10.9 Automatic detection of motor data
This function serves to detect the required motor data and the motor cable
influences.
Must be done before the first commissioning of vector control (C0014 = 4) or
sensorless torque control (C0014 = 5). Otherwise commissioning is not possible.
)
))
) Note!
The motor parameter identification influences the smooth running
behaviour in the control mode ”V/f characteristic control with
constant U
min
boost” (C0014 = 2 or 3). If you identify the motor
parameters for this control mode, you can optimise the smooth
running behaviour for low speeds.
