Commission the iTRAK 5730
System
The iTRAK 5730 system must be commissioned properly to provide accurate
mover position feedback on the
on how to establish smooth mover transitions between motor module sections.
Motor Module Section Gap Position Compensation
To control mover positions accurately on the track system, the motor modules
monitor feedback from the mover position magnets. Motor module sections
can report different absolute positions at the gap where modules adjoin. To
reconcile the difference in the reported absolute positions, the motor module
sections calculate a position compensation. The position compensation is
applied to the boundaries between sections to produce smooth mover section-
to-section transitions.
To calculate the position compensation, the motor module sections must
identify the absolute position differences at all transitions as movers traverse
the track. The calculated values for the position compensation are measured
for each mover and stored in nonvolatile memory. After subsequent power
cycles, each motor section reads nonvolatile memory and immediately applies
the appropriate position compensation. Take the following into consideration
when deciding whether or not you will assign a reference mover:
•
When you configure a reference mover, the correct sequence number
and position compensation are applied automatically to each mover in
the system after a power cycle.
•
When you do not configure a reference mover, position accuracy across
motor module gaps can be degraded after a power cycle.
ATTENTION: A pinch point hazard exists. A mover can have sudden and fast motion
due to magnetic attraction. To avoid personal injury, do not put your fingers
between the mover and motor module.
You can assign a 'reference' mover and mover sequence numbers in the Mover Axis
Assignment Sequence' field in the Module Properties - Track Configuration dialog box.
You must complete the Calculate and Store Position Gap Compensation Values
procedure in these cases:
•
After initial iTRAK 5730 system installation is complete, and before it is
put into service
•
After a motor module has been replaced
•
After a mover has been replaced, or removed from or added to the track
system
•
After the 'Mover Axis Assignment Sequence' field selection has been
changed
This procedure assumes that you have configured your iTRAK 5730 system,
your Logix 5000 controller, and applied power to the system.
Before you commission the iTRAK 5730, verify that the MOD and NET status
