If you are making your own feedback cables, see the Kinetix 5100 Feedback
Battery Box Installation Instruction, publication
, for information to
install or replace a battery box, install a battery, and prepare a feedback cable for a
battery box installation.
For additional information on making your own feedback cables, see
Kinetix 5100 Feedback Connector Kit Installation Instruction, publication
, for information on motor feedback cables that provide wire
terminations for encoder signals to the motor feedback (MFB) connector on
Kinetix 5100 drives.

System Initialization
When you initialize the absolute system for the first time, a fault (A 060 Absolute
Position Lost) occurs because the coordinate system has not been created. Clear
the fault by configuring the coordinate system. Insufficient battery power or the
failure of the main power supply also causes loss of the coordinate system and the
reoccurrence of A 060. In the absolute system, when the PUU position value goes
outside the range -2147483648 … 2147483647, A 289 (Feedback position
[PUU] counter overflow) occurs.
Except for the faults mentioned above, you can use Bit 2, Overflow warning
setting of ID243 (P2.070) DataReadUnitSelection to set up the absolute servo
system. You can choose not to show A 289 if the absolute coordinate system
overflows when the PUU exceeds the range -2147483648 … 2147483647. For
example, you might do this on a system that uses incremental commands to
operate in one direction.
ID243 (P2.070) setting:
1.
Initialize the absolute coordinates.
NOTE:
The system that is shown is an example.
Your system can be different.
