Uses the input value from MEMOBUS communications. The set wire length can be changed
according to the input value from MEMOBUS communications. When this parameter is used in
combination with Wire Length Detection of the lifting and lowering shaft drive, U9-06 [Wire
Length] will change according to the detected value of Wire Length Detection.
If the center of
gravity position of the wire tip changes due to the condition of the suspended cargo, correct
for this using S9-28 to S9-30 [Correction value1 to 3 of Wire Length].
(a) When There is Little Change in the Center of Gravity Position of the Wire Tip from the
Center of the Lifting and Lowering Shaft Drum (A ≒ B)
(b) When There is a Large Change in the Center of Gravity Position of the Wire Tip from the
Center of the Lifting and Lowering Shaft Drum (C
≠ D)
