Normal
torque
For oversized motor - allows up to 110% over
torque.
1-05 Local Mode Configuration
Option:
Function:
Select which application configuration
mode (
parameter 1-00 Configuration Mode
),
that is application control principle, to use
when a local (LCP) reference is active. A
local reference can be active only when
is set to
[0]
Linked to Hand/Auto
or
[2] Local
. By default
the local reference is active in hand-on
mode only.

1-06 Clockwise Direction
Option:
Function:
NOTICE
This parameter cannot be adjusted while
the motor is running.
This parameter defines the term clockwise
corresponding to the LCP direction arrow. Used for
easy change of direction of shaft rotation without
swapping motor wires.

1-07 Motor Angle Offset Adjust
Range:
Function:
NOTICE
This parameter is only valid for FC 302
and only in combination with a PM motor
with feedback.
0
*
[Manual] The functionality of this option depends on the
type of the feedback device. This option sets the
frequency converter to use the motor angle
offset entered in
, if an absolute feedback device is used.
1-07 Motor Angle Offset Adjust
Range:
Function:
If an incremental feedback device is selected, the
frequency converter automatically adjusts the
motor angle offset on the first start after power-
up, or when the motor data is changed.
[1] Auto
The frequency converter adjusts the motor angle
offset automatically on the first start after power-
up, or when the motor data is changed no
matter what feedback device is selected. This
means that options
Manual
and
Auto
are
identical for the incremental encoder.
[2] Auto
Every
Start
The frequency converter adjusts the motor angle
offset automatically on every start, or when the
motor data is changed.
[3] Off
Selecting this option turns the automatic offset
adjustment off.
[4] Once with
Store
This option updates
automatically when the angle value is 0.
This option is valid only for absolute feedback
devices. The function uses rotor detection and
then applies DC hold to make the offset
adjustment more accurate.
3.2.2 1-1* Special Settings
NOTICE
The parameters within this parameter group cannot be
adjusted while the motor is running.
3.2.3 Asynchronous Motor Set-up
Enter the following motor data. Find the information on
the motor nameplate.
1.
Parameter 1-20 Motor Power [kW]
or
parameter 1-21 Motor Power [HP]
.
2.
Parameter 1-22 Motor Voltage
.
3.
Parameter 1-23 Motor Frequency
.
4.
Parameter 1-24 Motor Current
.
5.
Parameter 1-25 Motor Nominal Speed
.
When running in flux control principle, or for optimum
performance in VVC
+
mode, extra motor data is required to
set up the following parameters. Find the data in the
motor datasheet (this data is typically not available on the
motor nameplate). Run a complete automatic motor
adaptation (AMA) using
parameter 1-29 Automatic Motor
Adaptation (AMA)
[1] Enable Complete AMA
or enter the
parameters manually.
Parameter 1-36 Iron Loss Resistance
(Rfe)
is always entered manually.
