Configuring the Option Module
1.
Set
Device Parameters 41 - [To Peer Period] and 42 - [To Peer Skip] as
desired for your application.
Parameter 41 controls how frequently the option module will transmit
data when it is changing. Parameter 42 controls how frequently the option
module will transmit data when it is not changing.
2.
Set
Host Parameter 31 - [DL To Net 15] to point to the drive parameter
[Drive Logic Rslt], which is parameter 879 for PowerFlex 753 drives and
PowerFlex 755 drives.
3.
Set
Host Parameter 32 - [DL To Net 16] to point to the drive parameter
[Drive Ref Rslt], which is parameter 883 for PowerFlex 753 drives and
PowerFlex 755 drives.
4.
Set
Device Parameter 39 - [DLs To Peer Cfg] to value of “2.”
5.
Set
Device Parameter 43 - [To Peer Enable] to a value of “2” (Custom).
Follow these steps to set up the slave (receiver) side of simple peer I/O.
1.
Set
Device Parameter 32 - [Fr Peer Timeout] to a suitable timeout value
for your application.
This value should be greater than the product of
Device Parameter 41 -
[To Peer Period]
and
Device Parameter 42 - [To Peer Skip] in the
transmitting drive.
2.
Set
Device Parameters 33 - [Fr Peer Addr 1] through 36 - [Fr Peer Addr
4]
to the IP address of the drive transmitting peer I/O.
3.
In each PowerFlex 750-Series slave drive, set drive parameter 308 -
[Direction Mode] to “0” (Unipolar) to be sure that it properly follows the
master drive’s speed reference and commanded direction.
4.
Set
Device Parameter 37 - [Fr Peer Enable] to a value of “1” (Cmd/Ref ).
Custom Peer I/O Configuration
Peer I/O also allows more flexibility in sending custom data over the network,
but requires more configuration.
Follow these steps to set up the master (broadcast) side of custom peer I/O.
IMPORTANT
Because of the 32-bit REAL (floating point) Reference, the following method
works only if the drives transmitting and receiving are PowerFlex 750-Series
drives.
