These parameters are useful for non-standard motors,
or to just get more accurate motor control of the motor
on site. A better motor model always improves the
shaft performance.
Not selected / uint16Activates the motor model parameters 98.2 … 98.14
and the rotor angle offset parameter 98.15.
User motor model
mode
98.1
Note: Parameter value is automatically set to zero when
ID run is selected by parameter 99.13 ID run requested.
The values of parameters 98.2 … 98.15 are then updated
according to the motor characteristics identified during
the ID run.
Note: Measurements made directly from the motor
terminals during the ID run are likely to produce slightly
different values than those on a datasheet from a
motor manufacturer.
Note: This parameter cannot be changed while the
drive is running.
0The values detected during the ID run are being used.Not selected
1The values of parameters 98.2 … 98.14 are used in the
motor model.
Motor parameters
2The value of parameter 98.15 is used as the rotor angle
offset. Parameters 98.2 … 98.14 are inactive.
Position offset
3The values of parameters 98.2 … 98.14 are used in the
motor model, and the value of parameter 98.15 is used
as the rotor angle offset.
