Infinite rotation absolute function
Outline
Function to set the upper limit value of absolute encoder multi-rotation data to any arbitrary
value.
Related parameters
Class No.
Title
Function

Absolute
encoder setting
Sets the method of using the absolute encoder.
0: Use under absolute system (Absolute mode).
1: Use under incremental system (Incremental mode).
2: Use under absolute system (Absolute mode) but multi-
rotation counter overflow is ignored
3: For manufacturer use (please do not set)
4: Used under absolute system (Absolute mode) but the
upper limit value of the multi-rotation counter can be
set to any value. Multi-rotation counter overflow is also
ignored. (Infinite rotation absolute mode)

Absolute multi-
rotation upper
limit value
Sets the upper limit value for absolute multi-rotation data.
When the multi-rotation data exceeds this set value, the
multi-rotation data will turn to 0.
Inversely, if it goes less than 0, it will change to the set
value.
When Pr0.15 is set to 0 or 2 (absolute mode), the upper limit
value for the absolute multi-rotation data shall be 65535,
regardless of the set value
Notes
・
This setting will become effective when PR0.15 “Absolute encoder setting” is set to 4 and
the control power supply is reclosed.
・
In case of discrepancy in the encoder multi-rotation data upper limit value and the driver
parameter multi-rotation data upper limit value when the control power supply is reclosed,
Err92.3 “Multi-rotation data upper limit value mismatch error protection” will always be
triggered, however this is not an abnormal condition.
By reclosing the driver control power supply, the phenomenon will not reappear again.

Please refer to 4-7-1-1 for Absolute system configuration.
