Tur.
5) At rated voltages ≥460 V multiply the rated current with factor 0.86
6) The voltage at the motor is dependent on the series-connected units and on the control method (example see chapter 3.3 in the annex)

The technical data are for 2/4-pole standard motors. With other pole numbers the inverter must be
dimensioned onto the motor rated current. Contact KEB for special or medium frequency motors.
The service life of the frequency inverter with intermediate voltage circuit depends on the current load
of the electrolytic capacitors in the intermediate circuit. The use of mains chokes can increase the
service life of the condensators to a considerable extent, especially when connecting to „hard“ power
systems or when under permanent drive load (continuous duty). For continuous duty (S1) drives with
a medium duty of >60%, KEB recommends the use of mains chokes with a terminal voltage (Uk) of
4%.
The term "hard" power system means that the nodal point power (SNet) of the mains is very high (>>
200) compared to the output rated power of the inverter (SA).

3.2 Connection of the Power Unit

All work from the transport, to installation and start-up as well as mainte-
nance may only be done by qualified personnel (IEC 364 and/or CENELEC
HD 384 and IEC-Report 664 and note national safety regulations). Accor-
Only Quali- ding to this manual qualified staff means those who are able to recognise
fied Electro- and judge the possible dangers based on their technical training and ex-
Personnel perience and those with knowledge of the relevant standards and who are
familiar with the field of power transmission.
KEB COMBIVERT units contain dangerous voltages which can cause death
or serious injury.
The KEB COMBIVERT can be adjusted in such a way that energy regene-
ration into the supply net is possible at regenerative operation also during
mains power failure. Therefore a dangerous high tension can exist in the
unit after switching off the supply system.
Electric Before working with the unit check the isolation from supply by mea-
Shock surements in the unit. Motors are to be secured against automatic
starting.
Care should be taken to ensure correct and safe operation to minimise risk
to personnel and equipment.

The terminal strips meet the requirements on IEC 60947-7-1

3.2.1 Connection of the voltage supply

++ The COMBIVERT G6-B corresponds to the inverter type
A1. This type can be supplied both by mains and via DC
L1 terminals. The starting current limiting is arranged before
L2 + the DC link. When using as DC output parallel connected
L3
frequency inverters must have their own starting current
limiting at the DC voltage input..

3.2.1.1 Wiring instructions

Never exchange the mains and motor cables.
Some countries demand that the PE-terminal is directly connected to the terminal box
(not over the mounting plate).

3.2.2 Connection of the motor

3.2.2.1 Selection of the motor cable
The correct cabling as well as the motor cable play an important part in case of low power
in connection with long motor line lengths. Ferrite cores and low-capacitance cable (phase/
phase<65 pF/m, phase/screen < 120 pF/m) at the output have the following effects:
• longer motor line lengths
• less abrasion of the motor gearbox by leakage currents
• better EMC properties

GB - 17
Connection of the Power Unit

3.2.2.2 Motor line length at operation with DC voltage

The maximum motor line length at DC operation is basically dependent on the capacity of the
motor cable. The internal filter is not active at DC operation. External measures must be taken
here, if necessary. The following data apply for operation under nominal rating conditions.

3.2.5.2 Note to the function
In the example above the locking of the line contactor K1 is interrupted in case of overheating
of the braking resistor. The line contactor drops and switches off the mains voltage. The au-
xiliary contacts 13/14 open the error linkage circuit at terminals I1/COM and release an error.
The modulation is switched off. Thus the drive in generatoric operation does not regenerate
further energy into the DC link circuit.

GB - 21
Connection of the Power Unit

Depending on the case of application (e.g. no generatoric operation) simple circuits

can be used. See chapter 7 for instructions of the download. Input I1 must be program-
med and inverted in the application mode to "external error".

Permissible:
If a voltage test shall be done the inverter may be disconnected for this, since a voltage test
with 2180 Vdc according to EN 61800-5-1 is done ex factory.

