12.5.7 Shafts make clicking noises

If the shafts make clicking noises, this is often caused by faulty synchronisation or a shift of data in

the process image.

Cause The task and DC cycle times set in the logic/motion system differ.

Error message -

Remedies Adjust the task cycle time and DC cycle time.

Adjusting the task cycle time and DC cycle time

( 88)

Cause Wiring error: The EtherCAT terminals (IN/OUT) of the slave were inverted.

A fieldbus scan does not indicate this error!

Error message EtherCAT_Master: Set master 'Operational' failed. DCM not in-sync

Remedies Correct wiring.

Afterwards, reload the »PLC Designer« application into the automation system.

Cause Clicking noise of the shafts after "out-of-sync"

If due to a fault, the preset DC deviation limit is exceeded, a re-synchronisation of the DC

slaves is carried out until the slaves are synchronised again ("In-Sync") and the DC deviation

is under the preset limit value again.

Currently, the Lenze Controller is not re-synchronised to the distributed clocks so that the

sync pulses of the master and the ones of the slaves are different.

Error message EtherCAT_Master: DC slaves 'out-of-sync'. Deviation xxxxxxxx ns

Remedies Restarting the EtherCAT fieldbus

( 159) so that the DC slaves and the DC master

synchronise again.

Cause Wrong selection of the device sync source (9400 HighLine CiA402, C01120)

After the sync source has been changed by C01120, the subsequent download and the

setting of the slave to the "Operational" state may fail

Error message -

Remedies • Manual setting of code C01120 to MXI1 or MXI2

• Repeated download with PLC start

• Restarting the EtherCAT fieldbus

( 159) with reset of the SoftMotion drive
