8506 Sercos Master comm. not possible
Refer to Diagnostic class (standard): 3
Sercos communication interrupted because no link is detected on either port.
|
Cause |
Solution |
|---|---|
|
Wiring error (cable separated) |
Verify and correct if necessary the wiring. |
|
Non-operating Sercos slave after the controller. |
Verify the state of the device and reset or replace if necessary. |
Sercos communication interrupted because more than the allowed numbers of sequentially DTs are not operating.
|
Cause |
Solution |
|---|---|
|
Wiring error (cable separated) |
Verify and correct if necessary the wiring. |
|
Non-operating Sercos slave. |
Verify the state and condition of the device and reset or replace if necessary. |
In two consecutive cycles, an error is detected on the Sercos bus while receiving data. The Sercos bus is shut down.
NOTE: Loss of position of the axes and physical encoders (SinCos, incremental encoder) is possible as a consequence of error acknowledgment of diagnostic message 8506 Sercos Master communication not possible without restarting the controller.
|
|
|
POSITION LOSS DUE TO SERCOS BUS ERROR |
|
Acknowledge the diagnostic message only after reinitialization or homing of the system has been ensured by the program. |
|
Failure to follow these instructions can result in injury or equipment damage. |
The capability to acknowledge the diagnostic message can be switched off with the function FC_DiagNoQuitSet(). If necessary, use the function FC_SysReset() or FC_PrgResetAndStart().
NOTE: The diagnostic message 8112 Sercos telegram invalid is not triggered for telegram breakdowns within the system since the Sercos slave can no longer report the diagnostic code to the controller via the Sercos bus. In this case, diagnostic code 8506 Sercos Master communication not possible is reported.
|
|
|
IMPOSSIBLE TO EVALUATE THE DIAGNOSTIC MESSAGE DUE TO INTERRUPTED CONNECTION |
|
Evaluate the diagnostic message 8506 Sercos Master communication not possible when evaluating the diagnostic message 8112 Sercos telegram invalid in order to help ensure specific reaction also during telegram breakdowns. |
|
Failure to follow these instructions can result in injury or equipment damage. |
