Cause and
correction
Assumed cause
Correction
Prevention
EtherCAT process data communi-
cations are not established for the
conveyor axis.
If the
_EC_PDSlavTbl
(Process
Data Communicating Slave Table)
system-defined variable for the
EtherCAT master of the conveyor
axis is FALSE, investigate the
error in the conveyor axis and
remove the cause.
If you execute the MC_SyncLine-
arConveyor (Start Conveyor Syn-
chronization) instruction right after
you turn ON the power supply,
download data, or reset slave
communications error, make sure
that the
_EC_PDSlavTbl
(Process
Data Communicating Slave Table)
system-defined variable for the
EtherCAT master is TRUE for the
node of the conveyor axis before
you execute the instruction.
The slave of the conveyor axis
was disconnected.
See if a slave of the conveyor axis
is disconnected.
Do not disconnect a slave from the
master axis during execution of
the MC_SyncLinearConveyor
(Start Conveyor Synchronization)
instruction.
An Absolute Encoder Current
Position Calculation Failed error
(64580000 hex) was detected for
the conveyor axis.
See if an Absolute Encoder Cur-
rent Position Calculation Failed
error (64580000 hex) occurred for
the conveyor axis and make suit-
able corrections to restore opera-
tion.
Do not execute the MC_SyncLine-
arConveyor (Start Conveyor Syn-
chronization) instruction for a
conveyor axis in an Absolute
Encoder Current Position Calcula-
tion Failed error (64580000 hex).
