SmartPAC 2 with WPC 2000 Integration User Manual 1128600
Initialization Mode 4-29
The Auto Carry-up Angle is factory-set to 149° if your WPC 2000 has light curtain firmware
and to 170° if you have non-light curtain firmware. If you change the auto carry-up default
setting, you must use an angle value that is at or past the crankshaft angle at which the pinch
point openings on the press have closed to less than 1/4 in. (6 mm). Pinch points that are less
than 1/4 in. (6 mm) are considered non-hazardous to the operator.
With large presses where the stroke is long and press speed is slow, you must ensure that the
operator cannot release the buttons and reach the pinch point before it closes. This applies
only when Two-hand Control is used to safeguard the point of operation (without light
curtain) and only if any opening allowing access to the pinch point is 1/4 in. (6 mm) or larger.
Set the Auto Carry-up Angle at the correct value to protect the operator.
Setting Micro-inch Time and Angle
Micro-inch Time is the length of time in milliseconds that the Dual Safety Valve is open when
the operator presses the Run/Inch buttons on the Operator Station while the press is in Inch
mode.
Normally, when the press is running in Inch (see
Top-stop in Inch
, page 6-42), the DSV is
open and the clutch engaged as long as the Run/Inch palm buttons are depressed. When
Micro-inch is enabled, the clutch remains engaged only for the length of time specified in the
MICRO TIME setting on the Press Control Parameter Menu unless the operator releases the
Run/Inch palm buttons before the period has expired.
You enable Micro-inch via the MICRO ANGLE setting on the Press Parameter Control
Menu. The Micro Angle default setting is 185
°
, which disables Micro-inch. To enable this
feature, change the Micro Angle to another setting between 186
°
and 184
°
. The angle you
specify enables Micro-inch for the range of angles between that value and 185
°
.
EXAMPLE
If you set the Micro-inch Angle to 186°, the press will automatically Micro-inch throughout the
stroke from 186° to 185°.
If you set the Micro-inch Angle to 300°, the press will Micro-inch from 300° to 185°. Normal
inching resumes from 185° to 300°.
You can enter Micro-inch values from 6 to 600 milliseconds. The default value, set at the
factory, is 100 mS.
Setting Clutch and Counterbalance Air Pressure Limits
The MAIN AIR LIMIT and C/- items allow you to establish a low setpoint for
Clutch Air Pressure and a setpoint range for Counterbalance Air Pressure. Instructions for
installing sensors or switches to monitor Clutch and Counterbalance Air pressures are
provided starting on page 2-13.
The value you enter in the MAIN AIR LIMIT field sets the low limit for Clutch Air Pressure.
If clutch pressure drops below the limit, an F45 fault displays on the SmartPAC 2 LCD (see
page 7-14).
