(2) Rotation direction setting
Set how the current position would increase/decrease in each rotation direction of the motor. Check the settings
by JOG operation. ( Page 104, Section 7.9)
1.
Set "Current Value Increment with Forward Run Pulse Output" for the rotation direction setting
and perform forward JOG operation.
2.
If the workpiece moves in the address decreasing direction defined by the system, set "Current
Value Increment with Reverse Run Pulse Output" for the rotation direction setting to change the
rotation direction. (If the workpiece moves in the address increasing direction defined by the
system, the current setting need not be changed.)
3.
Perform forward JOG operation again and if the workpiece (W) moves in the address increasing
direction, the setting is complete.

Forward run pulse
If Rotation Direction Setting was changed from "Current Value Increment with Forward Run Pulse Output" to "Current Value
Increment with Reverse Run Pulse Output," perform JOG operation to check if the upper limit switch and lower limit switch
operate correctly. If any operation problem was found, review the wirings.
(3) S/W stroke upper limit, S/W stroke lower limit
Set the upper/lower limits of the moving range of the workpiece.
• Set the software stroke limits according to the condition specified below:
Software stroke lower limit < Software stroke upper limit
• To disable the software stroke limits, set the same value for both the upper limit and lower limit. (Desired
values can be set as long as they are within the setting range.)
