56 Chapter 8 – SmartPAC PRO Fault Messages
“Angle resolver failure”
Explanation: The wiring input check circuit failure in the resolver circuit to SmartPAC PRO
may be loose or bad, or the resolver may have failed. Another possible cause is
that the press may be going faster than 800 SPM (or 1600 SPM, depending on
the speed setting in SmartPAC PRO).
Remedy: Check the resolver wiring and connections for shorts, breaks, or loose
connections; see
Wiring the Resolver , page 24.
•
If SmartPAC PRO’s rated press speed has been exceeded, reduce the speed.
•
If the speed has not been exceeded, make sure that the speed has been set
correctly.
•
If you purchased the high-speed option (up to 1600 SPM), make sure it is
enabled on the Options Manager screen,
OPTIONS MANAGER in Chapter 3 ,
SmartPAC PRO Initialization Mode , in your user manual.
•
If these remedies do not correct the problem, the resolver may need to be
replaced. Contact the Wintriss Tech. Support for assistance.
NOTICE
To clear this fault, you must cycle power to SmartPAC PRO.
“Input check circuit failure”
Explanation: The resolver turned five times, indicating that the press was running, but
SmartPAC PRO received no signal from the input check circuit. The input
check circuit may not have been connected or wired properly. If this message
occurs when the press stops, the brake may be worn.
Remedy: Check the wiring of the input check circuit and rewire, if necessary,
following the instructions in
Connecting Stop Circuits and Input Check
Circuit
, page 27. If the input check circuit is not the problem, check
your brake for wear.
“Position sensor incorrect”
Explanation:
The position sensor was not closed at 0

or was not open at 180

.
The position sensor, which cross-checks the position of the resolver to ensure
that it is working correctly, should be installed so that it closes at zero resolver
degrees. If it does not close at 0

or is not open by 180

, the press stops and you
see this message.
The resolver drive may have slipped or be broken, or the resolver or position
sensor may be defective or not installed properly. Another possibility is that the
position sensor may not have enough dwell to close at high speeds. The larger
the diameter of the object on which the magnet is mounted, the shorter the dwell
(see Figure 2-20, page 48). Also, a position sensor may be enabled in
