Parameter Descriptions
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.
[0] Normal The motor shaft turns in clockwise
*
direction when the frequency
converter is connected U⇒U, V⇒V,
and W⇒W to the motor.
[1] Inverse Motor shaft turns in counter-
clockwise direction when the
frequency converter is connected
U⇒U, V⇒V, and W⇒W to the motor.

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
parameter 1-41 Motor Angle Offset, if
an absolute feedback device is
used.
If an incremental feedback device is
selected, the frequency converter
automatically adjusts the motor
angle offset on the 1
power-up, or when the motor data
is changed.
[1] Auto The frequency converter adjusts the
motor angle offset automatically on
the 1
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.

1-07 Motor Angle Offset Adjust
Range: Function:
[2] Auto Every The frequency converter adjusts the
Start 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 This option updates
Store parameter 1-41 Motor Angle Offset
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.
•
Parameter 1-20 Motor Power [kW] or
parameter 1-21 Motor Power [HP].
•
Parameter 1-22 Motor Voltage.
•
Parameter 1-23 Motor Frequency.
•
Parameter 1-24 Motor Current.
•
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.
•
Parameter 1-30 Stator Resistance (Rs).
•
Parameter 1-31 Rotor Resistance (Rr).
•
Parameter 1-33 Stator Leakage Reactance (X1).
•
Parameter 1-34 Rotor Leakage Reactance (X2).
•
Parameter 1-35 Main Reactance (Xh).
•
Parameter 1-36 Iron Loss Resistance (Rfe).
