3 Error Descriptions and Corrections
Input Process Data Invalid Error
Event name
Because the EtherCAT master could not perform process data communications normally when it was in
the Operational state, the Input Data Invalid state continued for the following period.
Meaning
When the task period is 10 ms or shorter: 100 ms
When the task period is longer than 10 ms: 10 periods of the task

Correction
While disconnecting the slaves
from the network one by one, cor-
rect the error until the _EC_In-
DataInvalid (Input Data Invalid),
_EC_InData1Invalid (Input Data1
Invalid), and _EC_InData2Invalid
(Input Data2 Invalid) system-
defined variables change to
FALSE. When any of these vari-
ables changes from TRUE to
FALSE, the slave disconnected at
that time is considered as failed.
Replace the slave.
In addition, program the _EC_In-
DataInvalid (Input Data Invalid),
_EC_InData1Invalid (Input Data1
Invalid), and _EC_InData2Invalid
(Input Data2 Invalid) system-
defined variables as an interlock
condition in the user program to
ensure that invalid input data
does not cause unexpected oper-
ation.
Check the number of error frames
in the slave diagnostic and statis-
tical information. It is considered
that the slave was affected by
noise in each location where an
error frame was counted. Imple-
ment appropriate noise counter-
measures for all locations
considered to be affected by
noise. Then, make sure that error
frames are no longer counted in
the slave diagnostic and statisti-
cal information.

If error frames are still counted in
the master diagnostic and statisti-
cal information, before you start
operation, remove the noise
source or implement noise
countermeasures while checking
the slave diagnostic and statisti-
cal information.
