Motor control (MCTRL)
Motor selection/Motor data
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
motor 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 ( 117)
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.
