Troubleshooting 5-19
Check the diameter of the shaft on which the magnet is mounted to make sure
there is enough dwell for the overrun limit switch to provide an adequate signal
(see Planning Your Overrun Sensor Installation, page 2-26). An ideal diameter is
4 in. to 6 in. If the shaft is larger than this, mount the magnet on a shaft with a
smaller diameter.
Check to make sure that the press is not encountering excessive shock and
vibration due to operations such as blanking. If you cannot resolve the problem,
contact Wintriss Tech. Support.
Overrun Limit Switch Test Angle Fault
Problem: The overrun limit switch was not closed during the overrun sensor closure test
window (see step 12, page 3-9) or open at 180°.
Remedy: The resolver drive may have slipped or broken. If this is the case, the resolver
needs to be repaired or replaced. If the resolver drive checks out, also check the
wiring and installation of the resolver (see Installing the Resolver, page 2-20).
Check the diameter of the shaft on which the magnet is mounted to make sure
there is enough dwell for the switch to provide an adequate signal (see Planning
Your Overrun Sensor Installation, page 2-26). An ideal diameter is 4 in. to 6 in. If
the shaft is larger than this, mount the magnet on a shaft with a smaller diameter.
Check installation of the overrun sensor and magnet and wiring of the overrun
sensor, referring to Installing the Overrun Limit Switch, page 2-25 and Mounting
the Overrun Sensor Magnet, page 3-9.
Overrun Limit Switch Setting Fault
Problem: The angle range (e.g., 271° to 300°) within which the Top-stop “On” Angle must
fall has not been set correctly on option switches 1 and 2 on S101 on the WPC
2000 Main Processor board.
Remedy: Set switches 1 and 2 on S101 for the correct Top-stop “On” Angle window,
referring to Table 3-2, page 3-8. If the error persists, contact Wintriss Tech.
