The Number of Samplings Set-
ting was set to other than 1 and
the Enable Distributed Clock set-
ting for the EtherCAT Coupler
Unit was set to Disabled.
Set the Enable Distributed Clock
setting for the EtherCAT Coupler
Unit to Enabled (DC for synchro-
nization) or Enabled (DC with pri-
ority in cycle time) and then
download the Slave Terminal pa-
rameter settings again.
For the High-speed Analog Input
Units, synchronous I/O refresh-
ing is always used. Therefore,
set the Enable Distributed Clock
setting for the EtherCAT Coupler
Unit to Enabled (DC for synchro-
nization) or Enabled (DC with pri-
ority in cycle time).
