◆ Descriptions of Parameters
Figure 3.2 Wire Length Detection

S9-01 Wire Length Detection Selection
Enables and disables Wire Length Detection.
No. Name Setting Range Default Setting
S9-01 Wire Length Detection Selection 0, 1 0
0: Disabled
1: Enabled
Perform the following procedure for the default settings.
• Hoist the hook to the hoisting limit position, and then input Forward Travel Limit or set S9-
03 to 1 [Hook Position Information Reset] to reset U9-01 [Hook Position (NumR)] to zero.
• Lower the hook to the lowering limit position, and set S9-04 [Hook RangeLim Number of
Rotation] to the value indicated by U9-01 at this time.
 S9-02 Hook Position Inform @Power down
Selects whether to hold or reset the hook position information when the power supply is turned
OFF.
No. Name Setting Range Default Setting
S9-02 Hook Position Inform @Power down 0, 1 0
0: Hook Position Reset @Power down
Resets the position information each time the power supply is turned ON. Detect the origin
position with one of the following options.
• Hoist the hook to the hoisting limit position, and then input Forward Travel Limit or set S9-
03 to 1.
• Lower the hook to the lowering limit position, and then input Reverse Travel Limit.
• When using S9-07 [Home Position Number of Rotation], move the hook to the home
position, and then input Home Position Set.
oPL [Origin Position Loss Detected] will be output until the origin position is detected.
1: Hook Position Hold @Power down
The origin position does not need to be detected each time the power supply is turned ON.
However, detect the origin position when the wire length changes while the power supply is
turned OFF, such as when maintenance is performed, and when an error occurs in Wire Length
Detection.
