How to execute the pole position identification:
1. Inhibit the controller if it is enabled, e.g. via the
signal at the X5/RFR terminal.
2. Start the pole position identification with the device command
= "1: On / start".
3. Enable the controller again.
• The pole position identification starts.
• The progress of the identification run can be seen in
• The identification is completed if the "0: Off / ready" message is displayed in
4. Inhibit controller again.
After successful completion...
...the controller is inhibited automatically and the pole position determined for the activated
feedback system is set in the corresponding subcode of
• For a permanent acceptance of the identified pole position, the parameter set must be saved
(
= "1: On / start").
• The next controller inhibit and subsequent controller enable serve to cancel the controller
inhibit automatically set by the procedure (e.g. by first executing the device command
= "0: Off / ready" and then executing the device command
= "1: On /
start").
In the event of a fault
If an error occurs during the procedure or the pulse inhibit gets active (e.g. due to short-time
undervoltage), the procedure is terminated with controller inhibit without making a change in
.
If the machine was braked or blocked during the procedure, this will be recognised at the end of the
measurement and no change is made in
.
• If the pole position identification is aborted:
• the response parameterised in
(Lenze setting: "Fault") is activated.
• the error message "
Id5: Pole position identification error
" is entered into the logbook.
