curve" on these parameters. For a given velocity, a higher accel rate will equate to a shorter accel time, and
a lower accel rate will equate to a longer accel time.
The acceleration time is the amount of time needed for the set to get to the selected velocity at the current
acceleration rate. Touching the + acceleration adjustment button will increase the acceleration time, meaning
that the set will start more gradually. Touching the - acceleration button will reduce the acceleration time,
meaning that the set will come up to speed more abruptly. Similar to the velocity, the desired acceleration
time or deceleration time can also be directly entered by touching the numeric field associated with these
values. .
The desired travel time for a move can be entered by touching the Recorded Travel Time numeric field at the
bottom of the screen. A keypad will pop up that the operator may use to key in the desired number of
seconds for a move. When this is done, the system will calculate the required maximum velocity, and will
display the acceleration time and deceleration time at the current accel and decel rates. These values will
appear in the appropriate fields in this window.
If an operator enters a value that is inappropriate (i.e. time too short for the set maximum speed) the system
will calculate the actual time required for the move. The requested velocity will be adjusted to 100% and the
acceleration and deceleration times will be displayed for the current rates. The acceleration and deceleration
rates will not change until the operator changes them, using the adjustment wheels.
Velocity values are entered after entering target values. When the operator enters a velocity number, the
system checks to make sure it is possible to attain the requested velocity in the space between the current
position and the target. If the requested speed is too fast for the distance, a box will pop up showing the
maximum speed that will be attained in the space allotted, given the current acceleration and deceleration
rates. This box will also indicate the actual acceleration time and deceleration times at the current accel and
decel rates.
Caution!
Decreasing the acceleration and deceleration times will result in more abrupt starts and
stops for the set. Extreme settings of these values can result in greatly increased shock
load on the flown equipment, particularly when using high set velocities.
Once the settings for target, velocity and accel/decel (or run-time) have been entered, the operator may run
the active preset by pushing and holding the active GO TARGET button. Alternatively, a second preset may
be set up by touching the other button icon on the lower right corner of the screen, then assigning values to
this preset. When done assigning values, the operator pushes and holds the desired GO TARGET button to
run the set to the target. If there are variable-speed motors involved in the preset, their speed may be varied
using the joystick, as described in the Shortcut section, above.
The Deadman Button (DMB) can be used to continue execution of a target move. Once the GO TARGET
button has been pressed, the operator may press and hold the DMB button to continue execution of the
move. The next cue may now be loaded onto the GO TARGET button, and the GO TARGET button pressed,
to begin the next cue. Once the next cue has begun, the control of this cue can be passed to the DMB, as
long as the DMB remains pressed.
During the move, the blue position arrow(s) on the left of the Vertical Position display will move to indicate the
set motion toward target; the blue solid figure(s) on the 3-D display will move to indicate set motion toward
target. At the bottom of the Velocity window, the travel time indicators will update to reflect the move time
remaining. All of which is very interesting, but your job as operator is…WATCH THE PIECE!
