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.
