Refer to Diagnostic class (standard): 3
Further bus communication is not possible due to a detected bus error.
NOTE: No data exchange with bus terminal BT-4 ENC1. Position loss of the master encoder connected to bus terminal BT-4/ENC1. Acknowledge the diagnostic message only after reinitialization or homing of the system has been acknowledged by the program. If necessary, use the function FC_SysReset() or FC_PrgResetAndStart().
|
Cause |
Solution |
|---|---|
|
Detected wiring error: Incorrect bus topology. |
Verify and correct or replace if necessary the terminals, transmission lines, and so on. |
|
EMC errors found. |
Verify and correct or replace if necessary the wiring and EMC protection. |
|
Ext. diagnosis |
Meaning |
|---|---|
|
asynchronous |
A synchronization error is detected. The touchprobes on the BT-4/DIO1 are not working. Verify the jumper cable that connects the controller to the optional module PN-4 (in the controller). |
|
clock miss |
A communication error is detected in PacNet. This may be due to various causes: oPacNet loop not closed oPacNet terminating plug is missing oA module connected to PacNet is inoperable (for example, no power) Verify the PacNet loop and the modules in the loop. |
|
Cause |
Solution |
|---|---|
|
Sercos cycle time 4 ms and PacDrive LMC-FPGA version < V0x02 (x = Hardware-ID, for example Id=2 -> FPGA version = V0202) |
Update PacDrive LMC-FPGA version to at least version V0x02 |
