Description
Status information related to the position counter function.
See section Position counter
This parameter is read-only.
Value
1 = Encoder 1 selected as load feedback source
1 = Encoder 2 selected as load feedback source
1 = Internal load position estimate selected as load feedback source
1 = Motor feedback selected as load feedback source
0 = Position counter not initialized, or encoder feedback was lost.
Fresh counter initialization recommended.
1 = Position counter successfully initialized
1 = Position counter initialization is being prevented by par.
1 = Encoder feedback intermittent or lost. (If the drive is running,
estimated position is used whenever encoder feedback is
unavailable. If the drive is in stopped state, position counting will
continue based on encoder data after the connection is restored.)
Position counter status word.
Scales the values of parameters
and 90.65 Pos counter init value
from an external source (eg. fieldbus). The setting
corresponds to the number of decimal places.
For example, with the setting of 3, an integer value of 66770
written into 90.65 Pos counter init value
the final value applied will be 66.770. Likewise, the value of
90.05 Load position scaled
Number of position counter decimal places.
Selects the motor speed feedback value used during motor
control.
Note: With a permanent magnet motor, make sure an
autophasing routine (see page 96) is performed using the
selected encoder. If necessary, set parameter
requested to Autophasing
routine.
A calculated speed estimate generated from the DTC core is
used.

90.05 Load position scaled
when written from or read to
