Checking the Resolver’s Direction of Rotation
To determine whether you have wired the resolver so that it rotates in the correct direction, do
the following:
1.
Run the press in Inch mode, and observe whether the crankshaft angle shown in the digital
LED display increases or decreases.
•
If the angle increases (i.e., moves from 0° to 1°, 2°, 3°, etc.), the resolver wiring is
correct. Go to the next section.
•
If the angle decreases (moves from 0° to 359°, 358°, 357° etc.), the yellow and black
resolver wires are reversed. Go to step 2.
2.
Rewire the yellow and black resolver wires correctly, referring to Table 2-21, page 2-63
and Figure 2 at the end of the manual.
3.
Inch the press again, and observe the movement of the crankshaft angle in the LED
display. The angle should now increase.
4.
If the direction of rotation is still incorrect, contact Wintriss Tech Support.
Replacing the Resolver
If you need to replace your resolver, do the following:
1.
Perform the Mounting the Resolver and Wiring the Resolver procedures, above.
2.
Rezero the resolver, following the instructions in Re-zeroing the Resolver, page 3-4.
Installing the Overrun Limit Switch
The overrun limit sensor, also called the “overrun sensor,” enables WPC 2000 to monitor
operation of the resolver and to stop the press whenever the resolver fails to work properly, as
can happen when the resolver drive chain breaks or slips or when the resolver is broken. The
overrun sensor provides a signal to WPC 2000 at the same resolver angle on every stroke.
Whenever this angle changes, WPC 2000 detects that the resolver is no longer rotating at a 1:1
ratio with the crankshaft and sends an Emergency-stop command to the press, simultaneously
displaying an error code.
MOUNT OVERRUN LIMIT SWITCH SO IT PROVIDES CORRECT TIMING
• Install the overrun limit sensor magnet on a component, such as the crankshaft, that moves
independent of the resolver and whose motion is not affected by the condition of the resolver or
the resolver’s drive mechanism. Safe operation of the press depends on the overrun limit
sensor working correctly when the resolver or its drive mechanism fails.
• Install the overrun limit sensor magnet in the correct angular location according to the
instructions starting on page 3-6.
Failure to comply with these instructions will result in death or serious injury.
