Ring counter setting (Ver.1.10 or later)

This function causes the current address to perform the ring operation within the range from 0 to the preset
ring counter upper limit value.
The current address (user) performs the ring operation within the range from 0 to the preset ring value. The
current address (pulse) performs the ring operation within the range from 0 to the preset ring value converted
into pulses.
The 20SSC-H Ver. 1.30 or later supports unlimited length feed in ring operation when the absolute position
detection system is used.
No setting is necessary for unlimited length feed.
However, the reciprocal movement instruction does not support unlimited length feed in ring operation when
the absolute position detection system is used.
Caution
When the absolute current position from the zero-point exceeds the range of 32 bit data (-2,147,483,648 to
2,147,483,647), the current value overflow flag in the status information is ON.
Since 20SSC-H units earlier than Ver.1.30 do not support unlimited length feed in "ring operation" when the
absolute position detection system is used, an error (error code: 3004) occurs at the next power startup in this
case.
