Optimising motor parameter identification
For the measurement of the required variables, the motor is energised via the controller
terminals U, V and W during the motor parameter identification.
The corresponding current controller can be set via the following parameters:
In the Lenze setting, the current controller is preset in such a way that an optimum
controller behaviour is obtained for an asynchronous motor with power adaptation to the
controller.

Note!
The motor parameter identification can be aborted in the following cases:
• If a special motor (e.g. mid-frequency motor) or a servo motor is used.
• If there is a large deviation between inverter and motor power.
In this case we recommend (with the simple motor parameter identification):
• to reduce the P component Vp of the current controller (
C00075
) e.g. by
halving.
• to increase the time constant Ti of the current controller (
C00076
) e.g. by
doubling.
With the extended motor parameter identification, the current controller
parameters are determined automatically. If the identification is aborted all the
same, the current controller parameters set in
C00075
and
C00076
can be used
by parameterising
C02866
to "1".
Another cause for the abort of the motor parameter identification could be the
implausibility of the entered nameplate data, e.g. the entry P = 0 kW for the
motor power.
