Cause The EtherCAT bus could not be set to the "Operational" state
 The EtherCAT bus does not assume the "Operational" state ( 176)
Error message -
Remedies  The EtherCAT bus does not assume the "Operational" state ( 176)
Cause Clicking noise of the shafts after "out-of-sync"
 Error during process data transfer ( 178)

Cause Faulty SoftMotion scaling/mapping
With SoftMotion scaling/mapping, the increments per revolution are not set.
Error message -
Remedies Check the following settings and correct them if required:
• Gearbox ratio in the »PLC Designer« application
• Mapping settings in the master configuration
When the Lenze Controller is started, the complete configuration/PDO mapping is written
into the EtherCAT slaves. When this is done, mapping entries, e.g. from the »Engineer« are
overwritten.
Tip: In the case of the Servo Drive 9400 HighLine Cia402, 65536 increments per revolution
are correct.
