Pre-adjustment of the main inductance (dr.48 = 1)
With dr.48 = 1 (calculation of the main inductance (ASM) / EMC(SM)), a starting value for the main inductance
is calculated from the rating plate data.
Leakage inductance measurement (dr.48 = 2)
Measurement of the leakage inductance (dr.07) occurs at standstill with a test signal. The frequency of the
measuring signal is adjustable via bit 5...7 in parameter dr.48.
Since the inverter determines automatically the ideal measuring frequency, value 0 should be always selected
for bits 5... 7.
Stator resistance measurement (dr.48 = 3)
Measurement of the stator resistance is done with DC current.
Rotor resistance measurement (dr.48 = 4)
Measurement of the rotor resistance (dr.08) occurs at standstill with a test signal. The frequency of the measu-
ring signal is adjustable via bit 5...7 in parameter dr.48.
Since the inverter determines automatically the ideal measuring frequency, value 0 should be always selected
for bits 5... 7.
Since the measurement frequency occasionally has to be reduced to 7.8125 Hz for better measurement accu-
racy, the motor may rotate.
Model / controller parameterization (dr.48 = 5)
With dr.48 = 5, the internal model parameters as well as current-, ux- and speed calculation controller parame-
ters are calculated from the equivalent circuit data. If a mode other than automatic is used for the identication,
this action should be executed after the measurement of the leakage inductance, rotor and stator resistance,
but before the identication of the main inductance, in order that the controllers are correctly parametrised for
the speed ramp-up.
