameter sets 0-3) and for each
programmable parameter up to 4 different values can be stored. The values of the
actual set selected are always active. Sets can be switched between during operation.
This switching is done via terminal strip, keyboard or bus interface.
Example: REF SOURCE (op.0) is programmed in all sets with 2
(frequency reference setting +/- Digital-Abs).
REF SETTING ABS (oP.1) has the following value in sets 0 - 3:
Set 0: 0 Hz
Set 1: 10 Hz
Set 2: 20 Hz
Set 3: 30 Hz
Depending on the set chosen the set value is 10, 20 or 30 Hz.
For all non-programmable parameters the same value is valid regardless of the set
selected.

4 Keyboard Operation
4.1 Standard Operation (Application Mode)
There are two fundamental operating modes for keyboard operation.
1. Displays and changes the parameter identification
(Number, group and set)
2. Displays and changes the parameter values.
To change between these modes press the FUNCT key. When the FUNCT key is
pressed in mode 1, the value of the parameter set is displayed. When pressed again
the parameter identification is displayed.
4.1.1 Display of Parameter Identification
The individual specifications for identification of the parameters are separated by dots.
One of these dots blinks and displays the specifications which can be changed by
UP/DOWN. The blinking dot can be shifted to the left by pressing ENTER. If ENTER is
pressed when the point is blinking, then the dot of the parameter number will blink
next. No set number is shown for non-programmable parameters. By pressing ENTER
you can only switch between parameter number and parameter group.
To select another parameter group press ENTER until the dot behind the parameter
group display blinks. The desired parameter group can now be set with UP/DOWN.
When the parameter group is changed, then the parameter number is set onto the
lowest parameter number available in the new group (generally 0).The adjusted set is
not changed. If the new parameter is not programmable then no parameter set is
visible.
To change the parameter number, the blinking dot must be brought behind the display
of the parameter number. Thereafter the parameter number can be changed with
UP/DOWN. If the largest parameter of a group is reached and UP is pressed, then the
lowest parameter number of this group appears. If the lowest parameter number is
reached and DOWN is pressed, then the largest parameter number of this group
appears. Changing the parameter number does not change the parameter group nor
the parameter set. No set number is displayed for non-programmable parameters.

Keyboard Operation

The parameter set can only be changed by a programmable parameter. After the
blinking dot is brought behind the display of the parameter set with ENTER, then the
desired set can be adjusted with UP/DOWN. This is not necessarily the set in which
the inverter presently operates, but rather the set of the parameter selected which
should be displayed or changed.
In addition to sets 0-3 the value A (active) can also be set. During this setting the value
is always shown which is being adjusted in the set presently active. The adjusted
parameter value cannot be changed in this setting.
4.1.2 Display of the Parameter Value
By pressing UP or DOWN the value of the adjusted parameter can be changed in the
parameter value display. These changes are effective immediately and permanently
stored, meaning they are still valid after the unit is switched off. ENTER does not need
to be pressed to confirm the input.
For some parameters it is not useful, that the value set by UP/DOWN immediately be
valid. When for example, during digital rotation setting you want to change from LS to
REV, then FOR may not immediately be activated when UP is pressed. These
parameters are called Enter parameters, because they must be verified by ENTER.
Only the display is changed when pressing UP /DOWN and not the value stored in the
inverter. When the display value and the stored value in the inverter are different, this
is characterized by a point in the display. The display value in the inverter is stored and
the dot is no longer visible when ENTER is pressed. The parameter value display of an
Enter parameter always begins with the value stored in the inverter. A list of all Enter
parameters is found in the supplement.
4.1.3 Special Displays
When a malfunction occurs in the inverter the display is overwritten by an error
message. This error message blinks. By pressing ENTER the display of the error
message is interrupted and the parameter value of the last parameter adjusted is
shown. No error reset occurs when ENTER is pressed, meaning the error status in the
inverter is not reset. As a result it is possible to correct adjustments before an error
reset. An error reset is only possible with the terminal control release or reset.
Some inputs, e.g. copying a set, are acknowledged with a message from the inverter.

4.2 The Customer Specified Parameter Group ( cP )
The cP parameter group is defined in the ud-group (USER DEFINTION) and can’t be
changed.
UP/DOWN is used to change between these parameters. A change of the group or set
is not possible. FUNCT is used to switch between the parameter value display and
parameter identification.
To change from the standard parameter group to the customer group and vice versa
the corresponding passwords must be entered (see chapter 5.7 / parameter ud. 0).

4.3 The Drive - Mode
The Drive-Mode is used to start the drive manually. In this mode it is only possible to
preset the direction of rotation and the digital frequency reference.
In addition to their normal function the keys have a special assignment:
ENTER key => Additional function F/R
(change of the direction of rotation)
FUNCT key => Additional function SPEED
(Presets the set frequency)
UP key => Additional function START
DOWN key => Additional function STOP
The set direction of rotation can be changed by F/R.
If the SPEED key is pressed, then the set frequency is shown. By simultaneously
pressing the UP or DOWN key the set frequency can be changed.

4.4 Password Structure
The password is entered with parameter ud. 0 (Application-Mode) and/or cP. 0
(Customer-Mode).
In this case the password remains stored after Power On and must not be released
again each time the unit is switched on. There are 5 password levels of which 1 is
always active. When a new password is entered the password level changes. Inputs
that do not match a valid password are ignored.
The supervisor password is not stored when the unit is switched off. Once the unit is
switched on again the password that was valid before the service password is active.
