Installation and Connection
As an accessory to the local operation an operator is necessary. To
prevent malfunctions, the inverter must be brought into nOP status
before connecting/disconnecting the operator (open control release
terminal X1.14). When starting the inverter without an operator, it is
started with the last stored values or factory setting. The operator is
obtainable in different versions:

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.
"Forward Deceleration " drive decelerates with a forward
direction of rotation.
"Reverse Acceleration " drivesaccelerateswith a reverse
direction of rotation.
"ReverseDeceleration"drivedecelerateswithareverse
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).
With the UP or DOWN key the peak value can be reset when the
unit is on. Switching off the unit deletes the peak value.

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.
Adjustment range: 0...25.5 %
Resolution: 0.1 %
Factory setting: 2.0 %
Customer adjustment: _______ %
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
samerateofutilizationisreachedaswiththeratedfrequency.
When the motor, during continuous operation, drives with low
speed and too high voltage it can lead to an overheating of the
motor.
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 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.

Operation of the Unit
Speed search 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

Voltage stabilization 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).

Slip compensation 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: _______
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.
