SmartPAC 2 with WPC 2000 Integration User Manual 1128600
Installation 2-79
The press cannot be run in Continuous or Single-stroke unless the overrun sensor and magnet
are installed and working correctly. Without the overrun limit switch, you can only operate
the press in Inch.
The angle at which you mount the magnet depends on the Top-stop “On” Angle, the angle at
which the Top-stop cam turns on, initiating a Top-stop. You must first determine and set the
Top-stop “On” Angle before installing the magnet.
Setting the Top-stop “On” Angle
In the following procedure, you
•
Set the Top-stop “On” Angle to 270°
•
Top-stop the press three times to determine an average angle at which the press stops
•
Use the average angle value to calculate the actual Top-stop “On” angle
•
Set the calculated Top-stop “On” Angle
To calculate and set the Top-stop “On” Angle, perform the following steps:
1.
Make sure the following WPC 2000 features are set correctly:
•
Option switches 1, 2, and 4 on switch block S101 on the WPC 2000 Main Processor
board should be set to OPEN (see page 4-35 for instructions).
When switches 1 and 2 are “open,” you can set any Top-stop Angle between 211° and
355°.
When switch 4 is “open,” the Auto Compensated Top Stop (ACTS) feature is disabled.
ACTS compensates for increases in press speed by adjusting the Top-stop Angle
backward (i.e., decreasing the angle).
•
Pin #13 on the WPC 2000 Main Processor board should not be connected. When pin
#13 is unwired, Top-stop in Inch is enabled (see page 6-42).
•
Micro-inch should be disabled (see page 4-29 for instructions).
2.
Power down, then power up the SmartPAC 2 to enable the new settings.
For a variable-speed press, you need to determine the latest Top-stop “On” Angle, which is the
angle at which the press top-stops at its slowest speed and with the shortest stopping angle/time.
BEFORE YOU SET THE TOP-STOP ANGLE, MAKE SURE THAT
• The press ram has been mechanically set to top dead center (TDC) (see NOTICE on page 2-3)
• The resolver has been aligned as close as possible to TDC (i.e., 0° ±2°) (see
Mounting the
Resolver
, page 2-25)
• The resolver has been zeroed (see page 2-78)
