SinCos multi-turn with programmable transmission factor
When using a SinCos multi-turn, you can use the S2 option to adapt the range of
the absolute position S12 to your application via a transmission factor. S12 then
always contains the position value referenced to the reset path P96.
Positioning is still implemented with reference to the actual value in Status S1.
SinCos multi-turn records an absolute position of 4096 rotations.
In applications such as controlling a round table via a transmission, the position of
the table cannot be determined very accurately because 4096 rotations usually
signifies several rotations of the table.
By specifying the transmission factor P96 (ratio of motor : table), the absolute
position S12 is reset to 0 after a table rotation. After "Power on" and after an error
has occurred, S12 is transferred as the actual value (S1=S12).
The function is switched on via P206="1".

Please note
♦ Set P1=0. Using P212=10 (see Page 80) you can still select the machine zero
point as required.
This function does not affect the actual positioning process.
Example:P96=10 (sensor revolutions); P83=40 000
µ m (40mm)
After POSA 450 and then POSA 0, the drive reverses by 450 mm (and
not just 50 mm).
To execute a positioning process within the reset path after traveling in
one direction for a long time, evaluate S12.
E.g.: required position within the reset path = 10 mm
