Getting Started U511 User’s Manual
2-4 Aerotech, Inc. Version 1.1
2.5. Software Configuration Considerations
The UNIDEX 511 can be configured for a variety of motor and feedback devices.
Modification of this configuration can be accomplished from the Setup menu screen. The
configuration information is saved internally as a parameter file “*.PRM.”
If a complete system was purchased from Aerotech, including positioning stages and
cables, the UNIDEX 511 already contains a functional parameter file named
“xxxxxx.PRM”; where “xxxxxx” refers to the sales order number and serial number.
For a detailed discussion of the parameters listed in this section (and others) refer to the
individual parameter listings found in Chapter 4: Parameters.
2.6. Special Startup Considerations
It is recommended that several functions be verified prior to enabling an axis for motion.
To facilitate this verification process, a Diagnostics window is provided in the U511
software package. This Diagnostics screen displays hardware (limits, I/O, etc.) and servo-
related information (traps, machine position, etc.) dynamically (in real time). It is useful
for system setup and debug purposes. The Diagnostics window is accessed from the
DIAG key on the main screen.
The UNIDEX 511 software also contains a tracking display window that shows position
data in real time. The position is displayed in programmable units that the operator may
define (e.g., mm, in, etc.). The axis positions can be viewed from the MDI mode or the
program screens.
Make certain that all system traps and faults are enabled prior to initiating any axis
movement. For more information, refer to the faults, traps, and mask parameters in
Chapter 4: Parameters.
2.6.1. Feedback Verification
Before enabling any axis, is it important to verify the feedback from the motors. This is
done using the axis position display. The tracking display should be stable while the axis
is stationary (that is, the values in the axis position display windows should not change),
although slight movement with high resolution systems is normal.
