“Angle Resolver Failure”
Explanation: The wiring in the resolver circuit to SmartPAC 2 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 2).
Remedy: Check the resolver wiring and connections for shorts, breaks, or loose
connections (see Wiring the Resolver, page 2-12). If SmartPAC 2’s rated
press speed has been exceeded, reduce the speed. If the speed hasn’t been
exceeded, make sure that the speed has been set correctly (see Setting Up
High Speed Version of SmartPAC 2 (Optional), page 2-41). If these
remedies do not correct the problem, the resolver may need to be replaced.
Contact the factory for assistance.
“Input check circuit failure”
Explanation: The resolver turned five times, indicating that the press was running, but
SmartPAC 2 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 2-15. 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 2-25, page 2-38). Also, a
position sensor may be enabled in Initialization without a position sensor
being installed.
To clear this fault, you must cycle power to SmartPAC 2. Pressing RESET does not work.
