The M/S Synchronization Offset can be used in the electronic gear functionality to
align the Slave drive to the absolute position of the master drive.
Comply with chapter 14.4.10.1 “Master/Slave Position Correction”.
NOTE
When using this functionality master drive and slave drive have to use the same
mechanical characteristics (i.e. gear transmission ratios) and use the same reference
system.
The values of Object 0x5F18/0 are limited as follows:
