Preconditions for the execution
• The three motor phases and the motor encoder have to be wired according to the specifications
given in the i700 hardware manual.
• The motor may be firmly braked.
• The servo inverter is free of errors and is in the "Switched on
" device status.
• Please observe the notes from the Selection criteria for using the suitable pole position
identification section.
Response of the motor during the execution
The current test pulses cause audible engine noises that can be increased by the machine mechanics
depending on the mechanical coupling!
 How to execute the pole position identification (without movement):
1. If the servo inverter is enabled, inhibit the servo inverter.
Enable/inhibit operation via control word
( 52)
2. Set object 0x2825
(or 0x3025 for axis B) to "7" to change to the "Pole position identification
PPI (without movement)" operating mode.
3. Enable the servo inverter to start the procedure.
Note: By means of controller inhibit, the procedure started can be cancelled any time, if
required, without a change in settings.
After successful completion of the pole position identification...
...controller inhibit is set automatically and the pole position specified in object 0x2C03:2
(or
0x3403:2
for axis B) for the activated feedback system is set.
• For permanent storage, the changed settings must be uploaded to the controller from the i700
servo inverter.
The »EASY Starter« serves to save the parameter settings of the i700 servo inverter as parameter
file (*.gdc). In the »PLC Designer«, this file can then be imported in the corresponding axis.
