(in conformity with the low-voltage directive 73/23/EEC)
1. General
AC motor controls, depending on their degree of protection,
may have exposed live, un-insulated, and possibly also moving or rotating parts, as well as hot surfaces.
Removal of the protective covers, improper use, improper installation or operation, can be dangerous and result in serious
personal injury and or damage to property.
This document must be read in its entirety before attempting to
apply voltage to the KEB COMBIVERT F5.
All functions of, installation and commissioning as well as
maintenance are to be carried out by skilled or certified technical personnel (Observe IEC 364 or CENELEC HD 384 or DIN
VDE 0100 and IEC 664 or DIN/VDE 0110, NEC and all national and local codes and accident prevention rules!).
For the purposes of these basic safety instructions, ”skilled technical personnel“ means persons who are familiar with the installation, mounting, commissioning and operation of the product and have the qualifications needed for the performance of
their functions.
2. Intended use
AC motor controls are components designed for installation and
operation in electrical installations or machinery.
In case of installation in machinery, commissioning of the drive
converter (i.e. the starting of normal operation) is prohibited
until the machinery has been proved to conform to the provisions of the directive 89/392/EEC (Machinery Safety Directive
- MSD). Account is to be taken of EN 60204.
Commissioning (i.e. the starting of normal operation) is admis-
sible only where conformity with the EMC directive (89/336/
EEC) has been established. The KEB COMBIVERT F5 motor
controls meet the requirements of the low-voltage directive 73/
23/EEC. They are subject to the harmonized standards of the
series DIN EN 50178/VDE 0160 in conjunction with EN 604391/ VDE 0660, part 500, and EN 60146/ VDE 0558.
The technical data as well as information concerning the supply conditions shall be taken from the name plate and from the
documentation and shall be strictly observed.
3. Transport, storage
The instructions for transport, storage and proper use shall be
complied with.
The climatic conditions shall be in conformity with EN 50178.
4. Installation
The installation and cooling of the unit shall be in accordance
with the specifications contained with in this document.
The unit shall be protected against excessive force or strain. In
particular, no components must be bent or isolating distances
altered in the course of transportation or handling. No contact
shall be made with electronic components and contacts.
Drive converters contain electrostatic sensitive components
which are can be damaged through improper use or handling.
Electric components must not be mechanically damaged or
destroyed (potential health risks).
5. Electrical connection
RISK OF ELECTRIC SHOCK! Always disconnect the supply
voltage before installing or servicing the KEB COMBIVERT F5
motor control! Wait five minutes for the before attempting to
change any connections as the internal DC bus must first discharge.
If it is necessary to work with the voltage supply turned on,
always comply with the applicable national accident prevention
rules (ex O.S.H.A.).
The electrical installation shall be carried out in accordance
with the relevant requirements (NEC and local codes). For further information, see documentation.
Instructions for installation in accordance with EMC requirements, like shielding, grounding, location of filters and wiring,
are included in the documentation. They must always be complied with. Motor controls bearing a CE marking do not preclude adherence to proper EMC installation requirements. Observance of the allowed values required by EMC law is the
responsibility of the designer or manufacturer of the installation or machine.
6. Operation
Installations which include motor controls shall be equipped
with additional control and protective devices in accordance
with the relevant applicable safety requirements. Changes to
the motor control by means of the operating software are admissible.
After disconnection of the motor control from the supply voltage, live parts and power terminals must not be touched because DC BUS capacitors may still be energized. Always follow the printed warnings on the unit.
During operation, all covers and doors shall be kept closed.
7. Maintenance and servicing
The manufacturer’s documentation shall be followed.

• Most units have forced airflow from bottom to top using a thermostatically controlled
variable speed fan. Leave space above and below the unit for proper air flow.
• Prevent dust or debris from entering the unit, especially during the construction of the
control panel. Metal chips can cause internal shorts or malfunctions.
• Installation in a sealed enclosure requires proper cooling, be sure to over size control
cabinet or provide suitable cooling device.
• Protect the unit against conductive and corrosive gases and liquids.
• Water, mist, or steam should not be allowed into the unit.
• Do not allow water to condense within the unit
• The COMBIVERT F5 must not be installed in a “Explosion Proof” environment.

