changes the display to the screen shown in Figure 5-
22. The
MODE switch specifies if the Hold phase will
be controlled by traveling a specified Distance or for a
specified amount of Time.
With Distance MODE selected as shown in Figure 5-
22, the parameters for Hold motion are specified in the
fields on the right and are divided into two sections:
DYNAMIC and STATIC . During the Hold, the press will
first complete the DYNAMIC phase, then the STATIC
phase. In the DYNAMIC phase, the press moves
vertically at the speed specified in Speed (mm/s) to
a distance specified in Collapse (mm) . In the STATIC
phase, the press will maintain its position for the time
specified in
Dwell Time(s) . It is possible to bypass either
the DYNAMIC or STATIC phases by programming a 0
collapse distance or a 0 dwell time, respectively.
With Time MODE selected as shown in Figure 5-23,
the parameters for specifying the hold time are vertical
speed in
Speed (mm/s) , the motion duration in Move
Time (s) , and time for maintaining the final position in
Dwell Time (s) . In addition, the Constant Thrust option
is available in the Time MODE , in which the press
travels down until reaching a specified vertical thrust
(i.e. compression force). To enable this option, press
the
Constant Thrust button. The relationship between
the vertical torque and vertical speed is illustrated in
Figure 5-24. The press will adjust vertical speed as a
response to the measured vertical thrust along the lines
on the graph. The Thrust Target is the desired vertical
thrust, which is entered into the
Thrust (%) field on the
screen. The Max . Speed is the maximum allowable
vertical speed, which will occur if the measured thrust
is 0. This value is entered in the
Speed (mm/s) field in
the DYNAMIC section.
