Otherwise the drive remains in dr02 = 3 "error norm motordata“ and the identifica-
tion cannot be carried out.
To use the identification, an operating mode with motor model must be selected in
cs00 control mode (cs00 bit 0...3 = 2 or 3) and the inverter may not be in error
state, otherwise the input is rejected by dr54.
The determination of the resistance and inductance occurs in standstill (slight rota-
tion of the motor is possible by test signals).
For the determination of dr14 SM EMF, the drive must be in standstill or must be
able to rotate only with small load.
The speed is determined by dr44 in % rated speed. The value must be changed if
the application requires another (lower) speed. Forward direction of rotation.
The motor data and the parameterization of the identification are stored with dr99 =
0. Value 2 "motordata stored" must be displayed in dr02.
Parameterize encoder
If an operating mode with encoder is selected, the encoder parameters must be
adjusted in the ec group (encoder type, smoothing, etc.). More information about
encoder parameterization can be found in chapter 6.1 Interface to the encoder.
At the end of a successful parameterization the value of ec00 status encoder inter-
face must be = 9 "position value ok“.
Prepare system position-identification
The knowledge of the system position is mandatory necessary for the operation of
a synchronous motor (also called systemoffset). The following cases must be dif-
ferentiated: Operation with encoder => system position measurement is checked
by dd00 Operation without encoder (SCL) => system position measurement is
checked by dd01
For SCL operation, dd01 is set to the correct value after default loading (point 2).
dd00 must be set to value 1 for the operation with encoder, by way that the system
position adjustment is executed with the following identification.
Identify
The drive must be ready for operation in order to identify:
• The DC link must be loaded.
• ru01 exception state must be equal to 0 "no exception“ (if an error message is
present, the cause must be removed and a reset must be executed with co00 =
128).
• The corresponding inputs must be set if the drive has safety functionality.
• The ramps (co48…co60) must be parameterized by way that no excessive ac-
celeration forces occur.
• The speed controller has been adjusted already automatically if the inertia in
dr32 nd cs17 has been correctly parameterized. Otherwise, the inertia must be
preset in terms of magnitude and the automatic adjustment must be carried out
by writing on cs99. Alternatively cs99 can be set to 19 "off“ and the speed
controller can be adapted manually.
• The torque and current limits are set to 100% (default).
