Resolution setting of the absolute encoder.
[-01] = Multi-turn resolution
number of possible encoder rotations
[-02] = Single-turn resolution,
resolution per encoder rotation
[-03] = Sin/Cos periods
Sin/Cos periods per encoder rotation (Hiperface
encoders) (SK 540E and above)
The array [-01] describes the number of possible rotations (specific to the encoder, the so-called
multi-turn resolution. Array [02] describes the resolution of a singe rotation, the so-called single-
turn resolution. Both resolutions are stated in bits.
NOTE:
If a single-turn encoder is used, a 0 must be parameterised in Array [-01] for multi-
turn resolution.

Example: Resolution = 2^12[Bit] = 4096
For a single-turn encoder with 12 bit resolution the following parameterisation must be
carried out:
Array [-01] = 0
Array [-02] = 12