Installation and Connection
3.2 Good EMC Installation Techniques
1) Mount the COMBIVERT F5 on a conductive
(zinc or nickel plated not painted) subpanel.
This sub plate serves as the central grounding
point for the machine.
2) Always connect the shield of motor and
control cables with maximum surface area,
use a metal cable clamp to contact cable
shield on all sides. Using a single strand of
the shield or the drain wire from the shield
as the only connection can reduce the
shield’s effectiveness by 70%.
3) The distance between control and power
cables should be at least 10..20 cm / 4...8
inches.
4) Keep the motor and power cable spatially
6
separated especially if running parallel.
5) If it cannot be avoided, cross control and
power cables and motor cables at a right
angle.
6) Install all cables as close as possible to the
mounting plate - ideally in a metal wireway.
7) Ridged metal conduit can be used as a
shield for the motor cables. Always observe
the following points:
• Remove all paint from the control panel where the conduit is to be secured.
• Securely fasten all conduit fittings.
• Run only the motor wires through the conduit. All other wires must be pulled
through a separate conduit.
• Connect the control panel to the sub panel with a heavy ground strap.
8) If a KEB EMI (CE) filter is used, it must be mounted as close as possible and to the
same subpanel as the COMBIVERT F5 motor control. The filter must have large bare
surface contact with the subpanel. Use only the wires from the filter to connect to the
inverter. Never add additional lengths of wire.
9) All ground connections should be as short as possible. Always avoid creating ground
loops. NEC requires a ground conductor connected to every COMBIVERT F5 controller
in spite of the metal on metal connection to the subpanel.
You can find further instructions regarding EMC and proper wiring considerations by
contacting KEB technical support or visiting the web site www.kebamerica.com.

3.3 Connection of Power Circuit
3.3.1 Wiring instructions
RISK OF ELECTRIC SHOCK! Always disconnect supply voltage before servicing the
COMBIVERT F5. Wait 5 minutes before attempting to change the connections as the
DC Bus capacitors may still be charged.
Absolutely pay attention to the nameplate voltage of the KEB COMBIVERT and the
connected line voltage. A 230V-unit will be immediately destroyed on a 460V-power
supply. Never exchange the line and motor cables. The unit will be destroyed.
The COMBIVERT F5 motor controls specified in this manual are suitable for use on a circuit
capable of delivering not more than 10kA rms symmetrical ampers at the rated maximum
voltage.
Connection of the F5 series motor control to voltage systems configured as corner grounded
delta, center tap grounded delta, open delta, or ungrounded delta may defeat the internal
noise suppression. With this type of voltage supply the maximum phase to ground voltage is
300VAC for 230 VACrms units and 500 VACrms for 600VAC units. A balanced, center ground
wye connection is always recommended. The three phase voltage imbalance must be less
than 2% phase to phase. Greater imbalance can lead to destruction of the unit.

3.3.4 Motor Overload Protection
The COMBIVERT F5 motor control by default provides motor overload protection at 130% of
the unit’s rated output current. See tables in section 2.3 for rated output current. Two additional
motor overload protection systems are available.
Electronic Motor Overload Protection
This software function provides speed dependent I2t overload protection and is approved
by UL as a solid state overload protection device according to UL508C section 42 and NEC
430 Part C. The trip current is adjustable as well as whether the motor is self cooled or
blower cooled.
Motor Winding Temperature Sensor
• Connects to Terminals T1, T2. These terminals as default need to be jumpered.
• Trip resistance level 1.65...4 kOhm
• Reset resistance level 0.75...1.65 kOhm
• This function can be activated or deactivated through a software parameter. The default
setting is On.
• Do not run sensor wires in the same conduit or wire way as other control cables. These
sensor wires most likely are carrying high frequency noise from the motor.
• If the sensor wires are part of the motor cable they must be shielded independently from
the motor wires.
3.3.5 Motor Terminal Connections
The motor connections should always be verified for correct voltage configuration before
power is appiled. (jumpers may be in place from factory testing) The motor terminals (U,V,W)
from the indexing drive, should be connected to the motor terminals U1, V1, W1.

The ground terminal at the motor should be connected to the ground terminal on the inverter.
The motor cables should be shielded and the sheild should be connected to the inverter. The
direction of rotation of the motor can be changed by reversing any two phases. (U1 to V1,
V1 to U1)
Terminals T1&T2 need to be jumpered on the inverter if not
using a thermo sensing device. The 230VAC A-Housing
doesn’t have these terminals.

