PARA. 26: Software limit (lower)
When the present value becomes equal to or less than the set value, a limit error occurs.
• When the software limit is reached, the machine is immediately stopped in the same way as
a stop caused by the limit switches (limit error).
• The software limit becomes valid after a zero return operation or an absolute position detec-
tion is performed. After either operation is performed, the present value establish flags
M9144 (for the X axis) and M9145 (for the Y axis) are turned ON (The M9144 only is turned
ON in the FX
2N
-10GM.).
• When the value set to PARA. 25 is equal to or less than the value set to PARA. 26, the soft-
ware limit function is invalid.
• When a limit error occurs, the error code 4004 is actuated. Jog operation in the opposing
direction is possible even in the error status. When the machine is returned from an area
beyond the limit position, the error is reset.
