onous I/O Refre
shing
With synchronous I/O refreshing, you can match the timing for the processing that is performed by the
Controller and the Unit’s pulse output.
You can use synchronous I/O refreshing with more than one Unit to operate more than one stepper
motor or Servomotor at the same time.
*1. For an NX-series CPU Unit, the task period of the primary periodic task or priority-5 periodic task is applica-
ble. For an NJ-series CPU Unit, only the task period of the primary periodic task is applicable.
Operation of Synchronous I/O Refreshing
on page 5-7 for details.
Precautions for Correct Use
If you use synchronous I/O refreshing, set the task period to a value within the specified refresh
cycle range of the Position Interface Unit.
Use the following procedure to select
Enabled (DC for synchronization)
from the
Enable Distributed
Clock
setting for the EtherCAT Coupler Unit and use synchronous I/O refreshing for Pulse Output Input
Units that are connected to an EtherCAT Coupler Unit.
