3. Customer Parameters (CP-Mode)
3.1 General
Once the development stage of a machine is completed, usually only a few parameters are
required for the adjustment or the control of the inverter. To make the handling easier and
the user documentation more understandable as well as to increase the safety of operation
against unauthorized access, the possibility exists to create the one user surface with the
CP-Parameters. For that purpose 37 parameters (CP.00...CP.36) are available, 36 of them
(CP.01...CP.36) are free for assignment.
How the CP-Parameters are dened and normalized is described in the application manual.
3.2 Operating modes
Ex factory the COMBIVERT F5 is delivered in three different operating modes. The inputs
have different functions depending on the operation mode. Also the CP-Parameters prede-
ned by KEB are different.
Control with software Operating mode (Ud.02)
APPLICATION with encoder interface MULTI
APPLICATION without encoder interface GENERAL
ASCL (Asynchronous Sensorless Closed Loop) MULTI
SCL (Synchronous Sensorless Closed Loop) SERVO
The factory setting for the controls „BASIC“ and „COMPACT“ correspond to operating mode
„GENERAL“.

display "noP" and "LS", even if the control release or direction of rotation
are not switched (see CP.03). The rotation of the inverter is displayed by
the sign. Examples:
18.3 Output frequency 18,3 Hz, rotation forward
-18.3 Output frequency 18,3 Hz, rotation reverse
CP.02 Set frequency display
Co-domain Description
0…±400 Hz Display of actually set value. For control reasons the set speed is dis-
played, even if the control release or direction of rotation is not switched.
If no direction of rotation is set, the set frequency for clockwise rotation
(forward) is displayed.
CP.03 Inverter state
The status display shows the actual working conditions of the inverter. Possible displays and
their meanings are:
Display Status
nOP „no Operation“ control release not bridged; modulation switched off; output
voltage = 0 V; drive is not controlled.
LS „Low Speed“ no direction of rotation preset; modulation switched off; output
voltage = 0 V; drive is not controlled.
FAcc "Forward Acceleration" drive accelerates with direction of rotation forward.
FdEc „Forward Deceleration“ drive decelerates with forward direction.
rAcc "Reverse Acceleration" drive accelerates with direction of rotation reverse.
rdEc "Reverse Deceleration" drive decelerates with direction of rotation reverse.
Fcon "Forward Constant" drive runs with a constant speed and forward direction.
rcon "Reverse Constant" drive runs with constant speed and reverse direction.
Other status messages are described at the parameters, where they occur (see chapter 5
„Error diagnosis“).

the highest value of CP.04 is stored in CP.05. The peak value memory
can be cleared by pressing the UP, DOWN or ENTER key or via bus by
writing any value you like to the address of CP.05. The switch off of the
inverter also clears the memory.
CP.06 Utilization
Co-domain Description
0,0…200,00 % Display of the actual inverter rate of utilization in percent. 100% rate of
utilization is equal to the inverter rated current. Only positive values are
displayed, meaning there is no differentiation between motor and gener-
atoric operation.

t3 Deceleration time (CP.13)
CP.15 Boost
Co-domain Setting Description
0,0…25,5 % LTK In the lower speed range a large part of the motor voltage
decreases on the stator resistance. To keep the breakdown
torque nearly constant over the entire speed range, the voltage
decrease can be compensated by the Boost.
Adjustment:
• Determine the rate of utilization in no-load operation
• Preset about 10 Hz and adjust the boost, by way that the
same rate of utilization is reached as with rated speed.
When the motor, during continuous operation, drives with low speed and
too high voltage it can lead to an overheating of the motor.

3.3.4 Special Adjustments
The following parameters serve for the optimization of the drive and the adaption to certain
applications. These adjustments can be ignored at the initial start-up.

With this parameter a regulated output voltage in relation
to the rated frequency can be adjusted. Voltage uctua-
tions at the input and in the DC link have only low inu-
ence on the output voltage (V/f characteristic). The func-
tion allows an adaption of the output voltage to special
motors. The values must be conrmed with „ENTER“.
In the example below the output voltage is stabilized to
230 V (0 % boost).

CP.18 Switching frequency
Co-domain Setting Description
2 / 4 / 8 / 12 /
16 kHz
LTK The switching frequency with which the power modules are
clocked can be changed depending on the application. The
max.possible switching frequency as well as the factory setting
are specied by the power circuit. The values must be con-
rmed with „ENTER“.
Refer to following list to
learn about inuences and
effects of the switching fre-
quency.
low switching frequency high switching frequency
less inverter heating less noise development
less discharge current improved sine-wave simula-
tion
less switching losses less motor losses
less radio interferences improved controller charac-
teristics
improved concentricity with low
speed (only open loop!)
At switching frequencies above 4 kHz pay absolute attention to the max.
motor line length in the technical data of the power circuit manual.

CP.21 Fixed frequency 3 (input 2)
Co-domain Setting Description
CP.19
0…±400 Hz
5 Hz Three xed frequencies can be adjusted. The selection is
made by the inputs I1 and I2. If adjustments are made that
are outside the xed limits of CP.10 and CP.11, then the
frequency is internally limited. The negative values are re-
leased in application mode.
The rotation source of the xed frequencies is not changed
by CP.34, it always corresponds to CP.34 = 2.
CP.20 50 Hz
CP.21 70 Hz