CP.17 Voltage stabilization
With this parameter a regulated output voltage in relation to the rated frequency can be adjus-
ted. For that reason voltage variations at the input as well as in the intermediate circuit only
have a small influence to the output voltage (U/f-characteristic). The function allows, among
other things, an adaption of the output voltage to special motors.
CP.22 DC braking / Mode
With DC-braking the motor is not decelerated by the ramp. Quick braking is caused by D.C.
voltage, which is applied onto the motor winding. This parameter determines how the DC
braking is triggered.
Value Activation
0 DC-braking deactivated
1 DC-braking at switch off of the direction of rotation and upon reaching 0 Hz. The
braking time is CP.23 or until the next direction of rotation.
2* DC-braking as soon as setting for the direction of rotation is absent.
3* DC-braking as soon as the direction of rotation changes or is absent.
4* DC-braking at switch off of the direction of rotation and upon reaching 4 Hz.
5* DC-braking when the real frequency falls below 4 Hz and the drives decelerates
6* DC-braking as soon as the set value falls below 4 Hz.
7 reserved
8 reserved
9 DC-braking after switching on the modulation.
* Braking time depends on the actual frequency.
CP.24 Max. ramp current
This function protects the frequency inverter against switching off through overcurrent during
the acceleration ramp. When the ramp reaches the adjusted value,it is stopped so long until
the current decreases again. CP.03 displays "LAS" at active function.

GB - 32
 Parameter Description

CP.25 Max. constant current

This function protects the frequency inverter against switch off through overcurrent during
constant output frequency. When exceeding the adjusted value, the output frequency is redu-
ced until the value drops below the adjusted value. CP. 03 displays "SSL" at active function.
CP.26 Speed search condition
When connecting the frequency inverter onto a decelerating motor, an error can be triggered
by the differing rotating field frequencies. With activated speed search the inverter searches
for the actual motor speed, adapts its output frequency and accelerates with the adjusted
ramp to the given set value. During speed search CP.03 displays "SSF". The parameter de-
termines, under what conditions the functions operate.
In case of several conditions the sum of the value must be entered. Example: CP.26 = 12
means after reset and after auto-reset UP.
Value Condition
0 Function off
1 at control release
2 at switch on
4 after reset
8 after Auto-Reset UP
CP.27 Motor protection / response
The motor protective function protects the connected motor against thermal destruction
caused by high currents. The function corresponds largely to mechanical motor protective
components, additionally the influence of the motor speed on the cooling of the motor is taken
into consideration. The load of the motor is calculated from the measured apparent current
(CP.04) and the adjusted rated motor current (CP.29).
For motors with separately driven fan or rated frequency of a self-ventilated motor following
tripping times (VDE 0660, part 104) apply:
1,2 • Rated current ≤ 2 hours
1,5 • Rated current ≤ 2 minutes
2 • Rated current ≤ 1 minute
8 • Rated current ≤ 5 seconds

In case of failure CP.27 activates the motor protection function and adjusts the corresponding
response as follows:
CP.27 Response Description
0 Error, Immediate switch off of modulation. Correct the error for
restart after reset the restart and activate reset.
Error message E.xx The prewarning changes into an error. The drive remains
in the error state until a reset signal is recognized.

CP.28 Motor protection / mode
The cooling mode of the motor is adjusted with these programmable parameters.
Value Condition
0 Motor with separate cooling
1 Motor with self-cooling
For self-ventilated motors the tripping times decrease with the frequency of the motor. The
motor protective function acts integrating, i.e. times with overload on the motor are added,
times with underload are substracted. After triggering the motor protective function, the new
tripping time is reduced to 1/4 of the specified value, if the motor has not been operated for
an appropriate time with underload.
CP.29 Motor protection / rated current
This parameter specifies the rated current (= 100% utilization) for the motor protective func-
tion. The motor protection-load is calculated as follows:

Inverter apparent current (CP.04)

Motor protection load = –––––––––––––––––––––––––––––––

CP.35 AN1 Set value selection
The setpoint input (AN1) of the control can be triggered with different signal levels. In order to
correctly evaluate the signal, this parameter must be adapted to the signal source.
Value Set value signal
0 0…10 V DC / Ri = 29 kΩ
1 0…±20 mA DC / Ri = 500 Ω
2 4…20 mA DC / Ri = 500 Ω

CP.36 Select 50/60Hz mode

When units or machines are delivered in the area of application of UL an adaption of the fac-
tory setting to the valid operating data there can be done with this parameter.
Value Default value
0 Current values and limits, motor data, frequencies and speed relate to a 50 Hz
mains with 400 V rated voltage.
1 Current values and limits, motor data, frequencies and speed relate to a 60 Hz
mains with 460 V rated voltage.

