Preconditions for the performance
•
The wiring of the three motor phases and the feedback must be carried out in accordance
with the specifications from the hardware manual.
•
The motor may be stalled.
•
The servo inverter is error-free and in Switched on device state.
•
Please observe the notes in the Synchronous motor: Pole position identification (PPI) sec-
tion.
Response of the motor during performance
The current test pulses cause audible engine noises that may be increased by the machine
mechanics depending on the mechanical coupling!
How to execute the pole position identification PLI (without movement):
1
.
If the servo inverter is enabled, disable it. Enable operation
2 .
Set the object 0x2825 to "7" to change to the "pole position identification PLI (without
movement)" operating mode.
3 .
Enable the servo inverter to start the process.
Note: Inhibiting the controller serves to abort the started procedure any time if required
without changing the settings.
After the pole position identification has been completed successfully...
...the controller is inhibited automatically and the pole position determined for the activated
feedback system is set in the 0x2C03:002 object.
•
For permanent storage, the changed settings from the servo inverter must be uploaded in
the Controller.
The »EASY Starter« serves to save the parameter settings of the servo inverter as parame-
ter file (*.gdc). Saving the parameter settings
•
The inverter disable set automatically by the procedure can be deactivated again via the
CiA402 control word 0x6040 . Enable operation
Optional settings (starting performance)
Optionally, a pole position identification without motion can be activated after switching on
the servo inverter.

Starting performance (with or without pole position identification before
the start).
0 Deactivated No pole position is identified.
1 Only after 1st enable/encoder error After the first controller enable and after each encoder wire breakage, a
PLI without movement takes place.
CAUTION!
After an encoder wire breakage, the drive may accelerate in an uncon-
trolled manner subsequent to the pole position identification.
•
Cause: In case of a wire breakage, the feedback system state is unde-
fined and the pole position assumes any value.
•
Remedy: Set the error response "Warning" (0x2C45 0x2C45 = 2) for an
encoder wire breakage in order that the pole position will be identi-
fied after a wire breakage.
2 After each enable After every inverter release, the pole position is identified without any
movement.
