4.7 Setting the Reference Adjustment
A reference adjustment is a percent scaling factor for the reference
from the network and can be set from 0 to 200%. This allows the
drive’s reference to either match the network reference (=100%),
scale below the network reference (<100%), or scale above the
network reference (>100%).
If the module is receiving a reference, adjust the scale in module
parameter 37 (Ref Adjust). It can be scaled between 0.00 and
200.00%. Refer to figure 4.12.
The adjustment takes effect as soon as it is entered.
4.8 Selecting a Master-Slave or Peer-to-
Peer Hierarchy
A hierarchy determines the type of device with which the module
exchanges data. In a Master-Slave hierarchy, a module exchanges
data with a master, such as a scanner or bridge. In a Peer-to-Peer
hierarchy, a module exchanges data with one or more EtherNet/IP
modules connected to devices that have compatible logic
command/status words.
For both master-slave and peer-to-peer hierarchies, the devices
exchanging data must be on the same IP subnet. See “IP
Addresses” in the Glossary for more information about IP subnets.
!
ATTENTION: Changes to module parameter 37 (Ref
Adjust) take effect immediately. A drive receiving its
Reference from the module will receive the newly
scaled Reference, resulting in a change of speed.
Failure to observe this precaution could result in
bodily injury or damage to equipment.
