Position Jumps at the Display Limits of Absolute
Encoder Emulation
Using SSI emulation, it is possible to represent 4096 revolutions as an
absolute measurement. When the display limits are reached with SSI
emulation, small position fluctuations will lead to large jumps in the
emulated SSI position.
This is the case with position 0 followed by 4096 revolutions.
Fig. 8-34: SSI Display Limits
To prevent this effect, the SSI position value must be moved using
parameter
C010 Homing, Set absolute position.
It is recommended that parameter C011, Reference distance be used to
move the position to the middle of the SSI display range. Then it is
possible to travel 2048 revolutions to the left and right.
