 Danger!

During motor parameter identification, the motor is energised via the outputs U, V and

W of the controller!

Observe the corresponding safety instructions!

 Stop!

• If motor parameter identification is aborted, unstable drive behaviour may be the

result!

• The following applies to the motor parameter identification of synchronous motors:

• Only the extended

motor parameter identification can be used.

• During the motor parameter identification, the shaft of the synchronous motor

mus rotate freely (must not be locked).

• During motor parameter identification, rotations take place.

• For asynchronous motors as of a power of 11 kW, the following applies:

• Only the extended

motor parameter identification can be used.

• When the extended motor parameter identification is started, it is decided based on

the motor control selected in C00006

whether an asynchronous or a synchronous

motor is to be identified.

• Thus, set a suitable motor control for the motor in C00006

before starting the

extended motor parameter identification! Selecting the control mode

 Note!

• We strongly recommend motor parameter identification before the initial

commissioning of the sensorless vector control (SLVC) and the sensorless control for

synchronous motors (SLPSM).

• The motor parameter identification must be carried out when the motor is cold!

• The load machine may remain connected. Holding brakes, if present, may remain in

the braking position.

• With an idling motor, a small angular offset may occur at the motor shaft.

• The amplitude of the rated motor current (C00088

) is injected to identify the stator

resistance. If the rated motor current amounts to less than 60 % of the rated inverter

current, at least 60 % of the rated inverter current will be injected to ensure sufficient

motor parameter identification accuracy.
