Basic commissioning: Motor identification
Selecting motor identification
To navigate through the selection fields,
choose <F2> or <F3>.
To activate a selection, choose <F5>.
Stationary measurement increases the co
n-
trol performance, as this minimizes devi
a-
tions in the electrical characteristic values
due to var
iations in material properties and
manufa
cturing tolerances.
Rotary measurement determines the data
required (e.g., moment of inertia) for setting
the speed controller. It also measures the
magnetization characteristic and rated ma
g-
netization current of th
e motor.
Changing the number of phases to be ident
i-
fied:
•
For identification with one phase, the
measurement time is significantly
reduced.
•
For identification with several phases, the
measurement results are averaged.
To activate this function, press the LO
CAL
key (wait until the LED in the LOCAL key
lights up) and then ON.
If motor identification is not carried out, the
motor control uses the motor characteristic
values calculated from the rating plate data
rather than the measured values.
Note
Complete motor identification
When motor identification has been completed, press the OFF key to cancel the power
-on
inhibit.