3.3.7 EMI(CE) Filters
The KEB COMBIVERT frequency inverters are optionally available with EMI filters. If
you have a 1/2, 1, 2 Hp 460VAC system your unit comes equipped with this item. These
filters allow the KEB COMBIVERT to meet CE EMC directive 89/339. All filters are
dimensioned for the inverter’s rated current and are designed to meet the conducted
emission limit as defined by EN55011/B.
The filter kits contain all required hardware for installation. The filters include the
sheilded supply wires which connect the filter to the inverter. Depending on the
available space and filter type, the filter can either be installed under the frequency
inverter (Back Mount), or beside the frequency inverter (Panel Mount).

3.4 Breaking Resistor
3.4.1 Explanation
The COMBIVERT F5 inverter can be equipped with an external braking resistor for
limited 4 quadrant operation. The energy the motor regens into the inverter during deceleration is dissipated through the internal braking transistor to the braking resistor.
The braking resistor heats up during braking. If it is installed inside a control
cabinet, sufficient interior cooling must be provided! The resistor should be
mounted above and a minimum of 9 inches away from the inverter or in a separate
enclosure!
Peak power is classified as the peak repetitive power dissipation with a 6 sec
on time and 120 sec cycle time. KEB can offer many types of braking
resistors, please contact your sale representative for more information.
Peak power is classified as the peak repetitive power dissipation with a 3 sec
on time and 120 sec cycle time. The Back Mount Breaking Resistor adds 1.2
inches onto the height of the inverter.

Installation and Connection
3.4.3 Connection
Braking resistor connection with high temperature drive fault
• The resistor has a PTC type sensor and is connected to the
T1, T2 terminal on the COMBIVERT F5. If a motor
temperature sensor and braking resistor sensor is used they
should be placed in series. Note: if the braking transistor in
the unit fails, there is no guarantee the voltage to the resistor
will be shut off!
Braking resistors can develop very high surface
temperatures, therefore install away from other
devices, above the motor control and where people
can not inadvertently come in contact with it.
* The panel mount breaking resistors listed on page 22 have a NC thermal contact rated
at 180°C/356°F. Back mount resistors have a thermal contact rated at 90°C/194°F.
Braking resistor connection with high temp disconnect feature
• The resistor has a NC
mechanical switch type
temperature sensor.
• If the resistor becomes too
hot, the sensor switch
opens and disconnects the
COMBIVERT F5 from the
supply voltage.
• In the event of a complete
failure of the internal
braking transistor, this is
the only way to disconnect
the resistor from the power
source!

3.4.4 Selection
Different braking resistors are available from KEB. They are selected according to their
application requirements. The selection formulas and technical data of the resistors are
listed on the following pages. In most cases the suggested braking resistor is sufficant.
This can be verified using the procedure below.
*Braking resistors aren’t required on 1/3 to 1 HP applications
1.Establish desired braking time.
2.Calculate braking time without braking resistor (t
3.If the desired braking time is shorter than the calculated braking time, it will be necessary to use a braking resistor. (tB < t
4. Calculate braking torque (TB) taking the load torque (TL) into
Bmin
)
account. TL is a positive value for friction and windage and negative for overhauling loads.
5.Calculate peak braking power (PB). This must always be calculated for the "worst
case" (n
6.Selection of the braking resistors:
to standstill).
max
a)The resistor should be selected so that PR > P
b)PN is to be selected according to the duty cycle factor (d.c.f.).
The braking resistors may only be used for the specified value. The maximum
ON period of the braking resistor may not be exceeded.
6 % d.c.f. =maximum braking time 8 s
25 % d.c.f. =maximum braking time 30 s
40 % d.c.f. =maximum braking time 48 s
Longer ON periods require specially-designed braking resistors. Take into ac
count the current through the braking transistor.
7.Check whether the desired braking time is attained with the selected braking resistor
(t
).
Bmin
Note: Consider the capacity of the braking resistor and motor. The braking torque may
not exceed the rated torque of the motor by more than 1.5 times. To realize maximum
possible braking torque, the frequency inverter must be sized for the increased motor
current.
Braking time
The braking time is adjusted in the frequency inverter through the deceleration parameters. If the selected deceleration time is too short, either the peak inverter current level
or the maximum DC bus voltage will be exceeded. The error message
result. The following formulas can be used to determine an allowable braking time.

• Use shielded cable with twisted pair wires.
• Terminate shield wires to earth ground, only at inverter.

• Separate control and power wires 8" or more apart.
• Control and power wires to cross at a right angle.

