Identify pole position (360°)
If no absolute value encoder is connected, or a synchronous motor of a third-party manufacturer is
driven by the controller, the
= "51: Identify pole position (360°)" device command is used to
determine the pole position with regard to the motor encoder currently activated in
.
• 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 motor carries out one electrical revolution. This
leads to a mechanical rotation of the motor shaft.
• The determined pole position is indicated under code
Tip!
Detailed information on the pole position identification can be found in the chapter "Motor
interface", subchapter "

the response parameterised in
(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.
