Event name Master Axis Position Read Error
The synchronized control instruction was not executed because an error occurred in the position of the
Meaning
master axis of the synchronized control instruction.

Assumed cause
EtherCAT process data commu-

the master axis of the synchro-
nized control instruction or the I/O
data of the NX Unit cannot be
used for control.
Cause and
correction
The slave of the master axis for
the synchronized control instruc-
tion was disconnected or dis-
abled.
An Absolute Encoder Current
Position Calculation Failed error
(64580000 hex) was detected for
the master axis of the synchro-
nized control instruction.
The master axis for the synchro-
nized control instruction is an
unused axis.

Data type
BOOL
Correction
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 the master
axis is assigned to an NX Unit,
perform the same correction for
the process data communicating
status of the NX Unit.
Check the slave of the master
axis and reconnect if it was dis-
connected or enable it if it was
disabled.
See if an Absolute Encoder Cur-
rent Position Calculation Failed
error (64580000 hex) occurred
for the master axis and make
suitable corrections to restore
operation.
Set the master axis to a Used
Axis.

Prevention
If you execute synchronized con-
trol instructions 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) sys-
tem-defined variable for the Eth-
erCAT master is TRUE for the
node of the master axis before
you execute the synchronized
control instruction. If the master
axis is assigned to an NX Unit,
perform the same correction for
the process data communicating
status of the NX Unit.
Make sure that the slave of the
master axis is not disconnected
or disabled during execution of
the synchronized control instruc-
tion.
Do not use an axis with an Abso-
lute Encoder Current Position
Calculation Failed error
(64580000 hex) as the master
axis in the synchronized control
instruction.
Do not change the master axis to
an unused axis when executing
synchronized control instructions.
