Anti-reverse mode
P1320[0] - MPRO_ECAM_CamMaster_RevLockMode is used to define the reverse
lock mode, which can be used either with or without path compensation. The dashed
lines in the following diagrams indicate what the engagement distance is:
 INACTIVE (0) = Reverse lock disabled
Theslavewillfollowthemasterdirectlyineverydirection.
 ACTIVE WAY COMP (1) = Reverse lock enabled - with path optimization
Whiletheslaveisacceleratingtothemaster’sspeedduringengagement,the
masterandtheslavewillnotmovesynchronously.Thisfunctionneedstobe
selectedinordertoquicklycatchuptothemasterthatisrunningahead.
 Master(blackline)rotatesintheblockeddirection
 Theslave(blueline)willremainstopped
 Masterrotatesintheunblockeddirection
