The function block MC_GearInPos synchronizes a slave axis precisely with a master axis (flying saw). The
synchronization velocity is achieved exactly at the synchronous position of the master and slave.
The master axis must already be moving, otherwise synchronization is not possible.
The slave axis can be uncoupled with the function block MC_GearOut. If the slave is decoupled while it is
moving, then it retains its velocity and can be halted using MC_Stop or MC_Halt.

Execute The command is executed with a rising edge at Execute input.
RatioNumerator Gear ratio numerator.
Alternatively, the gear ratio can be specified as a floating point
value, if the denominator is 1.
RatioDenominator Gear ratio denominator
MasterSyncPosition The master's synchronous position
SlaveSyncPosition The slave's synchronous position
SyncMode
In the data structure SyncMode [}41] boundary conditions for the
synchronization process are specified via individual flags.
MasterStartDistance Currently not implemented
Velocity Maximum slave velocity in the synchronization phase. If a velocity is
not specified, the maximum velocity of the axis from the System
Manager data is used.
The velocity given here is only checked if this checking is
activated through the SyncMode [}41] variable.
