4.3 Absolute encoder (SSI), multiturn
General
The parameter assignment of a multiturn absolute encoder (SSI) illustrated in the following
example is performed using the "External encoder" technology object.
If the encoder belongs permanently to an axis, the "Axis" technology object is used to assign
parameters.
Note
In conjunction with ADI4, SIMOTION only supports encoders with 13-bit and 25-bit message
frames.
