Parameter 1-07 Motor Angle Offset Adjust
Table 65: Parameter 1-07 Motor Angle Offset Adjust
1-07 Motor Angle Offset Adjust
Default value: [0] Manual
Parameter type: Option
Setup: All setups
Conversion index: –
Data type: Uint8
Change during operation: False
N O T I C E
This parameter is only valid in combination with a PM motor with feedback.

Name
Description
[0]*
Manual
The functionality of this option depends on the type of the feedback device. This option sets the drive 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 drive automatically adjusts the motor angle offset
on the 1
st
start after power-up, or when the motor data is changed.
[1]
Auto
The drive adjusts the motor angle offset automatically on the 1
st
start after power-up, or when the motor
data is changed no matter what feedback device is selected. This means that the options [1] Manual and
[2] Auto are identical for the incremental encoder.
[2]
Auto every
start
The drive 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 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.
[5]
Auto Every
Start & Run
Rotor angle offset is adjusted at every start and when reducing speed below parameter 1-53 Model Shift
Frequency. Motor control is sensorless above parameter 1-53 Model Shift Frequency using the estimated ro-
tor position as feedback. Below parameter 1-53 Model Shift Frequency the encoder is used as feedback.
Parameter 1-09 Mode of Operation

Data type: Uint8
Change during operation: True
N O T I C E
This parameter is only available with software version 48.8X and newer.
Select mode of operation according to CANopen DS402. This parameter is only active when parameter 1-00 Configuration Mode is
set to [15] Mode of operation.

No mode change
No mode of operation selected. Active mode of operation is velocity mode.

Profile position
mode
Basic positioning mode where the drive profile generator calculates the speed profile based on
set target position, speed and ramps.
