Installation and Connection
When running the inverter without an operator, it runs with the last
storedvaluesorfactory setting.The redLEDremains onconstantly
when the unit is connected to supply voltage and functioning nor-
mally. The LED will begin to flash in the event of an error condition.
Tofacilitateparameteradjustmentandinvertermonitoring,akeypad/
display operator is required. To prevent malfunctions, the inverter
must be brought into nOP status before connecting/disconnecting
the operator (remove the signal at the control release terminal 14).
The operator is available in different versions:

With UP( ) andDOWN ( )the
value of the parameter number is
increased / decreased .
Generally, when a value is changed, parameter values are immediately
accepted and stored nonvolatile. With some parameters it is necessary to press
ENTER after changing the value in order for the new value to be stored
nonvolatile. When this type of parameter is changed, a decimal point appears
behind the last digit.
If a drive fault occurs during operation, the current display changes to the fault

2.3 Password input From the factory, the frequency inverter is supplied without
password protection, this means that all parameters can be
adjusted. After programming, the unit can be protected
against unauthorized access thus preventing the values
from being changed.
See the last page for the
actual password values.

The 4 parameters below can be used to monitor the frequency inverter's
operation.
Displayoftheactualoutputfrequencywitharesolutionof0.0125Hz.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 14) not con-
nected, modulation switched off, output voltage = 0 V,
drive is disabled.
"LowSpeed"norotationsignalForR(terminal12or13),

2.5 Basic adjustment
of the drive 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 over come these
losses. With proper adjustment, the torque output of the motor will
remain constant even at the lowest speeds.
Adjustment range: 0...25.5 %
Resolution: 0.1 %
Factory setting: 2.0 %
Customer adjustment: _______ %
Adjustment: - Using CP.3, determine the load level during no-load
operation at the rated frequency
- Run the motor at 10 Hz and adjust the boost, so that the
same load level occurs as at the rated frequency.
- Whenthemotorrunsatlowspeedscontinuously withtoo
much boost, overheating of the motor can result.
This parameter determines the time required to accelerate from 0 to
100 Hz. The actual acceleration time is proportional to the change in
frequency. See below.
change in frequency x CP.7
actual acceleration time = 100 Hz
Adjustment range: 0.01...300 s
Resolution: 0.01 s
Factory setting: 10 s
Customer adjustment: _______ s
Example: CP. 7 = 10 s ; the drive accelerates from 10 Hz to 60 Hz
change in frequency = 60 Hz - 10 Hz = 50 Hz
actual acceleration time = (50 Hz / 100 Hz) x 10s = 5 s
