Checking the motor phases and the encoder counting direction
If the absolute and incremental positions of the linear encoder have the same counting direction (or if there is only an incremental position), the phase sequence of the motor can be compared with the encoder counting direction. This can be checked using the command P-0-0166 "Motor and feedback connection check" (picture below).
If the command P-0-0166 has been selected for checking the motor and feedback connection (picture above), the input mask of parameter P-0-0167 appears. The parameters in the upper area should not initially be changed.
The main voltage (e.g. 400 V) must be switched on in order to execute the command. The AX5000 must be ready but not enabled. The "Diag Code" is 0x0000D012.
Notice | |
The execution of this command causes a movement of the motor! Before confirming the following message with "Yes", make sure that the motor can move freely and cannot cause any damage. |
The following message appears during the first execution:
The linear motor first jerks and then makes a further movement a few seconds later.
If the command was executed successfully, the message "Succeeded to start the command" appears. Values are hereby entered in parameter P-0-0167 "Results" (picture below).
It is important that the result "1:Yes" appears in the setting "Equal Directions" (picture above → red circle). If "0:No" should appear there, two phases of the motor connection (AX5000 X13/X23) need to be swapped, e.g. U and V.
The command can also be executed repeatedly.
