Cause and
correction
Assumed cause Correction Prevention
The power supply to the host
controller was interrupted during
PDO communications
Reset the error in the host control-
ler. This event reports an error that
was detected when the power sup-
ply to the host controller was inter-
rupted. It does not indicate that an
error currently exists.
If you turn OFF the power supply
to the host controller, also turn
OFF the power supply to the Servo
Drive.
An EtherCAT communications
cable is disconnected, broken,
short-circuited, or has a contact
failure in a daisy chain configura-
tion.
Connect the EtherCAT communi-
cations cable securely. If the cable
is broken, replace it.

•Set Communications Error
Setting (2200 hex) to 2 or more.
• Connect the EtherCAT commu-
nications cable securely. If the
cable is broken, replace it.
