4.2 Parameter Group 1: Load/Motor
1-00 Configuration Mode
Option:
Function:
Use this parameter for selecting the
application control principle to be used when
a Remote Reference is active.
NOTE
Changing this parameter will reset
3-00
Reference Range
,
3-02 Minimum Reference
and
3-03 Maximum Reference
to their
default values.
NOTE
This parameter cannot be adjusted
while motor runs.
[0 ]
*
Speed
Open Loop
For normal speed control (References).
[3]
Process
Closed
Loop
Enables process closed loop control. See
parameter group
7-3* Process PI Control
for
further information on PI-controller.
1-01 Motor Control Principle
Option:
Function:
[0]
U/f
Is used for parallel connected motors and/or special
motor applications. The U/f settings are set in
1-55
U/f Characteristic -U
and
1-56 U/f Characteristic -F
.
NOTE
When running U/f control slip- and load
compensations are not included.
[1]
*
VVC+ Normal running mode, including slip- and load
compensations.
1-03 Torque Characteristics
Option:
Function:
With more torque characteristics it is
possible to run low energy consuming, as
well as high torque applications.
[0 ]
*
Constant
Torque
Motor shaft output provides constant
torque under variable speed control.
[2]
Automatic
Energy Optimi-
sation
This function automatically optimizes
energy consumption in centrifugal pump
and fan applications. See
14-41 AEO
Minimum Magnetisation
.
1-05 Hand Mode Configuration
Option:
Function:
This parameter is only relevant when
1-00
Configuration Mode
is set to
[3] Process Closed
Loop
. The parameter is used for determining
the reference or setpoint handling when
changing from Auto Mode to Hand Mode on
the LCP.
[0]
Speed
Open
Loop
In Hand Mode the drive always runs in Open
Loop configuration regardless of setting in
1-00
Configuration Mode
. Local potentiometer (if
present) or Arrow up/down determines output
1-05 Hand Mode Configuration
Option:
Function:
frequency limited by Motor Speed High/Low
Limit (
4-14 Motor Speed High Limit
and
4-12
Motor Speed Low Limit
).
[2]
*
As config-
uration in
1-00
Configu-
ration
Mode
.
If
1-00 Configuration Mode
is set to
[1] Open
Loop
function is as described above.
If
1-00 Configuration Mode
is set to
[3] Process
Closed Loop
changing from Auto mode to Hand
mode results in a setpoint change via local
potentiometer or Arrow up/down. The change
is limited by Reference Max/Min (
3-02 Minimum
Reference
and
3-03 Maximum Reference
).
4.2.1 1-2* Motor Data
Enter the correct motor nameplate data (power, voltage,
frequency, current and speed).
Run AMT, see
1-29 Automatic Motor Tuning (AMT)
.
Factory settings for advanced motor data, parameter group
1-3* Adv. Motor Data
, are automatically calculated.
NOTE
Parameters in parameter group
1-2* Motor Data
cannot be
adjusted while motor runs.
1-20 Motor Power [kW]/[HP] (P
