7-33 Process PI Proportional Gain
Option:
Function:
[0.01]
*
0.00-10.00 Enter the value for the P proportional gain,
i.e. the multiplication factor of the error
between the set point and the feedback
signal.
NOTE
0.00=Off.
7-34 Process PI Integral Time
Range:
Function:
9999.00 s
*
[0.10-9999.00 s] The integrator provides an
increasing gain at a constant error
between the set point and the
feedback signal. The integral time
is the time needed by the
integrator to reach the same gain
as the proportional gain.
7-38 Process Feed Forward Factor
Range:
Function:
0%
*
[0-400%] The FF factor sends a part of the reference
signal around the PI controller which then only
affects part of the control signal.
By activating the FF factor less overshoot and
high dynamics are gained when changing the
setpoint.
This parameter is always active when

7.5 Main Menu
[Main Menu] is used for programming all parameters. The
Main Menu parameters can be accessed immediately
unless a password has been created via
0-60 Main Menu
Password
. For most VLT
®
Micro Drive applications it is not
necessary to access the Main Menu parameters but instead
the Quick Menu provides the simplest and quickest access
to the typical required parameters.
The Main Menu accesses all parameters.

7.6 Quick Transfer of Parameter Settings
between Multiple Frequency Converters
Once the set-up of a frequency converter is complete,
Danfoss recommends to store the data in the LCP or on a
PC via MCT 10 Setup Software tool.
Data storage in LCP.
WARNING
Stop the motor before performing this operation.
1.
Go to
0-50 LCP Copy
2.
Press the [Ok] key
3.
Select “All to LCP”
4.
Press the [Ok] key
Connect the LCP to another frequency converter and copy
the parameter settings to this frequency converter as well.
Data transfer from LCP to frequency converter:
NOTE
Stop the motor before performing this operation.
1.
Go to
0-50 LCP Copy
2.
Press the [Ok] key
3.
Select “All from LCP”
4.
Press the [Ok] key
7.7 Read-out and Programming of Indexed
Parameters
Use as an example.
Press [Ok] for selecting a parameter and use [

maneuvering between the indexed values.
To change the parameter value, select the indexed value
and press [OK].
Change the value using [
▲

].
Press [Ok] to accept the new setting.
Pressing [Ok] for more than 1 s enters 'Adjust' mode. In
'Adjust' mode, it is possible to make fast adjustment by
pressing [
