Lenze c550 User Manual

8.1.9.2 "Operaonal" EtherCAT state is not achieved
The EtherCAT bus can only reach the Operaonal state if the eldbus has already been set to
the Pre-Operaonal state.
If the master is set to the RUN mode, the EtherCAT bus will be set to the Operaonal state.
8.1.9.3 A slave does not accept a cyclic frame
In the Operaonal state, the process data is exchanged cyclically.
If a slave does not accept the cyclical frame (WKC is not increased), this error is caused.
Cause
•
The bus cable between two EtherCAT devices has been unplugged.
•
The node at posion X is deenergised.
•
A slave no longer receives cyclical frames, such that the watchdog determined by the device descripon is
triggered. This message will usually only be transmied if the connecon to the master has been re-established.
Error message
•
EtherCAT_Master: Not all slaves 'Operational' (repeated 100 times)
•
EtherCAT_Master: Not all slaves 'Operational' (repeated 10 times)
•
EtherCAT_Master: Cyclic command WKC error (repeated 10 times) [DeviceName]
(1002): Communication to device interrupted
•
EtherCAT_Master: Not all slaves 'Operational' (repeated 1 time)
•
EtherCAT_Master: Cyclic command WKC error (repeated 1 time)
•
EtherCAT_Master: Cyclic command WKC error (repeated 100 times)
Remedies
Correct bus topology and restart the EtherCAT eldbus. 4Restart network ^ 46
8.1.9.4 The sync manager conguraon is invalid
When the status changes from Pre-Operaonal to Safe-Operaonal, a slave reports Invalid
SyncManager Conguraon.
Cause
•
One of the slaves does not support an LRW command (Logical Read/Write).
•
A slave is not wrien to correctly.
Error message
[DeviceName] (1001): Invalid SyncManager Configuration
Remedies In the EtherCAT master tab, do not select the "Use LRW instead of LWR/LRD" checkbox.
8.1.9.5 The I/O conguraon is invalid
When the status changes from Pre-Operaonal to Safe-Operaonal, a slave reports Invalid
Output Conguraon.
Cause The process data conguraon of a slave is not correct.
•
In case of a modular device such as the I/O system 1000 (EPM-Sxxx), the conguraon in the project does not
comply with the real assembly.
•
More process data than permissible is mapped for the device.
Error message
•
[DeviceName] (1001): Slave signals Error. AL state: ‘PRE-OPERATIONAL' (0x12),
AL state code: 'Invalid Input Configuration' (0x1E)
•
[DeviceName] (1001): Slave signals Error. AL state: ‘PRE-OPERATIONAL' (0x12),
AL state code: 'Invalid Output Configuration' (0x1D)
Remedies
•
In case of modular devices such as the I/O system 1000 (EPM-Sxxx): Correct the control conguraon in the »PLC
Designer« (adjustment with the real structure).
•
Reducon of the process data: The maximum process data length must not be exceeded (see also the device
documentaon).
8.1.9.6 Error during process data transfer
A faulty EtherCAT I/O mapping causes errors during the process data transfer.
Cause Use of logic addresses
•
In the »PLC Designer« applicaon, access does not take place symbolically but directly via the I/O addresses (%Ixx,
%Qxx) of the EtherCAT input and output objects and the bus structure, the PDO selecon etc. have changed.
Error message -
Remedies In the »PLC Designer« applicaon, the input and output objects must be accessed via individual non-ambiguous
variables. The variable names must comply with the IEC 61131 syntax (no space characters and leading digits in the
variable names).
Cause Manual denion of the logic address in the EtherCAT I/O mapping
Error message -
Remedies It is not permissible to manually manipulate the I/O addresses for the EtherCAT bus!
