2.6 Motors
Three crystal controlled tri-phase motors are in use: one for the claw mecha-
nism, one for the magazine drive, one for the shutter. Penelope is capable of
speeds between 3 and 40fps with a standard Li-Ion 14.8V battery.
Film frame-rate
Penelope provides preset crystal speeds (SYNC) and Operator tuned crystal
speeds (VAR) in .001 increments, all accessible from the LCD control panel.
NOTE: once the frame-rate is set, the thousandths are not displayed.
Available preset speeds are : 6, 12, 18, 20, 23.98, 24, 25, 29.97, 30, 33.33,
36 and 40fps. The «sync» key allows for quick access to these frequently
used speeds.
If any other speed is desired, or if the camera speed must match the fre-
quency of a monitor to eliminate a rolling bar, the «var» key should be
employed. The speed selector gives access to any speed between 3 and
40fps in .001 frame steps. A phase adjustment of the variable speed is avail-
able while pressing the «left» and «right» keys.
The camera speed can also be adjusted while the camera is running in either
sync or variable mode. For more information on these speed functions, refer
to the «LCD control panel and jog wheel» section of this chapter.
