5.1.2 Automatic motor data identification
Via the "Identify motor parameters" device command (C00002/23
), the inverter
characteristic, the influences of the motor cable, and the motor parameters listed in the
table below can be identified automatically:

 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!
 Note!
• We strongly recommend motor parameter identification before the initial
commissioning of the sensorless vector control (SLVC).
• 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.
