Cause and
correction
Assumed cause Correction Prevention
A motion instruction was executed
for an axis for which the Servo is
OFF. Correct the program so that the
instruction is executed after the
Servo is turned ON. Execute an axis motion instruction
only after the Servo is turned ON.
A zero position preset was per-
formed with the MC_Home
(Home) instruction or MC_Home-
WithParameter (Home with
Parameters) instruction for an axis
for which EtherCAT process data
communications are not estab-
lished. If the _ EC_PDSlavTbl (Process
Data Communicating Slave Table)
system-defined variable for the
EtherCAT master of the master
axis is FALSE, remove its cause
and execute the MC_Home or
MC_HomeWithParameter instruc-
tion to preset home after
_EC_PD-
SlavTbl changes to TRUE.
Write the program to make sure
that the
_EC_PDSlavTbl (Process
Data Communicating Slave Table)
system-defined variable for the
EtherCAT master is TRUE if you
execute the MC_Home or
MC_HomeWithParameter instruc-
tion to preset home immediately
after you turn ON the power supply
to the Controller, download data,
reset a slave communications
error, disconnect the slave, recon-
nect the slave, enable the slave, or
disable the slave.
