6.2 Motor parameterization
General
An assistent for start-up-support is integrated in Combivis 6.
Each parameter input in the dr group is only stored if parameter dr99 "motordata
control“ is written.
store motor-
data, init reg.
The new motor data are transferred and initialization
of all standardizations
store motor-
data, no reg.
The new motor data are transferred, but the follow-
ing parameters are not recalculated:
current controller (ds00…ds03) / flux controller
(fc18, fc19) /
filter time for the stabilization (ds33)
store motor-
data, calc e.c.d.
(ASM)
The equivalent circuit data for the asynchronous
machine (ASM) are determined from the nameplate
data. dr99 is set to ZERO after calculation.
The following parameters are calculated:
Main inductance (Lh)
Stator leakage inductance (sLs)
Rotor leakage inductance (sLr)
Stator resistance (Rs)
Rotor resistance (Rr)
Boost (Uboost)
If a parameter is changed manually, which is only calculated automatically at mo-
tordata control = 0 (e.g., current controller gain), dr99 is set automatically to value
1.
The status can be read in parameter dr02 motordata state.
Modulation release is not possible in status "fill motordata“ and "storing motordata“.
If the drive is set to state "operation enabled" nevertheless, it changes to "ERROR
motordata not stored“ (ru01 = 21).
This error can only be reset when the data are transferred with dr99. dr-parameters
can be changed and activated by writing on dr99 while the drive is in state "opera-
tion enabled".
