SmartPAC 2 with WPC 2000 Integration User Manual 1128600
Initialization Mode 4-37
ENABLING FOOT CONTROL IN A FOOT SWITCH
When “FOOT” is highlighted on the Mode Select Menu, switch 3 controls how the Foot
Switch must be activated in order to initiate and complete a stroke, as shown in Table 4-7.
Switch 3 Foot Switch settings apply only to Single-stroke operation.
When switch 3 is set to OPEN, the Foot Switch is in Foot Trip mode, which requires only that
the operator depress the Foot Switch, without holding it down, to initiate and complete a
stroke.
When switch 3 is set to CLOSED, the Foot Switch is in Foot Control mode, which requires
that the operator depress and hold down the Foot Switch through the Auto Carry-up Angle in
order to complete a stroke. If the Foot Switch is released before the Auto Carry-up Angle,
WPC 2000 issues an Emergency-stop command to the press.
Switch 4 – Enabling Auto Compensated Top Stop (ACTS)
When you have Auto Compensated Top Stop (ACTS) firmware, switch 4 controls enabling of
the ACTS feature (see Table 4-8). ACTS is a WPC 2000 option that adjusts the Top-stop
“On” Angle to an earlier point in the stroke to compensate for increases in press speed.
ACTS is designed specifically for variable-speed presses. As the speed of the press increases,
the stopping angle increases, pushing the point at which the press actually top-stops past 360°,
or TDC. ACTS senses when the press has not stopped at TDC and compensates for this
lengthening of the stopping angle by moving the Top-stop Angle back an equivalent number
of degrees. The Top-stop Angle cannot be adjusted backward beyond 211°, the factory
setting.
Adjustment of the Top-stop Angle always lags behind press speed changes because ACTS
requires several Top-stops to fine tune its settings.
When switch 4 is set to OPEN, ACTS is disabled and the press operates normally. When
switch 4 is set to CLOSED, the ACTS feature is enabled, allowing the Top-stop Angle to be
adjusted as press speed increases.
