Resolution of CANopen absolute encoder
[-01] =
Multi-turn resolution - number of possible encoder rotations
[-02] =
Single-turn resolution - resolution per encoder rotation
The array [01] describes the number of possible rotations depending on the
encoder resolution / multi-turn resolution. On the other hand, array [02]
describes the resolution of a singe rotation /single-turn resolution. Both
resolutions are given in bits.
NOTE:
If a single-turn encoder is used, a 0 must be parameterised in
Array [01] for the 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

The speed ratio is set for incremental and absolute encoders.
This is also effective for synchronous control (Master- Slave, P610).
