6.14Overflowinmulti-turnrange
With this function the multi-turn range can be shifted in order to avoid a possible
overflow. The function is available for encoder channels 1 and 3.
Example
If a portion of the travel distance is to the left of the threshold (MT Base), it is
appended to the end of the travel range (to the right of the 2048) via parameter
P547[0] - ENC_CH1_MTBase for encoder channel 1 and P584[0] - ENC_CH3_ for
encoder channel 3 (unit: increments).
For more information see Section "Main parameters for encoder channel Ch1" on
page 60 andSection "SinCos incremental encoders with absolute value interface" on
page 66.