CP.37 Response of external overtemperature (only for devices with temperature input)
This parameter determines the response of the drive to the external temperature monitoring.
The function is switched off at factory setting. The power circuit terminals T1/T2 must be
connected to activate the function. Then the response can be adjusted according to the fol-
lowing table. If overheat no longer exists, the message E.ndOH (or A.ndOH) is output. Only
then the error can be reset or the automatic restart can be carried out.
CP.37 Display Response Restart
0 E.dOH Immediate disabling of modulation
1* A.dOH Quick stopping / disabling of modulation after re- Remove fault;
aching speed 0 reset
2* A.dOH Quick stopping / holding torque at speed 0
3 A.dOH Immediate disabling of modulation
4* A.dOH Quick stopping / disabling of modulation after re- Autoreset, if no
aching speed 0 fault is present
5* A.dOH Quick stopping / holding torque at speed 0
6* none No effect on the drive; switching condition "PTC
overtemperature warning" (value 9) is set and can
be used with CP.31/32 to activate an output. inapplicable
7 none No effect on the drive; Malfunction is not pre-
sent ! Switching condition „External overtempera-
ture“ (value 9) is not set.
*) If the motor is still too hot after 10 seconds, the error E.dOH is triggered and the modulation
is switched off!

A.1 Calculation of the motor voltage
The motor voltage for dimensioning of the drive is depending on the used components. The
mains voltage reduces according to the following table:
Mains choke Uk 4% Example:
Inverter open loop 4 % Closed loop inverter with mains- and motor choke at
Inverter closed loop 8 % non-rigid supply system:
Motor choke Uk 1% 400 V mains voltage - 15 % = 340 V motor voltage
Non-rigid supply 2 %
system
A.2 Maintenance
All work may only be done by qualified personnel. The security must be ensured as follows:
• Disconnect power supply at MCCB
• Secure against restarting
• Await discharge time of capacitors
(if necessary controlling by measurement at “++“ and „--“)
• Ensure loss of voltage by measurement

In order to avoid premature ageing and avoidable malfunctions, the measures mentioned
below must be carried out in the appropriate cycle.
Cycle Function
Pay attention to unusual noises of the motor (e.g. vibrations) as well as of the
frequency inverter (e.g. fan).
Constant
Pay attention to unusual smells of the motor or frequency inverter (e.g. evapo-
ration of capacitor electrolyte, braise of the motor winding)
Check unit for loose screws and plugs and if necessary tighten up.
Clean frequency inverter from dirt and dust deposits. Pay attention especially
to cooling fins and protective grid of the fans.
Examine and clean extracted air filter and cooling air filter of the control cabi-
Monthly
net.
Examine function of the fans of the KEB COMBIVERT. The fan must be repla-
ced in case of audible vibrations or squeak.
Make a visual leak test of the cooling circuit for water-cooled inverters.
A.3 Shut down
A.3.1 Storage
The DC link of the KEB COMBIVERT is equipped with electrolytic capacitors. If electrolytic
capacitors are stored de-energized, the oxide film working as dielectric fluid reacts with the
acidic electrolyte and destroy themselves slowly. This affects the dielectric strength and the
capacity.
If the capacitor starts running with rated voltage, it is tried to build the oxide film abrupt again.
This causes heat and gas and leads to the destruction of the capacitor.
In order to avoid defectives, the KEB COMBIVERT must be started up depending on the sto-
rage period in accordance with the following specification:

GB - 38
 Annex

Storage period < 1 year

• Start-up without special measures
Storage period 1…2 years
• Operate frequency inverter one hour without modulation
Storage period 2…3 years
• Remove all cables from the power circuit; especially of braking resistor or module
• Open control release
• Connect variable transformer to inverter input
• Increase variable transformer slowly to indicated input voltage (>1 min) and remain at
least on the specified time.
Voltage class Input voltage Residence time
0…280 V 15 min
400 V 280…400 V 15 min
400…500 V 1h
Storage period > 3 years
• Input voltages as before, however double the times per year. Eventually change capaci-
tors.

After expiration of this start-up the KEB COMBIVERT can be operated on nominal rating con-
ditions or delivered to a new storage.

B.1 Certification
B.1.1 CE Marking
CE marked frequency inverters and servo drives were developed and manufactured to com-
ply with the regulations of the Low-Voltage Directive 2006/95/EC.
The inverter or servo drive must not be started until it is determined that the installation com-
plies with the Machine directive (2006/42/EG) as well as the EMC-directive (2004/108/EC)
(note EN 60204).
The frequency inverters and servo drives meet the requirements of the Low-Voltage Direc-
tive 2006/95/EC. The harmonized standards of the series EN 61800-5-1 in connection with
EN 60439-1 and EN 60146 were used.
This is a product of limited availability in accordance with IEC 61800-3. This product may
cause radio interference in residential areas. In this case the operator may need to take cor-
responding measures.
