Correction
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.
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.
Take noise countermeasures if
excessive noise affects the Ether-
CAT communications cable.
If this event occurs again after you
performed all corrections shown
above, replace the Servo Drive.
