Map the inputs and outputs of the instance of the
PSM_REF
,
DAM_REF
, and
ACM_REF
function blocks and the physical data
points of the PSM 510/DAM 510/ACM 510 accordingly.
6.5.12 Setting the PLC Cycle Time
The minimum cycle time is 400 µs. The servo system devices can run Ethernet POWERLINK
®
cycle times in multiples of 400 µs and
multiples of 500 µs. The devices are automatically parameterized by the PLC on start-up, depending on the Ethernet POWERLINK
®
configuration of the physical interface.
The Ethernet POWERLINK
®
configuration can be accessed by right-clicking [PLK
→
Configuration] in the
Physical View
.
N O T I C E
Ensure that the task cycle times of the PLC program and Ethernet POWERLINK
®
are the same. Otherwise, data could be lost
and performance reduced.
