Combination With Other Devices; Precautions - Mitsubishi Electric MELSEC iQ-R Series User Manual

Control details
AxisName.Md.SetPosition to be the ring address is calculated based on AxisName.Md.CumulativePosition. The cumulative
current position will be the ring address of "-10000000000.0  cumulative current position < 10000000000.0" regardless of the
setting of the ring counter upper/lower value.
Ex.
When the ring counter lower limit value is -500000000.0 and the ring counter upper limit value is 500000000.0, the set
position is the ring address of "-500000000.0  set position < 500000000.0".

The ring counter upper/lower limit value is fetched to the parameter at the timing when the axis is enabled.

Combination with other devices

The available range of positioning differs depending on the type of the positioning instruction.
• Absolute position specification: Within the range of the ring counter
• Relative position specification: Maximum movement amount | 10000000000.0 |

Precautions

When AxisName.PrConst.RingCount_Enable is "1: Enabled", error is checked.
If the ring counter upper/lower limit value is set as follows, an error will occur.
• The ring counter upper/lower limit value is set outside the positioning range.
• The ring counter lower limit value > The ring counter upper limit value
• | The ring counter upper limit value - The ring counter lower limit value | < 2.0
