4.2.21 Identify pole position (min. motion)
If no absolute value encoder is connected, or a synchronous motor of a third-party manufacturer is
driven by the controller, the C00002 = "52: Identify pole position (min. motion)" device command is
used to determine the pole position with respect to the motor encoder currently activated in
C00495 .
• The function can only be activated if the controller is inhibited. Then the execution of the
function starts automatically as soon as the controller inhibit is deactivated again.
• During the pole position identification, the rotor aligns itself. This is compensated by a position
control.
• The determined pole position is indicated under code C00058 .

Tip!
Detailed information on the pole position identification can be found in the chapter "Motor
interface", subchapter " Pole position identification ". ( 128)
Possible status displays for this device command

Note!
From software version V4.0 the response parameterised in C00640 (Lenze setting:
"Fault") is triggered and the error message "Pole position identification cancelled" is
entered in the logbook of the controller if the pole position identification process is
aborted.
Status ( C00003 ) Meaning
3441922 Device command in process
3407872 Device command executed successfully
3407873 General fault
3447559 Pole position identification cannot be executed because of wrong motor type (asynchronous
motor).
3447560 Pole position identification has been aborted
3447561 Pole position identification cannot be executed because another identification is already
active.
3447562 Identification of pole position cannot be executed because U-rotation or I-rotation test
mode is active.
3447563 Identification of pole position cannot be executed because current controller optimisation
mode is active.
3447569 Pole position identification cannot be executed because the motor is blocked (e.g. by a
mechanical brake), a motor phase is not connected, or a phase shifter is in the motor cable.
• This error message is only available from software version V4.0 onwards.
3447583 Pole position identification cannot be executed because an error or trouble is active.
3447597 Identification of pole position cannot be executed because the rotor has moved too strongly.
3447601 Pole position identification cannot be executed because either the entire motor or a motor
phase is not connected.
• This error message is only available from software version V3.0 onwards.
