0: Fix (S9-19 [Wire Length])
Uses the setting value of S9-19 [Wire Length]. The wire length can also be changed in steps
using S9-28 to S9-30 [Correction value1 to 3 of Wire Length].
1: External (Analog Input)
Uses the input value of an analog input terminal. The set wire length can be changed
according to the analog input value. 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 analog output 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].
