Integrated Motion on EtherNet/IP
Special considerations when using PowerFlex 755 drives in Integrated Motion on
EtherNet/IP mode:
•
A PowerFlex 755 drive does not have the performance of a Kinetix servo
and is not intended to be a replacement.
•
When a PowerFlex 755 is used in Integrated Motion on EtherNet/IP
mode, the Logix controller and RSLogix 5000 are the exclusive owners of
the drive (same as Kinetix). A HIM or other drive software tools, such as
DriveExplorer and DriveTools SP, cannot be used to control the drive or
change configuration settings. These tools can only be used for
monitoring.
•
The following peripherals can be installed, see
for valid ports and supported combinations:
–
HIM (20-HIM-A6 / -C6S) - monitor only
–
Universal Feedback Encoder Option (20-750-UFB-1)
–
Incremental Encoder Option (20-750-ENC-1)
–
Dual Incremental Encoder Option (20-750-DENC-1)
–
Safe Torque Off Module (20-750-S)
–
Safe Speed Monitor Module (20-750-S1)
–
24v Aux Control Power Supply (20-750-APS)
Other peripherals, such as 20-750 I/O modules, are not allowed.
•
Not all drive functions are available when used in an Integrated Motion on
EtherNet/IP application. See the
Parameter / Instance Attribute Mapping
tables in this appendix to view which drive parameters correlate to motion
attributes. If a parameter is not listed, it is not accessible and its function is
not be available. Examples of functions that are not available include:
–
DeviceLogix
–
Pump Jack and Pump Off
–
Torque Prove
–
P Jump and Traverse
PowerFlex 755 Update

Course Update Period (network)
3 ms min. (6 ms min. when used with a permanent
magnet motor without feedback)
Torque loop

Velocity loop

Position loop
1024 us
ATTENTION: A Kinetix drive automatically reads a permanent magnet motor /
encoder’s configuration data, whereas the user must manually enter / tune it
with the PowerFlex 755. If incorrect data is entered, unintended motion could
occur when a Motion Servo On (MSO) instruction is executed.
