To change PDO mapping first disable the mapping by writing 0 to 0x1A0x-0. Write the desired mapping entry and enable
the mapping again by writing the number of PDO contents to 0x1A0x-0.
6.4.2
Default mapping of absolute encoder redundant with cable-pull
The mappings for both PDOs are the same. The position will be transmitted in byte 0..3.
