Inverter status display

The 4 parameters below serve to control the frequency inverter during
operation.

Display of the actual output frequency with a resolution of 0.0125 Hz. The
rotation of the inverter is indicated by the sign.

Output frequency 18.3 Hz, rotation forward

Examples:

Output frequency 18.3 Hz, rotation reverse

The status display shows the actual working conditions of the inverter.
Possible displays and their meanings are:

" no Operation " control release (terminal X1.14) not
bridged, modulation switched off, output voltage = 0 V,
drive is not controlled.

" Low Speed " no rotation preset ( terminal X1.12 or
X1.13), modulation switched off, output voltage = 0 V,
drive is not controlled.

" Forward Acceleration " drive accelerates with a forward
direction of rotation.

Actual load

Peak load

" Forward Deceleration " drive decelerates with a forward
direction of rotation.

" Reverse Acceleration " drives accelerates with a reverse
direction of rotation.

" Reverse Deceleration " drive decelerates with a reverse
direction of rotation.

" Forward Constant " drive runs with a constant speed
and a forward direction of rotation.

" Reverse Constant " drive runs with constant speed and
a reverse direction of rotation.

Other status messages are described at the parameters, which they cause.

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
regenerative operation.

This display makes it possible to recognize short-term fluctuations of the
rate of utilization by storing the highest value that occurred. The display
occurs in percent (100% = inverter rated current).

4.5 Basic Adjustment
of the Drive

Rated frequency

Boost

The following parameters determine the fundamental operating data of
the drive. They should be checked and/or adapted to the application.

With the adjusted frequency here the inverter reaches a maximal output
voltage. The adjustment of the motor rated frequency is typical here.
Note: Motors can overheat when the rated frequency is incorrectly
adjusted!

Factory setting: 50.0 Hz
Customer adjustment: _______ Hz

CP. 5

f

In the lower speed range a large part of the motor voltage decreases on
the stator resistance. In order that the breakdown torque of the motor
remains almost constant in the entire speed range, the voltage decrease
can be compensated by the boost.

U

Factory setting: 2.0 %
Customer adjustment: _______ %

CP. 6

CP. 5

f

Adjustment: - Determine the rate of utilization in no-load operation during

rated frequency

- Preset about 10 Hz and adjust the boost, so that about the
same rate of utilization is reached as with the rated frequency.

When the motor, during continuous operation, drives with low
speed and too high voltage it can lead to an overheating of the
motor.

GB

Acceleration time

The parameter determines the time needed, in order to accelerate from
0 to 100 Hz. The actual acceleration time is proportional to the frequency
change.

4.6 Special
Adjustments

Max. ramp current

Max. constant current

The following parameters serve to optimize the drive and adaption onto
certain applications. These adjustments can be ignored at the initial startup.

This function protects the frequency inverter against switching off by
overcurrent during the acceleration ramp. When the ramp reaches the
adjusted value here, then it is stopped as long as the current decreases
again. CP.2 displays "LAS" at active function.

Adjustment range:10...200%, 200% = oFF
Resolution: 1 %
Factory setting: 140 %
Customer adjustment: _______ %

This function protects the frequency inverter against switching off due to
overcurrent during constant output frequency. When exceeding the
adjusted value here, the output frequency is reduced until the value drops
below the adjusted value. CP. 2 displays "SSL" at active function.

Speed search

Voltage stabilization

When connecting the frequency inverter onto a decelerating motor, an
error can be triggered by the differing rotating field frequencies. At
activated speed search the inverter searches the actual motor speed,
adapts its output frequency and accelerates with the adjusted ramp onto
the given set value. During speed search CP.2 displays "SSF". The
parameter determines, under what conditions the functions operate. With
several conditions the sum of the value must be entered.
Example: CP.16 = 5 means at control releas and after reset

Adjustment range: 0...7 Value Condtion
Resolution: 1 0 function off
Factory setting: 0 1 at control release
Customer adjustment: _______ 2 at switch on

4 after reset

This parameter can adjust a regulated output voltage in relation to the
rated frequency. Because of this voltage variations at the input as well as
in the intermediate circuit only have a small influence on the output voltage
(U/f-characteristic). The function allows, among other things, an adaption
of the output voltage onto the special motors. In the example below the
output voltage is stabilized onto 230 V (0% boost).

Adjustment range:150...649 V, oFF

Slip compensation

Autoboost

Slip compensation balances the speed changes caused by the load
variation. In order to activate the function, set the value at 1.00 and
optimize as directed in the examples below.

Adjustment range: -2.50...2.50
Resolution: 0.01
Factory setting: 0.00 (= oFF)
Customer adjustment: _______

GB

Autoboost causes an automatic I*R-compensation by raising the output
voltage during high load torques. The magnetizing current remains
constant. To activate the function set the value to 1.00 and optimize as
directed in the examples below. Check the motor voltage to see, whether
it returned to the normal value after no load of the drive. Otherwise reduce
CP.19.

Adjustment range: -2.50...2.50
Resolution: 0.01
Factory setting: 0.00 (= oFF)
Customer adjustment: _______

Slip compensation and autoboost work on the basis of preset
motor data. When using a special motor or in case of
overdimensioning of more than one size, then both functions
should be deactivated.

With DC-braking the motor is not decelerated by the ramp. Quick braking
is caused by DC 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 in

reaching 0Hz. Braking time is dependent on CP.21 or until
the next direction of rotation presetting.

2 DC-braking as soon as the direction of rotation presetting

is absent. Braking time dependent on the real frequency

3 DC-braking, as soon as the direction of rotation changes.

Braking time dependent on the real frequency.

4 DC-braking at switch off of the direction of rotation and the

real frequency goes below 4 Hz.
5 DC-braking, when the real frequency goes below 4 Hz.
6 DC-braking, as soon as the set value goes below 4 Hz.
7 DC-braking deactivated
8 DC-braking deactivated
9 DC-braking after switching on the modulation on. Braking

time is dependent on CP.21.

Braking time

4.7 The Drive Mode The drive mode is a operating mode of KEB COMBIVERT to start the

drive manually by the operator. After switching the control release the set
value and rotation presetting is done exclusively by the keyboard. In order
to activate the drive mode the corresponding password in CP.0 must be
entered. The display switches over as follows.

Error messages are represented with an "E. " and the corresponding
error in the display of the KEB COMBIVERT. The displays and their
causes are described below.

Occurs, when the intermediate ciruict voltage falls below the permissible value.
Possible causes are - input voltage too low or unstable

- inverter power too small

- voltage loss due to incorrect cabling

- power supply by generator/transformer breaks down,
because ramps are too short

GB

Occurs, when the intermediate circuit voltage rises above over the
permissible value.
Possible causes are - input voltage too high

- disturbance voltages at the input

- delay ramps too short

Occurs, when exceeding the peak current or at ground fault.

Occurs when a too high load is applied for more than the allowed time
(see "Performance Data"). Possible causes for this are

- error or overload in the application

- inverter incorrectly dimensioned

- motor incorrectly wired

Cooling down phase

completed

Overheat

no Overheat

Current limit resistor error

After error E. OL you must wait for a cooling down time. This message
appears after the cooling down phase is completed. The error can be
reset.

Occurs, when the heat sink temperature > 85°C. Possible causes for this
are - insufficient cooling

- surrounding temperature too high

Internal or external excess-temperature error do not occur anymore.
Error "E. OH" can be reset.

Current limit resistor not bridged, occurs for a short time during the turn on
phase and is reset immediately. If the erorr message remains the following
may be the cause - incorrect or input voltage too small

- high loss in the supply line
