1126800 SmartPAC 2 with WPC Integration
Page 244 Chapter 4 SmartPAC 2 Initialization Mode
Switch 4 – Auto Compensated Top Stop (“ACTS”) Enabled (Optional)
NOTICE
After you change switch settings, power down the SmartPAC 2/WPC. Power it up again to
enable the new settings. If you do not this, the previous switch settings will remain in effect.
Set this switch to CLOSED to activate the “Auto Compensated Top Stop” feature. Set to
“OPEN” to run the press in normal mode. You must have the correct optional firmware to
use ACTS.
This feature is specifically designed for variable speed presses. WPC assumes that the Top
Stop Angle (programmed previously) is set at the slowest speed (refer to “Set Top Stop
Angle and Install Overrun Magnet,” page 107), resulting in the shortest stopping angle. As
the press runs faster, the stopping angle increases. Auto Compensated Top Stop (ACTS)
notices when the press has not stopped exactly on top, and compensates the Top Stop Angle
by advancing its position. ACTS cannot advance beyond 211 degrees (the same limit as with
the manual Top Stop Angle setting). ACTS will require a few top stops so that the press
stops as close to 0° as possible. ACTS will also compensate against a longer stopping angle
due to brake wear. It is, therefore, critical to set your brake monitor correctly so that the
Brake Warning feature gives you advance notice for proper brake maintenance.
Set Switch 4 in the Press Control Option Switches screen, Figure 4 - 33, page 241.
