The slave drive cannot autonomously reference if there is a permanent
coupling. Instead, the master drive specifies the referencing motion.
Using passive referencing, the slave drive can also be referenced.
When executing passive referencing, the slave drive is precisely re–
positioned at its own reference point.
The following commissioning help is available to determine and enter
the reference point offset for the slave drive.
This means, e.g. that it is possible, for a gantry group, to automatically
correct any possible skewing.
Passive referencing is possible for axes with absolute or incremental
encoder. However, the drive with the absolute value encoder must first
be adjusted using absolute value setting (Fault 176).
