Prevention
The power supply for the host
controller was shut off during PDO
communications.
Execute an error reset on the host
controller. This is only a
notification of an error that was
detected when the power supply
for the host controller was shut off,
not the error that has occurred.
When you shut off the power
supply for the host controller, also
shut off the power supply for the
Servo Drive.
An EtherCAT communications
cable is disconnected, broken, or
incorrectly connected.
Connect the EtherCAT
communications cable securely. If
the cable is broken, replace it.
Connect the EtherCAT
communications cable securely.
Noise
Take noise countermeasures if
excessive noise is affecting the
EtherCAT communications cable.
