Resolver faults

Problem: In either of these cases, there is a problem with the resolver assembly.
Remedy: You will need to check the resolver and wiring. Specifically check that
the terminals are tightened on bare wire and not on insulation. See
Chapter 2 - "Mounting the resolver." If necessary, contact Wintriss Tech
Support for assistance or replacement.
Problem: The press is going faster than WPC's rated speed, or the resolver has
failed. Or it may just be that wiring in the resolver circuit to WPC is loose
or bad.
Remedy: If WPC's rated press speed is exceeded, reduce the speed. If not, check the
resolver wiring and connections for shorts, breaks, or loose connections.
See Chapter 2 "Mounting the resolver" for complete information about
resolver wiring. If the wiring is not the problem, the resolver is probably
bad and will have to be replaced. If necessary, contact Wintriss Tech
Support for assistance or replacement.
Problem: "The resolver position is different from when the unit was turned off."
This message will only appear if SmartPAC detects a different resolver
angle position from the time that the press was turned off to when it was
turned on again. This can happen when you move the press or upgraded
SmartPAC firmware.
Remedy: Press RESET to clear. If the message reappears, contact Wintriss Tech
Support.
Problem: This error occurs during the resolver zeroing process. It means that the
resolver had been set outside the range of 330° to 30°.
Remedy: The resolver needs to be re-zeroed properly at top dead center (TDC).
