MSpeed (Motor Speed)
The MSpeed parameter controls the time required for a motor to complete movement when
changing from one position to another from the longest (DMX value = 0) to the shortest (DMX
value = 65535). MSpeed provides a means for all motors to reach their target position at the
same time, even though each motor may have different distances to travel. MSpeed
movement is extremely smooth because the fixture controls movements independent of DMX
refresh rates. MSpeed provides a balance between quick response and smooth motion with
some lag.
MSpeed times vary from 0.15 seconds to 252.7 seconds. However, when MSpeed is applied to
a parameter, the delay value (length of time allowed for the entire scene) needs to be longer
than the MSpeed value to allow the motors to complete their movement before the end of the
cue.
An MSpeed value that is longer than the delay value can be used to smoothly change
directions or in creating circles or ballyhoos. It could also produce an undesirable result; for
example, no light output during the scene. For a listing of exact MSpeed times, see MSpeed
Conversion Table on page 37.
Note: The MSpeed option applies to Mirror Head movement speed. Mirror head
speed can also be varied using XFADE time on most DMX consoles. If a
DMX controller cannot perform a smooth 16-bit XFADE, an MSpeed
between 95-99% may greatly improve smoothness.
