• Upper limit of the unlimited length axis = P5AA04 − 1
• Lower limit of the unlimited length axis = 0
P5AA04: Command unit/1 machine rotation
With the unlimited length axis, even when SL021A: No. of multi-turns is not
zero, the target position and reached position will match.

−2 −1
This is a function to provide software limit value on the coordinate system to
prevent the machine from moving outside of the specified operating range.
Normally, the limit value is set before the hardware limit sensor.
• Timing to detect the limit is only during axis movement (command output).
It is not checked before operations.
• Before exceeding the limits, the following alarms will occur to stop the
axis:
• 3005h: Positive direction software limit
• 3006h: Negative direction software limit
• The software limit function is not applicable for the unlimited length axis
and the axis without an origin.
