4-32 Initialization Mode
page 7-20) and prevents the press from starting. The Start-time Limit setting enables WPC
2000 to monitor operation of the resolver and detect resolver drive failure.
The Start-time Limit default is 1998 mS, which is set when WPC 2000 is initialized (see
Initializing WPC 2000 Parameters
, page 4-34). The setting is automatically changed to twice
the starting time measured by WPC 2000 on the first stroke after initialization.
Wintriss recommends that you use this automatic setting as your Start-time Limit. If you
decide to change the setting, you should enter a value at least 40% greater than the measured
start time of your press. You can view the most recent starting time on the Stop Time Status
screen in Run mode (see page 6-21).
Example
Your measured start time is 250 mS. Take 40% of 250 (i.e., 0.40 x 250 = 100) and add the result
to 250 (i.e., 100 + 250 = 350). Your calculated Start-time Limit is 350 mS.
Setting the Shutdown Time (Optional)
The Shutdown Time setting is the length of time WPC 2000 waits after the DSV de-energizes
before shutting off the press motor. When the DSV is de-energized, the motor may still be on
even though the press is not actually running. WPC 2000 uses the Shutdown Time value to
turn off the press motor if the DSV is not re-energized after the specified length of time. An
F10 fault code (see page 7-7) is displayed on the SmartPAC 2 LCD when the press has been
stopped. You can set the Shutdown Time to any value between 0 and 100 minutes.
Setting Flywheel Timer (Optional Hardware Required)
The Flywheel Timer setting allows WPC 2000 to prevent the press motor from being reversed
or Bar mode from being activated whenever the flywheel is turning at a speed greater than the
specified number of seconds per revolution.
A flywheel speed sensor must be installed in order for WPC 2000 to implement the Flywheel
Timer setting. The flywheel sensor monitors the length of time it takes the flywheel to turn
one revolution. As the flywheel slows down, the time for one revolution increases. The
Auto-compensated Top Stop (ACTS) firmware is required in order for WPC 2000 to implement the
Shutdown Time setting.
Since WPC 2000 uses the lockout relay to shut off the press motor when the Shutdown Time has
expired, the lockout relay must be wired to the motor starter in order for the Shutdown Time setting
to function (see page 2-34).
A flywheel speed sensor must be installed in order for the Flywheel Timer to function. See
page 2-43.
