SET INITIALIZATION PARAMETERS BEFORE PROGRAMMING UPPER/LOWER LIMITS
Before you create settings for upper and lower limits in Program mode, be sure to set the Upper
Limit and Offset Value on the Linear Sensor Setup screen in Initialization mode (see page 84).
This item on the Tool Program Menu enables you to set upper and lower limits for your
magnetostrictive linear transducer. These settings are made on the Ram Position screen, which is
shown in Figure 5-58.
Figure 5-58. Ram Position Screen
SmartPAC PRO Servo sets the Upper Limit you specify on this screen equal to 0° and the Lower
Limit to 180°. The vertical distance between Upper and Lower limits is divided into 180 equal parts
to represent the angle range of downstroke (0° to 180°) and upstroke (180° to 360°/0°). If the ram
passes the Lower Limit on the downstroke, SmartPAC PRO Servo holds the angle at 180°. On the
upstroke, the angle begins to increase only when the ram passes the Lower Limit. Similarly, if the
ram passes the Upper Limit on the upstroke, SmartPAC PRO Servo holds the angle at 0° until the ram
moves past the Upper Limit on its downstroke.
It is extremely important to set limits for each tool precisely. If the ram returns to the Upper Limit
without reaching the Lower Limit or returns to its Lower Limit without reaching its Upper Limit,
SmartPAC PRO Servo generates a fault (see page 191), prohibiting the press from further stroking
until RESET is pressed. Although this message may display for other reasons (e.g., a light curtain
obstruction), it commonly occurs when the Lower Limit is set too low or the Upper Limit too high.
