Identification of all parameters in standstill
Dependency: No measurement if motor data incorrect.
P1900 = 2: Calculated value for stator resistance (see P0350) is overwritten.
Notice:
When the identification is finished P1900 is set to 0. When choosing the setting for measurement, observe
the following:
The value is actually adopted as P0350 parameter setting and applied to the control as well as being
shown in the read-only parameters below. Ensure that the motor holding brake is not active when per-
forming the motor identification.
Note:
Before selecting motor data identification, "Quick commissioning" has to be performed in advance.
Since the cable length of the applications differs in a wide range, the preset resistor P0352 is only a rough
estimation. Better results of the motor identification can be achieved by specifying the cable resistor be-
fore the start of the motor identification by measuring/calculating.
Once enabled (P1900 > 0), A541 generates a warning that the next ON command will initiate measure-
ment of motor parameters.
Communications - both via USS as well as via the Modbus - are interrupted for the time that it takes to
make internal calculations. These calculations can take up to one minute to complete.
