Event name
Master Axis Position Read Error
Event code

Meaning
The synchronized instruction was not executed because an error occurred in the position of the master axis of the syn-
chronized instruction.

Prevention
EtherCAT process data communica-
tions are not established for the mas-
ter axis of the synchronized
instruction.
If the
_EC_PDSlavTbl
(Process Data
Communicating Slave Table) system-
defined variable for the EtherCAT
master of the master axis is FALSE,
investigate the error in the master
axis and remove the cause.
If you execute synchronized instruc-
tions 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
master axis before you execute the
synchronized instruction.
The slave of the master axis for the
synchronized instruction was discon-
nected.
Check the slave of the master axis
and reconnect it if it was discon-
nected.
Make sure that the slave of the mas-
ter axis is not disconnected during
execution of a synchronized instruc-
tion.
An Absolute Encoder Current Position
Calculation Failed error (6458000
hex) was detected for the master axis
of a synchronized instruction.
See if an Absolute Encoder Current
Position Calculation Failed error
(64580000 hex) occurred for the mas-
ter axis and make suitable corrections
to restore operation.
Do not use an axis with an Absolute
Encoder Current Position Calculation
Failed error (64580000 hex) as the
master axis in a synchronized instruc-
tion.
