Maximum output voltage (effective value)
Identification
6.2.18.1 Function
Motor parameters, which are not specified on the type plate or in the data sheet
can be determined with the identification.
The dead-time characteristic of the inverter can be determined additionally.
Condition for starting the identification is the correct input of the motor type and
rated current, rated voltage, rated speed and rated frequency.
Presettings for the controller and limitations for the test signals are determined
from this data.
Also the encoder parameters (type, increments, etc.) must be preset at speed con-
trol with encoder.
The identification determines the following motor data:
Asynchronous machine
Rotor resistance in % of the stator resistance
Stator leakage inductance in mH
Rotor leakage inductance in % of the stator value
EMC (peak value of the phase-to-phase voltage) at
1000 rpm in V
Cross inductance (inductance q-axis) in mH
Series inductance (inductance d-axis) in % of dr15.
Either all or only single motor parameters can be identified.
The automatic mode (mode 1 or 2 "all") is the simplest method of parameter identi-
fication.
Single identifications should not be used for the first measurement of the motor pa-
rameters, since wrong measurement results can occur with wrong identification or-
der or missing of single points.
The single identification can always be used if a complete automatic measurement
has been executed and only single parameters should be identified new. This can
