Configuring the Adapter
For example, if Parameter 76 - [DLs Fr Peer Cfg] is set to receive five
Datalinks (Datalinks 12 through 16) and the first of those five Datalinks
(Datalink 12) contains the Logic Command, set Parameter 78 - [Logic
Src Cfg]
to a value of ‘1’. Otherwise, set Parameter 78 to a value of ‘0’. For
Logic Command bit definitions, see
or the drive
documentation.
8.
If a Reference is being sent, use Parameter 79 - [Ref Src Cfg] to set the
number of the Datalink that contains the Reference within the range
defined by Parameter 76 - [DLs Fr Peer Cfg].
For example, if Parameter 76 - [DLs Fr Peer Cfg] is set to receive five
Datalinks (Datalinks 12 through 16) and the second of those five
Datalinks (Datalink 13) contains the Reference, set Parameter 79 - [Ref
Src Cfg]
to a value of ‘2’. Otherwise, set Parameter 79 to a value of ‘0’.
9.
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.
10.
Reset the adapter by power cycling the drive or by using the HIM’s Reset
Device function located in the drive’s DIAGNOSTIC folder so that
changes to Parameter 76 - [DLs Fr Peer Cfg] take effect.
11.
Set Parameter 85 - [Fr Peer Enable] to a value of ‘2’ (Custom).
Setting a Fault Action
By default, when communication is disrupted (for example, the network cable is
disconnected), the controller is idle (in program mode or faulted), and/or peer
I/O or explicit messaging for drive control is disrupted, the drive responds by
faulting if it is using I/O from the network. You can configure a different
response to these faults:
•
Disrupted I/O communication by using Parameter 54 - [Comm Flt Action].
•
An idle controller by using Parameter 55 - [Idle Flt Action].
•
Disrupted peer I/O by using Parameter 56 - [Peer Flt Action].
•
Disrupted explicit messaging for drive control via PCCC, the CIP
Register Object or the CIP Assembly Object by using Parameter 57 -
[Msg Flt Action]
.
