Auto setup
To determine a number of parameters related to the motor and the connected sensors (encoders/Hall sensors), you must perform an auto setup.
Tip:
As long as the motor connected to the controller or the sensors for feedback (encoders/Hall sensors) are not changed, auto setup is only to be performed once during initial commissioning.
Note:
Tip: Execution of the auto setup requires a relatively large amount of processor computing power. During the auto setup, this may result in fieldbuses not being operated in a timely manner.
Note: With the Plug & Drive motors, it is not necessary to perform an auto setup, as this was already performed at the factory. An exception occurs if an external encoder is connected to X2.
Parameter determination
Auto setup determines various parameters of the connected motor and of the present sensors by means of multiple test runs and measurement runs. To a certain extent, the type and number of parameters are dependent on the respective motor configuration.
Parameter | All motors independent of the configuration |
---|---|
Motor type (stepper motor or BLDC motor) | ✓ |
Winding resistance | ✓ |
Winding inductance | ✓ |
Interlinking flux | ✓ |
Note: It is not possible to determine the interlinking flux on motors whose windings have widely differing inductances. These motors are, therefore, not suitable for sensorless closed-loop operation.
Parameter | Motor without encoder | Motor with encoder and index | Motor with encoder without index |
---|---|---|---|
Encoder resolution | - | ✓ | --- |
Alignment (shifting of the electrical zero to the index) | - | ✓ | --- |
Parameter | Motor without Hall sensor | Motor with Hall sensor |
---|---|---|
Hall transitions | - | ✓ |
Execution
Parameter memory
After a successful auto setup, the determined parameter values are automatically taken over into the corresponding objects and stored with the storage mechanism, see Saving objects and 1010h Store Parameters. Categories Drive 1010h:05h and Tuning 1010h:06h are used.
