Checking the direction of rotation
| Please note that for proper operation the count direction of the feedback system must match the sequence of the motor phases. Turn the motor shaft clockwise, viewed from the A-side. The parameter “Position feedback 1 value” (see lower image) should be positive. If this is not the case, the sine and cosine signals at the motor should be swapped. |
| If the motor has a holding brake, it can be released in the TCDriveManager under “Service functions/ Manual operation” (see lower image).
Now use the command P-0-0166 to check the counting direction of the feedback system and whether it matches the connection of the motor phases.

Motor movement! When you check the counting direction of the motor with the command P-0-0166, the motor will move. Therefore, please keep a safe distance from the motor with all body parts before you start the command P-0-0166! |
| The AX5000 must be set inactive without error (diag code = 0x0000D012). After selecting the command P-0-0166 press “Start”. Confirm the selection (Do you really want to continue?) with “Yes”.
The command P-0-0166 was successfully completed when the message “Succeeded to start the command” appears in the context menu. The verification result can now be read in parameter P-0-0167. If the “Equal Directions” selection area shows 0: No, change the order of the motor phases (The direction of rotation of the feedback system was already checked and possibly corrected in the previous step). |
 | Please do not use a TwinCAT setting to change the motor phases at the motor connection. Swap motor phases U and V, for example, at the motor connector plug (X13/X23). |
If the “Equal Directions” selection area now shows 1:Yes, the commutation offset can be determined based on one of the following methods.
