Integrated Motion on EtherNet/IP Appendix E
If there are two ways to wire a particular encoder to a particular feedback module,
then selecting “Channel A” for a feedback module from the “Associated Axes”
page selects one set of terminals, and selecting “Channel B” selects another set of
terminals.
Table 5 shows the legal Integrated Motion on EtherNet/IP Feedback types and
the correct encoder connection terminals when the feedback module is a 20-750-
ENC-1.
Table 5 - Single Incremental Encoder Feedback Type and Connections
Table 6 shows the legal Integrated Motion on EtherNet/IP Feedback types and
the correct encoder connection terminals when the feedback module is a 20-750-
DENC-1.
Table 6 - Dual Incremental Encoder Feedback Type and Connections
The following table shows the legal Integrated Motion on EtherNet/IP Feedback
types and the correct encoder connection terminals when the feedback module is
a 20-750-UFB-1. It also shows how the two “Device Select” parameters on the
20-750-UFB-1 are configured in each case.
When a 20-750-UFB-1 is used in an Integrated Motion on EtherNet/IP system,
the “FB0” parameters are always used for configuration and status of Channel A
and the “FB1” parameters are always used for configuration and status of
Channel B.
Table 7 shows that, for some Integrated Motion on EtherNet/IP Feedback Types,
there are two possible connection schemes. If the RSLogix 5000 user selects
Channel A, one scheme is used. If the RSLogix 5000 user selects Channel B, the
other scheme is used. Conversely, for the other Integrated Motion on EtherNet/
IP Feedback Types, there is only one possible connection scheme.
The “Digital AqB” Feedback Type is a special case. If only one of the channels on
a particular 20-750-UFB-1 is configured to “Digital AqB”, then the A, B, and Z
terminals are used, regardless of whether this type is assigned to Channel A or
Channel B. If both channels are configured to “Digital AqB”, then Channel A
uses the A, B, Z terminals, and Channel B uses the terminals that are labeled
“Sine” and “Cosine”. In this case they are expected to carry normal AqB encoder
signals. These two cases are included in the table.
