The unidirectional SL mini speed and length gauge interprets motion in either direction as a positive
speed and an increase in length, thus correct length accumulation requires that the object must only
move in one direction (reverse motion will incorrectly cause the length to increment, not decrement).
Length measurements during line stoppage may exhibit a positive error due to microscopic vibration
of the object; hence it is recommended that the “
Length
hold” function on the SL mini logic input is
activated by the line controller when the line is stationary to temporarily suspend speed measurement
and length accumulation.
For production lines that require correct length accumulation during direction reversals or line
stoppage (without using the “
Length
hold”
function), it is recommended that the SLR mini is used.
