4-10 Operation
Micro-inch
Micro-inch allows finer adjustments than are possible in Top-stop in Inch or Top-stop Bypass
and is designed to facilitate setup on high-speed or short-stroke presses. In Micro-inch, the
distance the ram moves is controlled by a time setting you make on the WPC 2000 display
(see Setting Micro-Inch, page 3-25). When that time has elapsed, the ram comes to a stop
even though the Run/Inch palm buttons are still depressed.
The ram can be stopped before the end of the Micro-inch time by releasing one or both Run/
Inch buttons. To move the ram through a complete stroke in Micro-inch, you must “inch” the
press. Micro-inch has no Top-stop feature.
Wiring instructions are provided in Wiring Micro-inch, page 2-33.
Dead Motor Inch
Dead Motor Inch is a feature that allows you to operate the press in Inch mode for a short time
after the main motor is turned off, using the energy stored in the flywheel. Dead Motor Inch
allows the press to be inched in smaller increments than is possible when the press is running,
and is useful during setup. To activate Dead Motor Inch, do the following:
1.
Turn off the press motor.
2.
Turn the Stroke Select switch to “INCH.”
3.
Press both Run/Inch buttons to initiate a stroke, releasing them when the ram has moved
the desired distance. Repeat this process until the flywheel has stopped turning.
INTERRUPTED STROKE
When Micro-inch is enabled, WPC 2000 automatically switches to Two-hand Maintained
Single-stroke during an Interrupted Stroke even though the press is in Inch. Normally, WPC 2000
remains in Inch during an Interrupted Stroke. See Responding to an Interrupted Stroke, page 4-3.