As a momentary signal is sent to INPUT 14 the drive indexes until it
receives a signal on INPUT 11. On reception of signal on INPUT 11 the
drive either decelerates and stops or the stop point is delayed for a

4.5 Adjustment of the
Drive
Rated frequency
36
The inverter will output the applied input voltage or the voltage value
adjusted in CP.17 at the frequency value adjusted in this parameter. This
parameter is typically adjusted for the motor rated frequency. Note:
Motors can overheat when the rated frequency is incorrectly adjusted!
The following parameters determine the fundamental
operating data of the drive. They should be checked and/or
adjusted for the application.
In the lower speed range losses in the motor become greater. This
parameter can be used to boost the voltage in order to overcome these
losses. With proper adjustment, the torque output of the motor will remain
constant even at the lowest speeds.
1) Determine the load level (CP.3) with no-load operation at the
rated frequency.
2) Then run at about 10 Hz and adjust the torque boost, so
that about the same load level (CP.3) is achieved as with the
rated frequency.
During continuous operation; if the motor operates at low speed
and too much voltage, it can lead to overheating of the motor.
The parameter determines the time needed to accelerate from 0 Hz to
100 Hz. The actual acceleration time is proportional to the frequency
change (delta f).

The parameter determines the time needed to decelerate from 100 Hz to

The frequency the inverter outputs with 0V applied to the analog input or
if the activated mode frequency is lower than this value.
This function acts as an adjustable current limit during acceleration or
deceleration. It can be used to prevent the load current from exceeding the
inverter's peak current rating, thereby preventing shut down with an E.OC
fault. When the load level reaches the adjusted value, the acceleration
or deceleration is stopped until the load drops below the adjusted value.
Note: if this parameter is adjusted too low, the motor may not be able to
accelerate to full speed. The motor will run at a low speed. CP.2 displays
"LAS" when the function is active.
This function acts as an adjustable current limit when operating at a
constant speed. It can be used to prevent the load current from
exceeding the inverter's over current level, thereby preventing shut
down of the inverter with an E.OC fault. When the load level reaches
the adjusted value, the output frequency is reduced until the load drops
below the adjusted value, after which the frequency is increased again
to the previous value. Setting the value too low may prevent the motor
from running at the desired speed. CP. 2 displays "SSL" when the
function is active.
When starting the frequency inverter into a spinning motor, an E.OC fault
can be triggered because of the difference between the actual motor
speed and the inverter set speed. By activating speed search, the inverter
searches for the actual motor speed, adjusts its output frequency to
match. It will then accelerate with the adjusted ramp time to the given set
value. During speed search CP.2 displays "SSF". This parameter determines under which conditions the function will operate. Parameter values
can be selected individually or any combinations.
Example: CP.16=12 means after reset or after auto-restart (E.UP).

0Function off
1Control release enabled ( terminal 16 )

This parameter can be used to regulate the output voltage in relation to the
rated frequency. With this function active, voltage variations at the input
as well as on the DC bus will have only a small influence on the output
voltage (V/Hz-characteristic). This function can be used to adapt the
output voltage for special motors and can also prevent damage to the
motor resulting from over or under voltage supply.

In the example below using a motor rated at 230 V / 60Hz, the output
voltage is too high due to our supply being 250 V and CP.17 off. By setting
CP.17 to the correct rated motor voltage of 230 V, the voltage is clamped
thereby giving the motor the correct voltage.

Adjustment of the Drive
If the supply voltage drops to190 V and CP.17=230 V, the inverter will still
provide rated voltage to the motor up until 190V. The output voltage can
not be increased further beyond the input therefore the motor will operate
in field weakening. To calculate at which frequency this will occur use the
following formula:
f = (60Hz/ 230 V)*190 V= 50 Hz
CP.17 = 230V V

DC-braking Mode
During DC-braking, the motor is not decelerated by a controlled ramp.
Quick braking without regen voltage can be achieved by applying a DC
voltage to the motor winding. Parameter values listed on the next page,
determine how the DC-braking is triggered.

The positioning function enables the approach of a position with a signal
from different frequencies. With parameter CP.27 the stop position can
be adjusted, which entails an additional constant running time. CP. 27
selects positioning on/off and if positioning is on and additional run time.
This additional run time is added to every speed. In the example below

Diagnosis
KEB COMBIVERT Error messages are always represented with an
"E.xx" and the appropriate error code in the display. Errors cause the
immediate turn off of the output to the motor. Restart is possible, only after
reset.
Malfunctions are represented with an "A.xx" and the appropriate code.
Responses to malfunctions can vary depending on the programmed
condition.
