Chapter 2 Configure Integrated Motion Using a PowerFlex 755 Drive
Create a Motion Group
All axes must be added to the Motion Group in your project. If you don’t group
the axes, they remain ungrouped and unavailable for use.
1. Click New Group.
2. Typ e a name.
You must create a Motion Group for an axis to be configured properly.
You can have eight Position Loop axes per 1756-EN2T module. Each drive
requires one TCP and one CIP connection. If you have other devices that
consume TCP connections on the module, it reduces the number of drives you
can support. Only the drives/axes configured for Position Loop are limited.
Frequency Control, Velocity Loop, and Torque Loop configured drives/axes are
not limited.

Controller Communication Modules Supported Axes
(1)
(1) Multiple controllers can control drives on a common 1756-ENxTx module, so based on the TCP connection limit, up to 128 can be supported.
Position Loop Other Loop Types CIP_Drives

(2) If more than the maximum I/O modules are configured in the I/O tree under Embedded Ethernet, then you will get a Project Verify Error:
Error: Maximum number of nodes on the local Ethernet port has been exceeded.
